Uses a two-phase runtime model: setup runs before the agent phase and can access the network to install specified dependencies, then the agent phase runs offline by default unless you enable internet access for that environment. Secrets configured for cloud environments are available only during setup and are removed before the agent phase starts.24- **Codex cloud**: Runs in isolated OpenAI-managed containers, preventing access to your host system or unrelated data.

44### Network isolation

46Network access is controlled through destination rules that apply to scripts,

47programs, and subprocesses spawned by commands. When command network access is

48already enabled, turn on the `network_proxy` feature to constrain that traffic

49to the network policy you configure.

51```toml

52[features.network_proxy]

53enabled = true

54domains = { "api.openai.com" = "allow", "example.com" = "deny" }

55```

57For a one-off CLI session, use the boolean shorthand when you only need the

58toggle, and the table form when you also set policy options:

60```bash

61codex \

62 -c 'features.network_proxy=true' \

63 -c 'sandbox_workspace_write.network_access=true'

65codex \

66 -c 'features.network_proxy.enabled=true' \

67 -c 'features.network_proxy.domains={ "api.openai.com" = "allow", "example.com" = "deny" }' \

68 -c 'sandbox_workspace_write.network_access=true'

69```

71The feature changes how enabled network access is enforced; it does not grant

72network access by itself. Use `sandbox_workspace_write.network_access` with

73`workspace-write` config to decide whether commands have network access at all:

75- Network off + `network_proxy` on: network stays off, and the feature does nothing.

76- Network on + `network_proxy` off: network stays on with unrestricted direct

77 outbound access.

78- Network on + `network_proxy` on: network stays on, and outbound traffic is

79 constrained by the configured network policy.

81Admin-managed `experimental_network` requirements are separate from the user

82feature toggle. They can configure and start sandboxed networking without

83`features.network_proxy`, but they do not turn on network access when the active

84sandbox keeps it off. See [Managed configuration](https://developers.openai.com/codex/enterprise/managed-configuration#configure-network-access-requirements)

85for the administrator-side `requirements.toml` shape.

87#### Network policy

89Domain rules are allowlist-first:

91- Exact hosts match only themselves.

92- `*.example.com` matches subdomains such as `api.example.com`, but not

93 `example.com`.

94- `**.example.com` matches both the apex and subdomains.

95- A global `*` allow rule matches any public host that is not denied. Treat `*`

96 as broad network access and prefer scoped rules when you can.

97- `deny` always wins over `allow`, and global `*` is only valid for allow rules.

99#### Local and private destinations

100

101By default, `allow_local_binding = false` blocks loopback, link-local, and

102private destinations:

103

104- Specific exceptions: add an exact local IP literal or `localhost` allow rule

105 when a command needs one local target.

106- Broader access: set `allow_local_binding = true` only when you intentionally

107 want wider local/private reach.

108- Wildcards: wildcard rules do not count as explicit local exceptions.

109- Resolved addresses: hostnames that resolve to local/private IPs stay blocked

110 even if they match the allowlist.

111

112#### DNS rebinding protections

113

114Before allowing a hostname, Codex performs a best-effort DNS and IP

115classification check:

116

117- Lookups that fail or time out are blocked.

118- Hostnames that resolve to non-public addresses are blocked.

119- The check reduces DNS rebinding risk, but it does not eliminate it. Preventing

120 rebinding completely would require pinning resolved IPs through the transport

121 layer.

122

123If hostile DNS is in scope, enforce egress controls at a lower layer too.

124

125#### Dangerous settings

126

127Two settings deliberately widen the trust boundary:

128

129- `dangerously_allow_non_loopback_proxy = true` can expose proxy listeners beyond

130 loopback.

131- `dangerously_allow_all_unix_sockets = true` bypasses the Unix socket allowlist.

132

133Use them only in tightly controlled environments. When Unix socket proxying is

134enabled, listeners stay loopback-only even if non-loopback binding was requested,

135so sandboxed networking does not become a remote bridge into local daemons.

136

137`network_proxy` is off by default. When you enable it:

138

139| Setting | Default | Behavior |

140| -------------------------------------- | ------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |

141| `enabled` | `false` | Starts sandboxed networking only when command network access is already on. |

142| `domains` | unset | Uses allowlist behavior, so no external destinations are allowed until you add `allow` rules. Supports exact hosts, scoped wildcards, and global `*` allow rules; `deny` always wins. |

143| `unix_sockets` | unset | No Unix socket destinations are allowed until you add explicit `allow` rules. |

144| `allow_local_binding` | `false` | Blocks local and private-network destinations unless you add an exact local IP literal or `localhost` allow rule, or explicitly opt into broader local/private access. |

145| `enable_socks5` | `true` | Exposes SOCKS5 support when policy allows it. |

146| `enable_socks5_udp` | `true` | Allows UDP over SOCKS5 when SOCKS5 is available. |

147| `allow_upstream_proxy` | `true` | Lets sandboxed networking honor an upstream proxy from the environment. |

148| `dangerously_allow_non_loopback_proxy` | `false` | Keeps listener endpoints on loopback unless you deliberately expose them beyond localhost. |

149| `dangerously_allow_all_unix_sockets` | `false` | Keeps Unix socket access allowlist-based unless you deliberately bypass that protection. |

150

44You can also control the [web search tool](https://platform.openai.com/docs/guides/tools-web-search) without granting full network access to spawned commands. Codex defaults to using a web search cache to access results. The cache is an OpenAI-maintained index of web results, so cached mode returns pre-indexed results instead of fetching live pages. This reduces exposure to prompt injection from arbitrary live content, but you should still treat web results as untrusted. If you are using `--yolo` or another [full access sandbox setting](#common-sandbox-and-approval-combinations), web search defaults to live results. Use `--search` or set `web_search = "live"` to allow live browsing, or set it to `"disabled"` to turn the tool off:151You can also control the [web search tool](https://platform.openai.com/docs/guides/tools-web-search) without granting full network access to spawned commands.

75 182

183### Deny reads with filesystem profiles

184

185Named permission profiles can also deny reads for exact paths or glob patterns.

186This is useful when a workspace should stay writable but specific sensitive

187files, such as local environment files, must stay unreadable:

188

189```toml

190default_permissions = "workspace"

191

192[permissions.workspace.filesystem]

193":project_roots" = { "." = "write", "**/*.env" = "none" }

194glob_scan_max_depth = 3

195```

196

197Use `"none"` for paths or globs that Codex shouldn't read. The sandbox policy

198evaluates globs for local macOS and Linux command execution. On platforms that

199pre-expand glob matches before the sandbox starts, set `glob_scan_max_depth` for

200unbounded `**` patterns, or list explicit depths such as `*.env`, `*/*.env`, and

201`*/*/*.env`.

202

76### Run without approval prompts203### Run without approval prompts

83 210

84For a middle ground, `approval_policy = { granular = { ... } }` lets you keep specific approval prompt categories interactive while automatically rejecting others. The granular policy covers sandbox approvals, execpolicy-rule prompts, MCP prompts, `request_permissions` prompts, and skill-script approvals.211For a middle ground, `approval_policy = { granular = { ... } }` lets you keep specific approval prompt categories interactive while automatically rejecting others. The granular policy covers sandbox approvals, execpolicy-rule prompts, MCP prompts, `request_permissions` prompts, and skill-script approvals.

85 212

86Set `approvals_reviewer = "guardian_subagent"` to route eligible approval reviews through the Guardian reviewer subagent instead of prompting the user directly. Admin requirements can constrain this with `allowed_approvals_reviewers`.213### Automatic approval reviews

214

215By default, approval requests route to you:

216

217```toml

218approvals_reviewer = "user"

219```

220

221Automatic approval reviews apply when approvals are interactive, such as

222`approval_policy = "on-request"` or a granular approval policy. Set

223`approvals_reviewer = "auto_review"` to route eligible approval requests

224through a reviewer agent before Codex runs the request:

225

226```toml

227approval_policy = "on-request"

228approvals_reviewer = "auto_review"

229```

230

231For the full reviewer lifecycle, trigger conditions, configuration precedence,

232and failure behavior, see

233[Auto-review](https://developers.openai.com/codex/concepts/sandboxing/auto-review).

234

235The reviewer evaluates only actions that already need approval, such as sandbox

236escalations, blocked network requests, `request_permissions` prompts, or

237side-effecting app and MCP tool calls. Actions that stay inside the sandbox

238continue without an extra review step.

239

240The reviewer policy checks for data exfiltration, credential probing, persistent

241security weakening, and destructive actions. Low-risk and medium-risk actions

242can proceed when policy allows them. The policy denies critical-risk actions.

243High-risk actions require enough user authorization and no matching deny rule.

244Prompt-build, review-session, and parse failures fail closed. Timeouts are

245surfaced separately, but the action still does not run.

246

247The [default reviewer policy](https://github.com/openai/codex/blob/main/codex-rs/core/src/guardian/policy.md)

248is in the open-source Codex repository. Enterprises can replace its

249tenant-specific section with `guardian_policy_config` in managed requirements.

250Local `[auto_review].policy` text is also supported, but managed requirements

251take precedence. For setup details, see

252[Managed configuration](https://developers.openai.com/codex/enterprise/managed-configuration#configure-automatic-review-policy).

253

254In the Codex app, these reviews appear as automatic review items with a status

255such as Reviewing, Approved, Denied, Aborted, or Timed out. They can also

256include a risk level and user-authorization assessment for the reviewed

257request.

258

259Automatic review uses extra model calls, so it can add to Codex usage. Admins

260can constrain it with `allowed_approvals_reviewers`.

155- **macOS** uses Seatbelt policies and runs commands using `sandbox-exec` with a profile (`-p`) that corresponds to the `--sandbox` mode you selected. When restricted read access enables platform defaults, Codex appends a curated macOS platform policy (instead of broadly allowing `/System`) to preserve common tool compatibility.332- **macOS** uses Seatbelt policies and runs commands using `sandbox-exec` with a profile (`-p`) that corresponds to the `--sandbox` mode you selected. When restricted read access enables platform defaults, Codex appends a curated macOS platform policy (instead of broadly allowing `/System`) to preserve common tool compatibility.

156- **Linux** uses the `bwrap` pipeline plus `seccomp` by default. `use_legacy_landlock` is available when you need the older path. In managed proxy mode, the default `bwrap` pipeline routes egress through a proxy-only bridge and fails closed if it can’t build valid local proxy routes.333- **Linux** uses `bwrap` plus `seccomp` by default.

182 359

360### Run Codex in Dev Containers

361

362If your host cannot run the Linux sandbox directly, or if your organization already standardizes on containerized development, run Codex with Dev Containers and let Docker provide the outer isolation boundary. This works with Visual Studio Code Dev Containers and compatible tools.

363

364Use the [Codex secure devcontainer example](https://github.com/openai/codex/tree/main/.devcontainer) as a reference implementation. The example installs Codex, common development tools, `bubblewrap`, and firewall-based outbound controls.

365

366Devcontainers provide substantial protection, but they do not prevent every

367 attack. If you run Codex with `--sandbox danger-full-access` or

368 `--dangerously-bypass-approvals-and-sandbox` inside the container, a malicious

369 project can exfiltrate anything available inside the devcontainer, including

370 Codex credentials. Use this pattern only with trusted repositories, and

371 monitor Codex activity as you would in any other elevated environment.

372

373The reference implementation includes:

374

375- an Ubuntu 24.04 base image with Codex and common development tools installed;

376- an allowlist-driven firewall profile for outbound access;

377- VS Code settings and extension recommendations for reopening the workspace in a container;

378- persistent mounts for command history and Codex configuration;

379- `bubblewrap`, so Codex can still use its Linux sandbox when the container grants the needed capabilities.

380

381To try it:

382

3831. Install Visual Studio Code and the [Dev Containers extension](https://marketplace.visualstudio.com/items?itemName=ms-vscode-remote.remote-containers).

3842. Copy the Codex example `.devcontainer` setup into your repository, or start from the Codex repository directly.

3853. In VS Code, run **Dev Containers: Open Folder in Container...** and select `.devcontainer/devcontainer.secure.json`.

3864. After the container starts, open a terminal and run `codex`.

387

388You can also start the container from the CLI:

389

390```bash

391devcontainer up --workspace-folder . --config .devcontainer/devcontainer.secure.json

392```

393

394The example has three main pieces:

395

396- `.devcontainer/devcontainer.secure.json` controls container settings, capabilities, mounts, environment variables, and VS Code extensions.

397- `.devcontainer/Dockerfile.secure` defines the Ubuntu-based image and installed tools.

398- `.devcontainer/init-firewall.sh` applies the outbound network policy.

399

400The reference firewall is intentionally a starting point. If you depend on domain allowlisting for isolation, implement DNS rebinding and DNS refresh protections that fit your environment, such as TTL-aware refreshes or a DNS-aware firewall.

401

402Inside the container, choose one of these modes:

403

404- Keep Codex's Linux sandbox enabled if the Dev Container profile grants the capabilities needed for `bwrap` to create the inner sandbox.

405- If the container is your intended security boundary, run Codex with `--sandbox danger-full-access` inside the container so Codex does not try to create a second sandbox layer.

Details

3Codex app-server is the interface Codex uses to power rich clients (for example, the Codex VS Code extension). Use it when you want a deep integration inside your own product: authentication, conversation history, approvals, and streamed agent events. The app-server implementation is open source in the Codex GitHub repository ([openai/codex/codex-rs/app-server](https://github.com/openai/codex/tree/main/codex-rs/app-server)). See the [Open Source](https://developers.openai.com/codex/open-source) page for the full list of open-source Codex components.3Codex app-server is the interface Codex uses to power rich clients (for example, the Codex VS Code extension).

12Supported transports:12Supported transports:

13 13

14- `stdio` (`--listen stdio://`, default): newline-delimited JSON (JSONL).14- `stdio` (`--listen stdio://`, default): newline-delimited JSON (JSONL).

~~15- `websocket` (`--listen ws://IP:PORT`, experimental): one JSON-RPC message per WebSocket text frame.~~15- `websocket` (`--listen ws://IP:PORT`, experimental and unsupported): one

16 16 JSON-RPC message per WebSocket text frame.

17In WebSocket mode, app-server uses bounded queues. When request ingress is full, the server rejects new requests with JSON-RPC error code `-32001` and message `"Server overloaded; retry later."` Clients should retry with an exponentially increasing delay and jitter.17- Unix socket (`--listen unix://` or `--listen unix://PATH`): WebSocket

18 connections over Codex's default app-server control socket or a custom Unix

19 socket path, using the standard HTTP Upgrade handshake.

20- `off` (`--listen off`): don't expose a local transport.

22When you run with `--listen ws://IP:PORT`, the same listener also serves basic

23HTTP health probes:

25- `GET /readyz` returns `200 OK` once the listener accepts new connections.

26- `GET /healthz` returns `200 OK` when the request doesn't include an `Origin`

27 header.

28- Requests with an `Origin` header are rejected with `403 Forbidden`.

30WebSocket transport is experimental and unsupported. Local listeners such as

31`ws://127.0.0.1:PORT` are appropriate for localhost and SSH port-forwarding

32workflows. Non-loopback WebSocket listeners currently allow unauthenticated

33connections by default during rollout, so configure WebSocket auth before

34exposing one remotely.

36Supported WebSocket auth flags:

38- `--ws-auth capability-token --ws-token-file /absolute/path`

39- `--ws-auth capability-token --ws-token-sha256 HEX`

40- `--ws-auth signed-bearer-token --ws-shared-secret-file /absolute/path`

42For signed bearer tokens, you can also set `--ws-issuer`, `--ws-audience`, and

43`--ws-max-clock-skew-seconds`. Clients present the credential as

44`Authorization: Bearer <token>` during the WebSocket handshake, and app-server

45enforces auth before JSON-RPC `initialize`.

47Prefer `--ws-token-file` over passing raw bearer tokens on the command line. Use

48`--ws-token-sha256` only when the client keeps the raw high-entropy token in a

49separate local secret store; the hash is only a verifier, and clients still need

50the original token.

52In WebSocket mode, app-server uses bounded queues. When request ingress is full,

53the server rejects new requests with JSON-RPC error code `-32001` and message

54`"Server overloaded; retry later."` Clients should retry with an exponentially

55increasing delay and jitter.

56to define the action and provide tools and context. You can explicitly trigger a

57skill as part of an automation by using `$skill-name` inside your automation.

59## Ask Codex to create or update automations

61You can create and update automations from a regular Codex thread. Describe the

62task, the schedule, and whether the automation should stay attached to the

63current thread or start fresh runs. Codex can draft the automation prompt, choose

64the right automation type, and update it when the scope or cadence changes.

66For example, ask Codex to remind you in this thread while a deployment finishes,

67or ask it to create a standalone automation that checks a project on a recurring

68schedule.

70Skills can also create or update automations. For example, a skill for

71babysitting a pull request could set up a recurring automation that checks the

72PR status with the GitHub plugin and fixes new review feedback.

74## Thread automations

76Thread automations are heartbeat-style recurring wake-up calls attached to the

77current thread. Use them when you want Codex to keep returning to the same

78conversation on a schedule.

80Use a thread automation when the scheduled work should preserve the thread's

81context instead of starting from a new prompt each time.

83Thread automations can use minute-based intervals for active follow-up loops,

84or daily and weekly schedules when you need a check-in at a specific time.

86Thread automations are useful for:

88- checking a long-running command until it finishes

89- polling Slack, GitHub, or another connected source when the results should

90 stay in the same thread

91- reminding Codex to continue a review loop at a fixed cadence

92- running a skill-driven workflow that uses plugins, such as checking PR status

93 and addressing new feedback

94- keeping a chat focused on an ongoing research or triage task

96Use a standalone or project automation when each run should be independent,

97when it should run across more than one project, or when findings should appear

98as separate automation runs in Triage.

100When you create a thread automation, make the prompt durable. It should

101describe what Codex should do each time the thread wakes up, how to decide

102whether there is anything important to report, and when to stop or ask you for

103input.

1# In-app browser

3The in-app browser gives you and Codex a shared view of rendered web pages

4inside a thread. Use it when you're building or debugging a web app and want to

5preview pages and attach visual comments.

7Use it for local development servers, file-backed previews, and public pages

8that don't require sign-in. For anything that depends on login state or browser

9extensions, use your regular browser or the

10[Codex Chrome extension](https://developers.openai.com/codex/app/chrome-extension).

12Open the in-app browser from the toolbar, by clicking a URL, by navigating

13manually in the browser, or by pressing <kbd>Cmd</kbd>+<kbd>Shift</kbd>+<kbd>B</kbd>

14(<kbd>Ctrl</kbd>+<kbd>Shift</kbd>+<kbd>B</kbd> on Windows).

16The in-app browser does not support authentication flows, signed-in pages,

17 your regular browser profile, cookies, extensions, or existing tabs. Use it

18 for pages Codex can open without logging in.

20Treat page content as untrusted context. Don't paste secrets into browser flows.

30## Browser use

32Browser use lets Codex operate the in-app browser directly. Use it for local

33development servers and file-backed previews when Codex needs to click, type,

34inspect rendered state, take screenshots, or verify a fix in the page.

36To use it, install and enable the Browser plugin. Then ask Codex to use the

37browser in your task, or reference it directly with `@Browser`. The app keeps

38browser use inside the in-app browser and lets you manage allowed and blocked

39websites from settings.

41Example:

43```text

44Use the browser to open http://localhost:3000/settings, reproduce the layout

45bug, and fix only the overflowing controls.

46```

48Codex asks before using a website unless you've allowed it. Removing a site from

49the allowed list means Codex asks again before using it; removing a site from the

50blocked list means Codex can ask again instead of treating it as blocked.

52For signed-in websites in Chrome, see

53[Codex Chrome extension](https://developers.openai.com/codex/app/chrome-extension).

55## Preview a page

571. Start your app's development server in the [integrated terminal](https://developers.openai.com/codex/app/features#integrated-terminal) or with a [local environment action](https://developers.openai.com/codex/app/local-environments#actions).

582. Open an unauthenticated local route, file-backed page, or public page by

59 clicking a URL or navigating manually in the browser.

603. Review the rendered state alongside the code diff.

614. Leave browser comments on the elements or areas that need changes.

625. Ask Codex to address the comments and keep the scope narrow.

64Example feedback:

66```text

67I left comments on the pricing page in the in-app browser. Address the mobile

68layout issues and keep the card structure unchanged.

69```

71## Comment on the page

73When a bug is visible only in the rendered page, use browser comments to give

74Codex precise feedback on the page.

76- Turn on comment mode, select an element or area, and submit a comment.

77- In comment mode, hold <kbd>Shift</kbd> and click to select an area.

78- Hold <kbd>Cmd</kbd> while clicking to send a comment immediately.

80After you leave comments, send a message in the thread asking Codex to address

81them. Comments are most useful when Codex needs to make a precise visual change.

83Good feedback is specific:

85```text

86This button overflows on mobile. Keep the label on one line if it fits,

87otherwise wrap it without changing the card height.

88```

90```text

91This tooltip covers the data point under the cursor. Reposition the tooltip so

92it stays inside the chart bounds.

93```

95## Keep browser tasks scoped

97The in-app browser is for review and iteration. Keep each browser task small

98enough to review in one pass.

1# Codex Chrome extension

3The Codex Chrome extension lets Codex use Chrome for browser tasks that need

4your signed-in browser state. Use it when Codex needs to read or act on sites

5such as LinkedIn, Salesforce, Gmail, or internal tools.

7For local development servers, file-backed previews, and public pages that do

8not require sign-in, use the [in-app browser](https://developers.openai.com/codex/app/browser) first. The

9in-app browser keeps preview and verification work inside Codex without using

10your Chrome profile.

12Codex can also switch between tools as a task requires, using plugins when a

13dedicated integration is available, Chrome when it needs logged-in browser

14context, and the in-app browser for localhost.

18 client:load

19 color="warning"

20 variant="soft"

21 description="Treat page content as untrusted context, and review the website before allowing Codex to continue."

22 />

23</div>

25## Set up Chrome from Plugins

27Set up the extension from Codex:

291. Open Codex and go to **Plugins**.

302. Add the **Chrome** plugin.

313. Follow the setup flow. It guides you through installing the [Codex Chrome

32 extension](https://chromewebstore.google.com/detail/codex/hehggadaopoacecdllhhajmbjkdcmajg)

33 and approving Chrome's permission prompts.

344. Open Chrome and confirm the Codex extension shows **Connected**.

36After the plugin setup is complete, start a new Codex thread. Codex can suggest

37Chrome when a task needs a signed-in website. You can also invoke it directly in

38a prompt:

40```text

41@Chrome open Salesforce and update the account from these call notes.

42```

44If Chrome isn't already open, Codex can open it. Chrome browser tasks run in

45Chrome tab groups so the work for a thread stays grouped together.

47## Control website access

49By default, Codex asks before it interacts with each new website. Codex bases

50the prompt on the website host, such as `example.com`.

52When Codex asks to use a website, you can choose the option that matches the

53task and your risk tolerance:

55- Allow the website for the current chat.

56- Always allow the host so Codex can use that website again without asking.

57- Decline the website.

59### Manage the allowlist and blocklist

61In Computer Use settings, you can manage an allowlist and blocklist for

62domains. The allowlist contains domains Codex can use without asking again. The

63blocklist contains domains Codex shouldn't use.

65Removing a domain from the allowlist means Codex asks again before using it.

66Removing a domain from the blocklist means Codex can ask again instead of

67treating the domain as blocked.

69#### Always allow browser content <ElevatedRiskBadge class="ml-2" />

71If you turn on always allow browser content, Codex no longer asks for

72confirmation before using websites.

74#### Browser history <ElevatedRiskBadge class="ml-2" />

76Browser history can include sensitive telemetry, internal URLs, search terms,

77and activity from Chrome sessions on signed-in devices. If you allow Codex to

78access browser history, relevant history entries can become part of the context

79Codex uses for the task. Malicious or misleading page content can increase the

80risk that Codex copies this data somewhere unintended.

82Codex asks when it wants to use browser history. Codex scopes history access to

83the request, and history doesn't have an always-allow option.

85## Data and security

87### Chrome extension permissions

89Chrome asks you to accept extension permissions when you install the extension.

90The permission prompt may include:

92- Access the page debugger

93- Read and change all your data on all websites

94- Read and change your browsing history on all your signed-in devices

95- Display notifications

96- Read and change your bookmarks

97- Manage your downloads

98- Communicate with cooperating native applications

99- View and manage your tab groups

100

101These Chrome permissions make the extension capable of operating browser

102workflows. Codex still uses its own confirmations, settings, allowlists, and

103blocklists before using websites or browser history during a task.

104

105### Memories

106

107Browser use follows your Codex Memories setting. If Memories is on, Codex can

108use relevant saved memories while working in Chrome. If Memories is off, browser

109use doesn't use memories.

110

111### What OpenAI stores from browsing

112

113OpenAI doesn't store a separate complete record of your Chrome actions from the

114extension. OpenAI stores browser activity only when it becomes part of the Codex

115context, such as text Codex reads from a page, screenshots, tool calls,

116summaries, messages, or other content included in the thread.

117

118Your ChatGPT and Codex data controls apply to content processed in context.

119Avoid sending secrets or highly sensitive data through browser tasks unless

120they're required and you are present to review each prompt.

121

122## Troubleshooting

123

124If Codex can't connect to Chrome, first confirm the website Codex is trying to

125access isn't in the blocklist in Settings. If the website isn't blocked, work

126through these checks:

127

1281. Open the Codex extension from the Chrome toolbar or Chrome's extensions

129 menu. Make sure it shows **Connected**. If it shows disconnected or mentions

130 a missing native host, remove and re-add the Chrome plugin from **Plugins**

131 in Codex, then follow the setup flow again.

1322. In Codex, open **Plugins** and confirm that the Chrome plugin is on. If the

133 plugin is off, turn it on and try the task again.

1343. Make sure you are using the same Chrome profile where the Codex extension is

135 installed. If you use more than one Chrome profile, install and enable the

136 extension in the active profile.

1374. Start a new Codex thread and try the Chrome task again. This can clear a

138 thread-specific connection state.

1395. Restart Chrome and Codex, then try again. If the extension still doesn't

140 connect, uninstall the Codex Chrome extension, remove and re-add the Chrome

141 plugin from **Plugins**, and follow the setup flow again.

1426. If the extension shows **Connected** but Codex still can't use Chrome, run

143 `/feedback` in the Codex app and include the thread ID when you contact

144 support.

154### Upload Files

155

156If a Chrome task needs to upload a file from your computer, allow the Codex

157extension to access file URLs in Chrome:

158

1591. In Chrome, open the extensions icon in the toolbar, then click **Manage

160 Extensions**.

1612. On the Codex extension card, click **Details**.

1623. Turn on **Allow access to file URLs**.

163

164After you change the setting, start the Chrome task again.

Details

1# Computer Use

3In the Codex app, computer use is currently available on macOS, except in the

4 European Economic Area, the United Kingdom, and Switzerland at launch. Install

5 the Computer Use plugin, then grant Screen Recording and Accessibility

6 permissions when macOS prompts you.

8With computer use, Codex can see and operate graphical user interfaces on macOS.

9Use it for tasks where command-line tools or structured integrations aren't

10enough, such as checking a desktop app, using a browser, changing app settings,

11working with a data source that isn't available as a plugin, or reproducing a

12bug that only happens in a graphical user interface.

14Because computer use can affect app and system state outside your project

15workspace, use it for scoped tasks and review permission prompts before

16continuing.

18## Set up computer use

20In Codex settings, open **Computer Use** and click **Install** to install the

21Computer Use plugin before you ask Codex to operate desktop apps. When macOS

22prompts for access, grant Screen Recording and Accessibility permissions if you

23want Codex to see and interact with the target app.

25To use computer use, grant:

27- **Screen Recording** permission so Codex can see the target app.

28- **Accessibility** permission so Codex can click, type, and navigate.

30## When to use computer use

32Choose computer use when the task depends on a graphical user interface that's

33hard to verify through files or command output alone.

35Good fits include:

37- Testing a macOS app, an iOS simulator flow, or another desktop app that Codex

38 is building.

39- Performing a task that requires your web browser.

40- Reproducing a bug that only appears in a graphical interface.

41- Changing app settings that require clicking through a UI.

42- Inspecting information in an app or data source that isn't available through a

43 plugin.

44- Running a scoped task in the background while you keep working elsewhere.

45- Executing a workflow that spans more than one app.

47For web apps you are building locally, use the

48[in-app browser](https://developers.openai.com/codex/app/browser) first.

50## Start a computer use task

52Mention `@Computer` or `@AppName` in your prompt, or ask Codex to use

53computer use. Describe the exact app, window, or flow Codex should operate.

55```text

56Open the app with computer use, reproduce the onboarding bug, and fix the

57smallest code path that causes it. After each change, run the same UI flow

58again.

59```

61```text

62Open @Chrome and verify the checkout page still works after the latest changes.

63```

65If the target app exposes a dedicated plugin or MCP server, prefer that

66structured integration for data access and repeatable operations. Choose

67computer use when Codex needs to inspect or operate the app visually.

69## Permissions and approvals

71The macOS system permissions for computer use are separate from app approvals in

72Codex. The macOS permissions let Codex see and operate apps. App approvals

73determine which apps you allow Codex to use. File reads, file edits, and shell

74commands still follow the sandbox and approval settings for the thread.

76With computer use, Codex can see and take action only in the apps you allow.

77During a task, Codex asks for your permission before it can use an app on your

78computer. You can choose **Always allow** so Codex can use that app in the future

79without asking again. You can remove apps from the **Always allow** list in the

80**Computer Use** section of Codex settings.

82<CodexScreenshot

83 alt="Codex app asking for permission to use Calculator with computer use"

84 lightSrc="/images/codex/app/computer-use-approval-light.webp"

85 darkSrc="/images/codex/app/computer-use-approval-dark.webp"

86 maxHeight="420px"

87 variant="no-wallpaper"

88/>

90Codex may also ask for permission before taking sensitive or disruptive actions.

92If Codex can't see or control an app, open **System Settings > Privacy &

93Security** and check **Screen Recording** and **Accessibility** for the Codex

94app.

96## Safety guidance

98With computer use, Codex can view screen content, take screenshots, and interact

99with windows, menus, keyboard input, and clipboard state in the target app.

100Treat visible app content, browser pages, screenshots, and files opened in the

101target app as context Codex may process while the task runs.

102

103Keep tasks narrow and stay present for sensitive flows:

104

105- Give Codex one clear target app or flow at a time.

106- You can stop the task or take over your computer at any time.

107- Keep sensitive apps closed unless they're required for the task.

108- Avoid tasks that require secrets unless you're present and can approve each

109 step.

110- Review app permission prompts before allowing Codex to use an app.

111- Use **Always allow** only for apps you trust Codex to use automatically in

112 future tasks.

113- Stay present for account, security, privacy, network, payment, or

114 credential-related settings.

115- Cancel the task if Codex starts interacting with the wrong window.

116

117If Codex uses your browser, it can interact with pages where you're already

118signed in. Review website actions as if you were taking them yourself: web pages

119can contain malicious or misleading content, and sites may treat approved clicks,

120form submissions, and signed-in actions as coming from your account. To keep

121using your browser while Codex works, ask Codex to use a different browser.

122

123The feature can't automate terminal apps or Codex itself, since automating them

124could bypass Codex security policies. It also can't authenticate as an

125administrator or approve security and privacy permission prompts on your

126computer.

127

128File edits and shell commands still follow Codex approval and sandbox settings

129where applicable. Changes made through desktop apps may not appear in the review

130pane until they're saved to disk and tracked by the project. Your ChatGPT data

131controls apply to content processed through Codex, including screenshots taken

132by computer use.

277## In-app browser

278

279Use the [in-app browser](https://developers.openai.com/codex/app/browser) to preview, review, and comment on

280local development servers, file-backed previews, and public pages that don't

281require sign-in while you iterate on a web app.

282

283The in-app browser doesn't support authentication flows, signed-in pages, your

284regular browser profile, cookies, extensions, or existing tabs.

285

286Use browser comments to mark specific elements or areas on a page, then ask

287Codex to address that feedback.

288

289When you want Codex to operate the page directly, use

290[browser use](https://developers.openai.com/codex/app/browser#browser-use) for local development servers and

291file-backed pages. You can manage the Browser plugin, allowed websites, and

292blocked websites from settings.

310## Computer use

311

312[Computer use](https://developers.openai.com/codex/app/computer-use) helps Codex operate a macOS app by

313seeing, clicking, and typing. This is useful for testing desktop apps, checking

314browser or simulator flows, working with data sources that aren't available as

315plugins, changing app settings, and reproducing GUI-only bugs.

316

317Because computer use can affect app and system state outside your project

318workspace, keep tasks narrow and review permission prompts before continuing.

319

320The feature isn't available in the European Economic Area, the United Kingdom, or

321Switzerland at launch.

343## Work with non-code artifacts

344

345When a task produces non-code artifacts, the sidebar can preview PDF files,

346spreadsheets, documents, and presentations. Give Codex the source data, expected

347file type, structure, and review criteria you care about.

348

349For spreadsheets and presentations, describe the sheets, columns, charts, slide

350sections, and checks that matter. Ask Codex to explain where it saved the output

351and how it checked the result.

352

353Use the task sidebar to follow what Codex is doing while a thread runs. It can

354surface the agent's plan, sources, generated artifacts, and task summary so you

355can steer the work, inspect generated files, and decide what needs another pass.

385## Thread automations

386

387Automations can also attach to a single thread. These thread automations are

388recurring wake-up calls that preserve the thread's context so Codex can check

389on long-running work, poll a source for new information, or continue a follow-up

390loop. Use them for heartbeat-style automations that should keep returning to the

391same conversation on a schedule.

392

393Use a thread automation when the next run depends on the current conversation.

394Use a standalone or project [automation](https://developers.openai.com/codex/app/automations) when you want

439## Image generation

440

441Ask Codex to generate or edit images directly in a thread. This is useful for UI assets, banners, backgrounds, illustrations, sprite sheets, and placeholders you want to create alongside code. Add a reference image when you want Codex to transform or extend an existing asset.

442

443You can ask in natural language or explicitly invoke the image generation skill by including `$imagegen` in your prompt.

444

445Built-in image generation uses `gpt-image-2`, counts toward your general Codex usage limits, and uses included limits 3-5x faster on average than similar turns without image generation, depending on image quality and size. For details, see [Pricing](https://developers.openai.com/codex/pricing#image-generation-usage-limits). For prompting tips and model details, see the [image generation guide](https://developers.openai.com/api/docs/guides/image-generation).

446

447For larger batches of image generation, set `OPENAI_API_KEY` in your environment variables and ask Codex to generate images through the API so API pricing applies instead.

459## Chats

460

461Chats are threads you can start when the task doesn't need a specific project

462folder or Git repository. Use them for research, triage, planning,

463plugin-heavy workflows, and other conversations where Codex should use connected

464tools instead of editing a codebase.

465

466Chats use a Codex-managed `threads` directory under your Codex home as their

467working location. By default, that location is `~/.codex/threads`.

469## Memories

471[Memories](https://developers.openai.com/codex/memories), where available, let Codex carry useful context

65## Pull request reviews

67When Codex has GitHub access for your repository and the current project is on

68the pull request branch, the Codex app can help you work through pull request

69feedback without leaving the app. The sidebar shows pull request context and

70feedback from reviewers, and the review pane shows comments alongside the diff

71so you can ask Codex to address issues in the same thread.

73Install the GitHub CLI (`gh`) and authenticate it with `gh auth login` so Codex

74can load pull request context, review comments, and changed files. If `gh` is

75missing or unauthenticated, pull request details may not appear in the sidebar

76or review pane.

78Use this flow when you want to keep the full fix loop in one place:

801. Open the review pane on the pull request branch.

812. Review the pull request context, comments, and changed files.

823. Ask Codex to fix the specific comments you want handled.

834. Inspect the resulting diff in the review pane.

845. Stage, commit, and push the changes to the PR branch when you are ready.

86### How Codex manages worktrees for you121### How Codex manages worktrees for you

87 122

88Codex creates worktrees in `$CODEX_HOME/worktrees`. The starting commit will be the `HEAD` commit of the branch selected when you start your thread. If you chose a branch with local changes, the uncommitted changes will be applied to the worktree as well. The worktree will *not* be checked out as a branch. It will be in a [detached HEAD](https://git-scm.com/docs/git-checkout#_detached_head) state. This lets Codex create several worktrees without polluting your branches.123Codex creates worktrees in `$CODEX_HOME/worktrees`.

101 136

102Why this limitation exists137<ToggleSection title="Why this limitation exists">

~~103~~

104Git prevents the same branch from being checked out in more than one worktree at a time because a branch represents a single mutable reference (`refs/heads/<name>`) whose meaning is “the current checked-out state” of a working tree.138Git prevents the same branch from being checked out in more than one worktree at a time because a branch represents a single mutable reference (`refs/heads/<name>`) whose meaning is “the current checked-out state” of a working tree.

105 139

106When a branch is checked out, Git treats its HEAD as owned by that worktree and expects operations like commits, resets, rebases, and merges to advance that reference in a well-defined, serialized way. Allowing multiple worktrees to simultaneously check out the same branch would create ambiguity and race conditions around which worktree’s operations update the branch reference, potentially leading to lost commits, inconsistent indexes, or unclear conflict resolution.140When a branch is checked out, Git treats its HEAD as owned by that worktree and expects operations like commits, resets, rebases, and merges to advance that reference in a well-defined, serialized way.

107 141

108By enforcing a one-branch-per-worktree rule, Git guarantees that each branch has a single authoritative working copy, while still allowing other worktrees to safely reference the same commits via detached HEADs or separate branches.142By enforcing a one-branch-per-worktree rule, Git guarantees that each branch has a single authoritative working copy, while still allowing other worktrees to safely reference the same commits via detached HEADs or separate branches.

~~63For access from another machine, bind the app server to a reachable interface, for example:~~65For access from another machine, bind the app server to a reachable interface

64 66and configure WebSocket auth before remote use:

~~65```bash~~

~~66codex app-server --listen ws://0.0.0.0:4500~~

~~67```~~

69`--remote` accepts explicit `ws://host:port` and `wss://host:port` addresses only. For plain WebSocket connections, prefer local-host addresses or SSH port forwarding. If you expose the listener beyond the local host, configure authentication before real remote use and put authenticated non-local connections behind TLS.

~~71Codex supports these WebSocket authentication modes for remote TUI connections:~~

73- **No WebSocket auth**: Best for local-host listeners or SSH port-forwarded connections. Codex can start non-local listeners without auth, but logs a warning and the startup banner reminds you to configure auth before real remote use.

74- **Capability token**: Store a shared token in a file on the app-server host, start the server with `--ws-auth capability-token --ws-token-file /abs/path/to/token`, then set the same token in an environment variable on the TUI host and pass `--remote-auth-token-env <ENV_VAR>`.

75- **Signed bearer token**: Store an HMAC shared secret in a file on the app-server host, start the server with `--ws-auth signed-bearer-token --ws-shared-secret-file /abs/path/to/secret`, and have the TUI send a signed JWT bearer token through `--remote-auth-token-env <ENV_VAR>`. The shared secret must be at least 32 bytes. Signed tokens use HS256 and must include `exp`; Codex also validates `nbf`, `iss`, and `aud` when those claims or server options are present.

~~77To create a capability token on the app-server host, generate a random token file with permissions that only your user can read:~~

78 67

79```bash68```bash

~~80TOKEN_FILE="$HOME/.codex/codex-app-server-token"~~69TOKEN_FILE="$HOME/.codex/app-server-token"

~~86Treat the token file like a password, and regenerate it if it leaks.~~75`--remote` accepts explicit `ws://host:port` and `wss://host:port` addresses.

76Plain WebSocket connections are appropriate for localhost and SSH

77port-forwarding workflows. For non-local clients, use WebSocket auth and put the

78connection behind TLS.

87 79

~~88Then start the app server with that token file. For example, with a capability token behind a TLS proxy:~~80Codex supports these WebSocket authentication modes:

82- Capability token: start the server with `--ws-auth capability-token` and

83 either `--ws-token-file /absolute/path` or `--ws-token-sha256 HEX`.

84- Signed bearer token: start the server with

85 `--ws-auth signed-bearer-token --ws-shared-secret-file /absolute/path`, plus

86 optional `--ws-issuer`, `--ws-audience`, and `--ws-max-clock-skew-seconds`.

88The TUI sends the remote auth token as an `Authorization: Bearer <token>` header

89during the WebSocket handshake. Codex only accepts remote auth tokens over

90`wss://` URLs or loopback `ws://` URLs.

89 91

90```bash92```bash

~~91# Remote host~~93export CODEX_REMOTE_TOKEN="$(cat "$TOKEN_FILE")"

~~92TOKEN_FILE="$HOME/.codex/codex-app-server-token"~~94codex --remote wss://remote-host:4500 --remote-auth-token-env CODEX_REMOTE_TOKEN

102```95```

103 96

104The TUI sends remote auth tokens as `Authorization: Bearer <token>` during the WebSocket handshake. Codex only sends those tokens over `wss://` URLs or `ws://` URLs whose host is `localhost`, `127.0.0.1`, or `::1`, so put non-local remote listeners behind TLS if clients need to authenticate over the network.97For SSH remote projects in the Codex app, use

98[Remote connections](https://developers.openai.com/codex/remote-connections). For managed remote-control

99clients, `codex remote-control` starts an app-server process with

100remote-control support enabled.

153## Image generation

154

155Ask Codex to generate or edit images directly in the CLI. This works well for assets such as icons, banners, illustrations, sprite sheets, and placeholder art. If you want Codex to transform or extend an existing asset, attach a reference image with your prompt.

156

157You can ask in natural language or explicitly invoke the image generation skill by including `$imagegen` in your prompt.

158

159Built-in image generation uses `gpt-image-2`, counts toward your general Codex usage limits, and uses included limits 3-5x faster on average than similar turns without image generation, depending on image quality and size. For details, see [Pricing](https://developers.openai.com/codex/pricing#image-generation-usage-limits). For prompting tips and model details, see the [image generation guide](https://developers.openai.com/api/docs/guides/image-generation).

160

161For larger batches of image generation, set `OPENAI_API_KEY` in your environment variables and ask Codex to generate images through the API so API pricing applies instead.

978Details883This page catalogs every documented Codex CLI command and flag. Use the interactive tables to search by key or description. Each section indicates whether the option is stable or experimental and calls out risky combinations.

979 884

980Use the local open source provider (requires a running Ollama instance).885The CLI inherits most defaults from <code>~/.codex/config.toml</code>. Any

886 <code>-c key=value</code> overrides you pass at the command line take

887 precedence for that invocation. See [Config

888 basics](https://developers.openai.com/codex/config-basic#configuration-precedence) for more information.

983 891

984`--output-last-message, -o`892<ConfigTable client:load options={globalFlagOptions} />

985 893

986Type / Values894These options apply to the base `codex` command and propagate to each subcommand unless a section below specifies otherwise.

895When you run a subcommand, place global flags after it (for example, `codex exec --oss ...`) so Codex applies them as intended.

990Details899The Maturity column uses feature maturity labels such as Experimental, Beta,

900 and Stable. See [Feature Maturity](https://developers.openai.com/codex/feature-maturity) for how to

996`--output-schema`912### `codex` (interactive)

997 913

998Type / Values914Running `codex` with no subcommand launches the interactive terminal UI (TUI). The agent accepts the global flags above plus image attachments. Web search defaults to cached mode; use `--search` to switch to live browsing. For low-friction local work, use `--sandbox workspace-write --ask-for-approval on-request`.

999 915

1000`path`916Use `--remote ws://host:port` or `--remote wss://host:port` to connect the TUI to an app server started with `codex app-server --listen ws://IP:PORT`. Add `--remote-auth-token-env <ENV_VAR>` when the server requires a bearer token for WebSocket authentication.

1001 917

1002Details918### `codex app-server`

1003 919

1004JSON Schema file describing the expected final response shape. Codex validates tool output against it.920Launch the Codex app server locally. This is primarily for development and debugging and may change without notice.

1006Key922<ConfigTable client:load options={appServerOptions} />

1007 923

1008`--profile, -p`924`codex app-server --listen stdio://` keeps the default JSONL-over-stdio behavior. `--listen ws://IP:PORT` enables WebSocket transport for app-server clients. The server accepts `ws://` listen URLs; use TLS termination or a secure proxy when clients connect with `wss://`. Use `--listen unix://` to accept WebSocket handshakes on Codex's default Unix socket, or `--listen unix:///absolute/path.sock` to choose a socket path. If you generate schemas for client bindings, add `--experimental` to include gated fields and methods.

1# Auto-review

3Auto-review replaces manual approval at the sandbox boundary with a separate

4reviewer agent. The main Codex agent still runs inside the same sandbox, with

5the same approval policy and the same network and filesystem limits. The

6difference is who reviews eligible escalation requests.

8Auto-review only applies when approvals are interactive. In practice, that

9 means `approval_policy = "on-request"` or a granular approval policy that

10 still surfaces the relevant prompt category. With `approval_policy = "never"`,

11 there is nothing to review.

13## How auto-review works

15At a high level, the flow is:

171. The main agent works inside `read-only` or `workspace-write`.

182. When it needs to cross the sandbox boundary, it requests approval.

193. If `approvals_reviewer = "auto_review"`, Codex routes that approval request

20 to a separate reviewer agent instead of stopping for a person.

214. The reviewer decides whether the action should run and returns a rationale.

225. If the action is approved, execution continues. If it is denied, the main

23 agent is instructed to find a materially safer path or stop and ask the

24 user.

26Auto-review is a reviewer swap, not a permission grant. It does not expand

27`writable_roots`, enable network access, or weaken protected paths. It only

28changes how Codex handles actions that already need approval.

30## When it triggers

32Auto-review evaluates approval requests that would otherwise pause for a human.

33These include:

35- Shell or exec tool calls that request escalated sandbox permissions.

36- Network requests blocked by the current sandbox or policy.

37- File edits outside the allowed writable roots.

38- MCP or app tool calls that require approval based on their tool annotations

39 or configured approval mode.

40- Browser Use access to a new website or domain.

42Auto-review does not run for routine actions already allowed inside the

43sandbox. If a command can run under the active `sandbox_mode`, or a tool call

44stays within the allowed policy, the main agent continues without review.

46Computer Use is a separate case. App approvals for Computer Use still surface

47directly to the user, so Auto-review does not replace those app-level prompts.

49## What auto-review blocks

51At a high level, Auto-review is designed to block actions such as:

53- sending private data, secrets, or credentials to untrusted destinations

54- probing for credentials, tokens, cookies, or session material

55- broad or persistent security weakening

56- destructive actions with significant risk of irreversible damage

58The exact policy lives in the open-source Codex repository:

59[policy_template.md](https://github.com/openai/codex/blob/main/codex-rs/core/src/guardian/policy_template.md)

60and

61[policy.md](https://github.com/openai/codex/blob/main/codex-rs/core/src/guardian/policy.md).

62That policy can be customized per enterprise with `guardian_policy_config` or

63per user with local [`[auto_review].policy`](/codex/config-advanced#approval-policies-and-sandbox-modes).

65## What the reviewer sees

67The reviewer is itself a Codex agent with a narrower job than the main agent:

68decide whether a specific boundary-crossing action should run.

70The reviewer sees a compact transcript plus the exact approval request. That

71typically includes user messages, surfaced assistant updates, relevant tool

72calls and tool outputs, and the action now being proposed for approval. It can

73also perform read-only checks to gather missing context, but it does so rarely.

75Hidden assistant reasoning is not included. Auto-review sees retained

76conversation items and tool evidence, not private chain-of-thought.

78## Denials and failure behavior

80An explicit denial is not treated like an ordinary sandbox error. Codex returns

81the review rationale to the main agent and adds a stronger instruction:

83- Do not pursue the same outcome via workaround, indirect execution, or policy

84 circumvention.

85- Continue only with a materially safer alternative.

86- Otherwise, stop and ask the user.

88Codex also applies a rejection circuit breaker per turn. In the current

89open-source implementation, Auto-review interrupts the turn after `3`

90consecutive denials or `10` denials within a rolling window of the last `50`

91reviews in the same turn.

93Any non-denial resets the consecutive-denial counter. When the breaker trips,

94Codex emits a warning and aborts the current turn with an interrupt rather than

95letting the agent loop on more escalation attempts.

97Timeouts are surfaced separately from explicit denials, and the main agent is

98informed that a timeout alone is not proof that the action is unsafe.

100There is also an explicit override path for denied actions. In the current

101open-source TUI, run `/approve` to open the **Auto-review Denials** picker, then

102select one recent denied action to approve for one retry. Codex records up to 10

103recent denials per thread. That approval is narrow: it applies to the exact

104denied action, not similar future actions; it is recorded for one retry in the

105same context; and the retry still goes through Auto-review. Under the hood,

106Codex injects a developer-scoped approval marker for that exact action. The

107reviewer then sees that explicit user override as context, but it still follows

108policy and can deny again if policy says the user cannot overwrite that class of

109denial.

110

111## Configuration

112

113For setup details, see

114[Managed configuration](https://developers.openai.com/codex/enterprise/managed-configuration#configure-automatic-review-policy).

115

116The default reviewer policy is in the open-source Codex repository:

117[core/src/guardian/policy.md](https://github.com/openai/codex/blob/main/codex-rs/core/src/guardian/policy.md).

118Enterprises can replace its tenant-specific section with

119`guardian_policy_config` in managed requirements. Individual users can also set

120a local

121[`[auto_review].policy`](/codex/config-advanced#approval-policies-and-sandbox-modes)

122in their `config.toml`, but managed requirements take precedence:

123

124```toml

125[auto_review]

126policy = """

127YOUR POLICY GOES HERE

128"""

129```

130

131To customize the policy, copy the whole default policy wording first, then

132iterate based on your individual risk profile.

133

134## Reduce review volume without weakening security

135

136Auto-review works best when the sandbox already covers your common safe

137workflows. If too many mundane actions need review, fix the boundary first

138instead of teaching the reviewer to approve noisy escalations forever.

139

140In practice, the highest-leverage changes are:

141

142- Add narrow

143 [`writable_roots`](https://developers.openai.com/codex/config-advanced#approval-policies-and-sandbox-modes)

144 for scratch directories or neighboring repos you intentionally use.

145- Add narrowly scoped [prefix rules](https://developers.openai.com/codex/rules). Prefer precise command

146 prefixes such as `["cargo", "test"]` or `["pnpm", "run", "lint"]` over broad

147 patterns such as `["python"]` or `["curl"]`. Broad rules often erase the very

148 boundary Auto-review is meant to guard.

149

150Auto-review session transcripts are retained under `~/.codex/sessions` by

151default, so you can ask Codex to analyze past traffic there before changing

152policy or permissions.

153

154## Limits

155

156Auto-review improves the default operating point for long-running agentic work,

157but it is not a deterministic security guarantee.

158

159- It only evaluates actions that ask to cross a boundary.

160- It can still make mistakes, especially in adversarial or unusual contexts.

161- It should complement, not replace, good sandbox design, monitoring, and

162 organization-specific policy.

~~91## Hooks (experimental)~~91Project config files can't override settings that redirect credentials, change

92provider auth, or run machine-local notification/telemetry commands.

93Codex ignores the following keys in project-local `.codex/config.toml` and

94prints a startup warning when it sees them: `openai_base_url`,

95`chatgpt_base_url`, `model_provider`, `model_providers`, `notify`, `profile`,

96`profiles`, `experimental_realtime_ws_base_url`, and `otel`. Set those keys in

97your user-level `~/.codex/config.toml` instead.

104In practice, the four most useful locations are:

97 105

98- `~/.codex/hooks.json`106- `~/.codex/hooks.json`

107- `~/.codex/config.toml`

99- `<repo>/.codex/hooks.json`108- `<repo>/.codex/hooks.json`

109- `<repo>/.codex/config.toml`

110

111Project-local hooks load only when the project `.codex/` layer is trusted.

112User-level hooks remain independent of project trust.

200### Amazon Bedrock provider

201

202Codex includes a built-in `amazon-bedrock` model provider. Set it directly as

203`model_provider`; unlike custom providers, this built-in provider supports only

204the nested AWS profile and region overrides.

205

206```toml

207model_provider = "amazon-bedrock"

208model = "<bedrock-model-id>"

209

210[model_providers.amazon-bedrock.aws]

211profile = "default"

212region = "eu-central-1"

213```

214

215If you omit `profile`, Codex uses the standard AWS credential chain. Set

216`region` to the supported Bedrock region that should handle requests.

231You can also use a granular approval policy (`approval_policy = { granular = { ... } }`) to allow or auto-reject individual prompt categories.

307### Named permission profiles

308

309Set `default_permissions` to reuse a sandbox profile by name. Codex includes

310the built-in profiles `:read-only`, `:workspace`, and `:danger-no-sandbox`:

311

312```toml

313default_permissions = ":workspace"

314```

315

316For custom profiles, point `default_permissions` at a name you define under

317`[permissions.<name>]`:

318

319```toml

320default_permissions = "workspace"

321

322[permissions.workspace.filesystem]

323":project_roots" = { "." = "write", "**/*.env" = "none" }

328mode = "limited"

329

330[permissions.workspace.network.domains]

331"api.openai.com" = "allow"

332```

333

334Use built-in names with a leading colon. Custom names don't use a leading

335colon and must have matching `permissions` tables.

1# Access tokens

3Codex access tokens let trusted automation run Codex local with a ChatGPT workspace identity. Use them when a script, scheduled job, or CI runner needs repeatable, non-interactive Codex access.

5Codex access tokens are currently supported for ChatGPT Business and

6 Enterprise workspaces.

8Access tokens are created in the ChatGPT admin console at [Access tokens](https://chatgpt.com/admin/access-tokens). They are tied to the ChatGPT user and workspace that create them, and Codex uses them as agent identities for programmatic local workflows.

10If a Platform API key works for your automation, keep using API key auth. Use

11 Codex access tokens when the workflow specifically needs ChatGPT workspace

12 access, ChatGPT-managed Codex entitlements, or enterprise workspace controls.

14## How access tokens work

16Use an access token when Codex needs to run without a user completing a browser sign-in. The token represents the ChatGPT workspace user who created it, so runs can use that user's Codex access and appear in workspace governance data.

18Codex checks the token when a run starts and ties the run to that workspace identity. Treat the token like any other automation secret: store it in a secret manager, keep it out of logs, and rotate it regularly.

20Use access tokens for:

22- `codex exec` jobs that run from trusted automation.

23- Local scripts that need repeatable, non-interactive Codex runs.

24- Enterprise workflows where usage should be associated with a ChatGPT workspace user instead of an API organization key.

26Main risks to avoid:

28- **Leaked secrets:** anyone with the token can start Codex runs as the token creator. Store tokens in a secret manager, keep them out of logs, and rotate them regularly.

29- **Untrusted runners:** public CI, forked pull requests, or shared machines can expose tokens to people outside your workspace. Use access tokens only on trusted runners.

30- **Shared identities:** one person's token reused across unrelated teams makes ownership and audit trails harder to interpret. Create tokens for a specific workflow owner.

31- **Stale credentials:** long-lived tokens can remain active after the workflow changes. Prefer finite expirations and revoke tokens that are no longer used.

32- **Wrong credential type:** access tokens are for Codex local workflows. Use Platform API keys for general OpenAI API calls.

34## Enable access token creation

36Use the Codex Local controls in workspace settings to turn on access token creation for allowed members.

41 darkSrc="/images/codex/enterprise/rbac_access_token_access_permission_dark.png"

42 maxWidth={847}

43 variant="no-wallpaper"

44/>

461. Go to [Workspace Settings > Settings and Permissions](https://chatgpt.com/admin/settings).

472. In the Codex Local section, make sure **Allow members to use Codex Local** is turned on.

483. Turn on **Allow members to use Codex access tokens** if all allowed members should be able to create access tokens.

494. If you use custom roles for a narrower rollout, assign the access token permission only to groups that need to create tokens.

51Keep access token creation limited to people or service owners who understand where the token will be stored, which automation will use it, and how it will be rotated.

53## Create an access token

55Use the Access tokens page to name the token and choose when it expires.

571. Go to [Access tokens](https://chatgpt.com/admin/access-tokens).

582. Select **Create**.

60<CodexScreenshot

61 alt="Access tokens page with the Create button"

63 darkSrc="/images/codex/enterprise/access_token_create_header_dark.png"

64 maxWidth={942}

65 variant="no-wallpaper"

66/>

683. Enter a descriptive name, such as `release-ci` or `nightly-docs-check`.

70<CodexScreenshot

71 alt="Create access token modal with fields for name and expiration"

73 darkSrc="/images/codex/enterprise/access_token_creation_modal_dark.png"

74 maxWidth={544}

75 variant="no-wallpaper"

76/>

784. Choose an expiration. Prefer a finite expiration such as 7, 30, 60, or 90 days. If you choose **No expiration**, rotate the token on a regular schedule.

795. Select **Create**.

806. Copy the generated access token immediately. You cannot view it again after you close the modal.

817. Store the token in your secret manager or CI secret store.

83The shortest custom expiration is one day. Revoked and expired tokens cannot be used to start new Codex runs.

85## Use an access token with Codex CLI

87For ephemeral automation, store the token in `CODEX_ACCESS_TOKEN` and run Codex normally:

89```bash

90export CODEX_ACCESS_TOKEN="<access-token>"

91codex exec --json "review this repository and summarize the top risks"

92```

94For a persistent local login, pipe the token to `codex login --with-access-token`:

96```bash

97printf '%s' "$CODEX_ACCESS_TOKEN" | codex login --with-access-token

98codex exec "summarize the last release diff"

99```

100

101`codex login --with-access-token` stores an agent identity credential in Codex auth storage. If you prefer not to persist credentials on the machine, use the `CODEX_ACCESS_TOKEN` environment variable instead.

102

103## Rotate or revoke a token

104

105Rotate access tokens the same way you rotate other automation secrets:

106

1071. Create a replacement token.

1082. Update the secret in the runner, scheduler, or secret manager.

1093. Run a smoke test with the new token.

1104. Revoke the old token from [Access tokens](https://chatgpt.com/admin/access-tokens).

111

112From the Access tokens page, workspace owners and admins can revoke any workspace token. Members with access token permission can revoke only the tokens they created.

113

114## Permission model

115

116Access token permissions are separate from the general Codex local permission. A member can have access to the Codex app, CLI, or IDE extension without being allowed to create access tokens.

117

119| ------------------------------------------------------------- | ---------------------------------------------------- | --------------------------------------------- | -------------------------------------- |

120| Open [Access tokens](https://chatgpt.com/admin/access-tokens) | Yes | Yes | No |

121| Create access tokens | Yes, for their own ChatGPT workspace identity | Yes, for their own ChatGPT workspace identity | No |

122| List access tokens | Workspace list, including who created each token | Only tokens they created | No |

124| Grant or remove access token permission | Yes | No | No |

125| Manage other Codex enterprise settings | Yes, based on admin role and Codex admin permissions | No, unless separately granted | No |

126

127In short: workspace owners and admins manage access at the workspace level. Members need the access token permission to create and manage their own tokens, but the permission does not grant admin rights or access to other members' tokens.

128

129## Troubleshooting

130

131### The access tokens page returns 404 or forbidden

132

133Ask a workspace owner or admin to confirm that Codex access tokens are enabled and that your role includes the access token permission.

134

135### `codex login --with-access-token` fails

136

137Confirm that you copied the generated access token, not a browser session token or Platform API key. Also confirm that the token has not expired or been revoked.

75### Override sandbox requirements by host

77Use `[[remote_sandbox_config]]` when one managed policy should apply different

78sandbox requirements on different hosts. For example, you can keep a stricter

79default for laptops while allowing workspace writes on matching dev boxes or CI

80runners. Host-specific entries currently override `allowed_sandbox_modes` only:

82```toml

83allowed_sandbox_modes = ["read-only"]

85[[remote_sandbox_config]]

86hostname_patterns = ["*.devbox.example.com", "runner-??.ci.example.com"]

87allowed_sandbox_modes = ["read-only", "workspace-write"]

88```

90Codex compares each `hostname_patterns` entry against the best-effort resolved

91host name. It prefers the fully qualified domain name when available and falls

92back to the local host name. Matching is case-insensitive; `*` matches any

93sequence of characters, and `?` matches one character.

95The first matching `[[remote_sandbox_config]]` entry wins within the same

96requirements source. If no entry matches, Codex keeps the top-level

97`allowed_sandbox_modes`. Host name matching is for policy selection only; don't

98treat it as authenticated device proof.

75You can also constrain web search mode:100You can also constrain web search mode:

~~84You can also pin [feature flags](https://developers.openai.com/codex/config-basic/#feature-flags):~~109### Configure network access requirements

110

111Use `[experimental_network]` in `requirements.toml` when administrators should

112define network access requirements centrally. These requirements are separate

113from the user `features.network_proxy` toggle: they can configure sandboxed

114networking without that feature flag, but they do not grant command network

115access when the active sandbox keeps networking off.

85 116

117```toml

118experimental_network.enabled = true

119experimental_network.dangerously_allow_all_unix_sockets = true

120experimental_network.allow_local_binding = true

121experimental_network.allowed_domains = [

125experimental_network.denied_domains = [

126 "blocked.example.com",

127 "*.exfil.example.com",

128]

86```129```

130

131Use `experimental_network.managed_allowed_domains_only = true` only when you

132also define administrator-owned `allowed_domains` and want that allowlist to be

133exclusive. If it is `true` without managed allow rules, user-added domain allow

134rules do not remain effective.

135

136The domain syntax, local/private destination rules, deny-over-allow behavior,

137and DNS rebinding limitations are the same as the sandboxed networking behavior

138described in [Agent approvals & security](https://developers.openai.com/codex/agent-approvals-security#network-isolation).

160- `in_app_browser = false` disables the in-app browser pane.

161- `browser_use = false` disables Browser Use and Browser Agent availability.

162- `computer_use = false` disables Computer Use availability and related

163 install or setup flows.

164

165If omitted, these features are allowed by policy, subject to normal client,

166platform, and rollout availability.

167

168### Configure automatic review policy

169

170Use `allowed_approvals_reviewers` to require or allow automatic review. Set it

171to `["auto_review"]` to require automatic review, or include `"user"` when users

172can choose manual approval.

173

174Set `guardian_policy_config` to replace the tenant-specific section of the

175automatic review policy. Codex still uses the built-in reviewer template and

176output contract. Managed `guardian_policy_config` takes precedence over local

177`[auto_review].policy`.

178

179```toml

180allowed_approval_policies = ["on-request"]

181allowed_approvals_reviewers = ["auto_review"]

182

183guardian_policy_config = """

184## Environment Profile

185- Trusted internal destinations include github.com/my-org, artifacts.example.com,

186 and internal CI systems.

187

188## Tenant Risk Taxonomy and Allow/Deny Rules

189- Treat uploads to unapproved third-party file-sharing services as high risk.

190- Deny actions that expose credentials or private source code to untrusted

191 destinations.

192"""

193```

194

195### Enforce deny-read requirements

196

197Admins can deny reads for exact paths or glob patterns with

198`[permissions.filesystem]`. Users can't weaken these requirements with local

199configuration.

200

201```toml

202[permissions.filesystem]

203deny_read = [

204 "/Users/alice/.ssh",

205 "./private/**/*.txt",

206]

207```

208

209When deny-read requirements are present, Codex constrains local sandbox mode to

210`read-only` or `workspace-write` so Codex can enforce them. On native

211Windows, managed `deny_read` applies to direct file tools; shell subprocess

212reads don't use this sandbox rule.

213

214### Enforce managed hooks from requirements

215

216Admins can also define managed lifecycle hooks directly in `requirements.toml`.

217Use `[hooks]` for the hook configuration itself, and point `managed_dir` at the

218directory where your MDM or endpoint-management tooling installs the referenced

219scripts.

220

221To enforce managed hooks even for users who disabled hooks locally, pin

222`[features].hooks = true` alongside `[hooks]`.

223

224```toml

225[features]

226hooks = true

227

228[hooks]

229managed_dir = "/enterprise/hooks"

230windows_managed_dir = 'C:\enterprise\hooks'

231

232[[hooks.PreToolUse]]

233matcher = "^Bash$"

234

235[[hooks.PreToolUse.hooks]]

236type = "command"

237command = "python3 /enterprise/hooks/pre_tool_use_policy.py"

238timeout = 30

239statusMessage = "Checking managed Bash command"

240```

241

242Notes:

243

244- Codex enforces the hook configuration from `requirements.toml`, but it does

245 not distribute the scripts in `managed_dir`.

246- Deliver those scripts separately with your MDM or device-management solution.

247- Managed hook commands should reference absolute script paths under the

248 configured managed directory.

249

244This shift doesn’t require a radical overhaul; small, targeted workflows compound quickly as coding agents become more capable and reliable. Teams that start with well-scoped tasks, invest in guardrails, and iteratively expand agent responsibility see meaningful gains in speed, consistency, and developer focus.252This shift doesn’t require a radical overhaul; small, targeted workflows compound quickly as coding agents become more capable and reliable.

31## Where Codex looks for hooks35## Where Codex looks for hooks

32 36

~~33Codex discovers `hooks.json` next to active config layers.~~37Codex discovers hooks next to active config layers in either of these forms:

39- `hooks.json`

40- inline `[hooks]` tables inside `config.toml`

34 41

~~35In practice, the two most useful locations are:~~42Installed plugins can also bundle lifecycle config through their plugin

43manifest or a default `hooks/hooks.json` file. See [Build

44plugins](https://developers.openai.com/codex/plugins/build#bundled-mcp-servers-and-lifecycle-config) for the

45plugin packaging rules.

47In practice, the four most useful locations are:

36 48

37- `~/.codex/hooks.json`49- `~/.codex/hooks.json`

50- `~/.codex/config.toml`

38- `<repo>/.codex/hooks.json`51- `<repo>/.codex/hooks.json`

52- `<repo>/.codex/config.toml`

54If more than one hook source exists, Codex loads all matching hooks.

55Higher-precedence config layers don't replace lower-precedence hooks.

56If a single layer contains both `hooks.json` and inline `[hooks]`, Codex

57merges them and warns at startup. Prefer one representation per layer.

59Plugin hooks are off by default in this release. If

60`[features].plugin_hooks = true`, Codex can also discover hooks bundled with

61enabled plugins. Otherwise, enabled plugins won't run bundled hooks.

39 62

~~40If more than one `hooks.json` file exists, Codex loads all matching hooks.~~63Project-local hooks load only when the project `.codex/` layer is trusted. In

~~41Higher-precedence config layers do not replace lower-precedence hooks.~~64untrusted projects, Codex still loads user and system hooks from their own

65active config layers.

67## Review and manage hooks

69Codex lists configured hooks before deciding which ones can run. Use `/hooks`

70in the CLI to inspect hook sources, review new or changed hooks, trust hooks, or

71disable individual non-managed hooks. If hooks need review at startup, Codex

72prints a warning that tells you to open `/hooks`.

74Managed hooks from system, MDM, cloud, or `requirements.toml` sources are marked

75as managed, trusted by policy, and can't be disabled from the user hook browser.

194statusMessage = "Reviewing Bash output"

195```

196

197## Managed hooks from `requirements.toml`

198

199Enterprise-managed requirements can also define hooks inline under `[hooks]`.

200This is useful when admins want to enforce the hook configuration while

201delivering the actual scripts through MDM or another device-management system.

202To enforce managed hooks even for users who disabled hooks locally, pin

203`[features].hooks = true` in `requirements.toml` alongside `[hooks]`.

204

205```toml

206[features]

207hooks = true

208

209[hooks]

210managed_dir = "/enterprise/hooks"

211windows_managed_dir = 'C:\enterprise\hooks'

212

213[[hooks.PreToolUse]]

214matcher = "^Bash$"

215

216[[hooks.PreToolUse.hooks]]

217type = "command"

218command = "python3 /enterprise/hooks/pre_tool_use_policy.py"

219timeout = 30

220statusMessage = "Checking managed Bash command"

221```

222

223Notes for managed hooks:

224

225- `managed_dir` is used on macOS and Linux.

226- `windows_managed_dir` is used on Windows.

227- Codex doesn't distribute the scripts in `managed_dir`; your enterprise

228 tooling must install and update them separately.

229- Managed hook commands should use absolute script paths under the configured

230 managed directory.

231

232## Plugin-bundled hooks

233

234Plugin-bundled hooks are opt-in for this release. When

235`[features].plugin_hooks = true` and a plugin is enabled, Codex can load

236lifecycle hooks from that plugin alongside user, project, and managed hooks.

237

238```toml

239[features]

240plugin_hooks = true

241```

242

243By default, Codex looks for `hooks/hooks.json` inside the plugin root. A plugin

244manifest can override that default with a `hooks` entry in

245`.codex-plugin/plugin.json`. The manifest entry can be a `./`-prefixed path, an

246array of `./`-prefixed paths, an inline hooks object, or an array of inline

247hooks objects.

248

249```json

250{

251 "name": "repo-policy",

252 "hooks": "./hooks/hooks.json"

253}

254```

255

256Manifest hook paths are resolved relative to the plugin root and must stay

257inside that root. If a manifest defines `hooks`, Codex uses those manifest

258entries instead of the default `hooks/hooks.json`.

259

260Plugin hook commands receive these environment variables:

261

262- `PLUGIN_ROOT` is a Codex-specific extension that points to the installed

263 plugin root.

264- `PLUGIN_DATA` is a Codex-specific extension that points to the plugin's

265 writable data directory.

266- Codex also sets `CLAUDE_PLUGIN_ROOT` and `CLAUDE_PLUGIN_DATA` for

267 compatibility with existing plugin hooks.

268

269Plugin hooks use the same event schema as other hooks. They are non-managed

270hooks, so they require trust review before they run.

271

126## Matcher patterns272## Matcher patterns

127 273

128The `matcher` field is a regex string that filters when hooks fire. Use `"*"`,274The `matcher` field is a regex string that filters when hooks fire. Use `"*"`,

451### PermissionRequest

452

453`PermissionRequest` runs when Codex is about to ask for approval, such as a

454shell escalation or managed-network approval. It can allow the request, deny

455the request, or decline to decide and let the normal approval prompt continue.

456It doesn't run for commands that don't need approval.

457

458`matcher` is applied to `tool_name` and matcher aliases. Current canonical

459values include `Bash`, `apply_patch`, and MCP tool names such as

502

503If multiple matching hooks return decisions, any `deny` wins. Otherwise, an

504`allow` lets the request proceed without surfacing the approval prompt. If no

505matching hook decides, Codex uses the normal approval flow.

91## Image generation

93Ask Codex to generate or edit images without leaving your editor. This is useful for UI assets, layouts, illustrations, sprite sheets, and quick placeholders while you work. Add a reference image to the prompt when you want Codex to transform or extend an existing asset.

95You can ask in natural language or explicitly invoke the image generation skill by including `$imagegen` in your prompt.

97Built-in image generation uses `gpt-image-2`, counts toward your general Codex usage limits, and uses included limits 3-5x faster on average than similar turns without image generation, depending on image quality and size. For details, see [Pricing](https://developers.openai.com/codex/pricing#image-generation-usage-limits). For prompting tips and model details, see the [image generation guide](https://developers.openai.com/api/docs/guides/image-generation).

99For larger batches of image generation, set `OPENAI_API_KEY` in your environment variables and ask Codex to generate images through the API so API pricing applies instead.

1# Memories

3Memories are off by default and aren't available in the European Economic

4 Area, the United Kingdom, or Switzerland at launch. Enable them in Codex

5 settings, or set `memories = true` in the `[features]` table in

6 `~/.codex/config.toml`.

8Memories let Codex carry useful context from earlier threads into future work.

9After you enable memories, Codex can remember stable preferences, recurring

10workflows, tech stacks, project conventions, and known pitfalls so you don't

11need to repeat the same context in every thread.

13Keep required team guidance in `AGENTS.md` or checked-in documentation. Treat

14memories as a helpful local recall layer, not as the only source for rules that

15must always apply.

17[Chronicle](https://developers.openai.com/codex/memories/chronicle) helps Codex recover recent working

18context from your screen to build up memory.

20## Enable memories

22In the Codex app, enable Memories in settings.

24For config-based setup, add the feature flag to `config.toml`:

26```toml

27[features]

28memories = true

29```

31See [Config basics](https://developers.openai.com/codex/config-basic) for where Codex stores user-level

32configuration and how Codex loads `~/.codex/config.toml`.

34## How memories work

36After you enable memories, Codex can turn useful context from eligible prior

37threads into local memory files. Codex skips active or short-lived sessions,

38redacts secrets from generated memory fields, and updates memories in the

39background instead of immediately at the end of every thread.

41Memories may not update right away when a thread ends. Codex waits until a

42thread has been idle long enough to avoid summarizing work that's still in

43progress.

45Memory generation can also skip a background pass when your Codex rate-limit

46remaining percentage is below the configured threshold, so Codex doesn't spend

47quota when you're near a limit.

49## Memory storage

51Codex stores memories under your Codex home directory. By default, that's

52`~/.codex`. See [Config and state locations](https://developers.openai.com/codex/config-advanced#config-and-state-locations)

53for how Codex uses `CODEX_HOME`.

55The main memory files live under `~/.codex/memories/` and include summaries,

56durable entries, recent inputs, and supporting evidence from prior threads.

58Treat these files as generated state. You can inspect them when troubleshooting

59or before sharing your Codex home directory, but don't rely on editing them by

60hand as your primary control surface.

62## Control memories per thread

64In the Codex app and Codex TUI, use `/memories` to control memory behavior for

65the current thread. Thread-level choices let you decide whether the current

66thread can use existing memories and whether Codex can use the thread to

67generate future memories.

69Thread-level choices don't change your global memory settings.

71## Configuration

73Enable memories in the Codex app settings, or set `memories = true` in the

74`[features]` section of `config.toml`.

76For config file locations and the full list of memory-related settings, see the

77[configuration reference](https://developers.openai.com/codex/config-reference).

79Common memory-specific settings include:

81- `memories.generate_memories`: controls whether newly created threads can be

82 stored as memory-generation inputs.

83- `memories.use_memories`: controls whether Codex injects existing memories into

84 future sessions.

85- `memories.disable_on_external_context`: when `true`, keeps threads that used

86 external context such as MCP tool calls, web search, or tool search out of

87 memory generation. The older `memories.no_memories_if_mcp_or_web_search` key

88 is still accepted as an alias.

89- `memories.min_rate_limit_remaining_percent`: controls the minimum remaining

90 Codex rate-limit percentage required before memory generation starts.

91- `memories.extract_model`: overrides the model used for per-thread memory

92 extraction.

93- `memories.consolidation_model`: overrides the model used for global memory

94 consolidation.

96## Review memories

98Don't store secrets in memories. Codex redacts secrets from generated memory

99fields, but you should still review memory files before sharing your Codex home

100directory or generated memory artifacts.

1# Chronicle

3Chronicle is in an **opt-in research preview**. It is only available for

4 ChatGPT Pro subscribers on macOS, and is not yet available in the EU, UK and

5 Switzerland. Please review the [Privacy and Security](#privacy-and-security)

6 section for details and to understand the current risks before enabling.

8Chronicle augments Codex memories with context from your screen. When you prompt

9Codex, those memories can help it understand what you’ve been working on with

10less need for you to restate context.

12Chronicle is available as an opt-in research preview in the Codex app on macOS.

13It requires macOS Screen Recording and Accessibility permissions. Before

14enabling, be aware that Chronicle uses rate limits quickly, increases risk of

15prompt injection, and stores memories unencrypted on your device.

17## How Chronicle helps

19We’ve designed Chronicle to reduce the amount of context you have to restate

20when you work with Codex. By using recent screen context to improve memory

21building, Chronicle can help Codex understand what you’re referring to, identify

22the right source to use, and pick up on the tools and workflows you rely on.

24<section class="feature-grid mt-4">

26<div>

28### Use what’s on screen

30With Chronicle Codex can understand what you are currently looking at, saving

31you time and context switching.

33</div>

35<ChronicleThreadDemo client:load scenario="screen" />

37</section>

39<section class="feature-grid inverse">

41<div>

43### Fill in missing context

45No need to carefully craft your context and start from zero. Chronicle lets

46Codex fill in the gaps in your context.

48</div>

50<ChronicleThreadDemo client:load scenario="project" />

52</section>

54<section class="feature-grid">

56<div>

58### Remember tools and workflows

60No need to explain to Codex which tools to use to perform your work. Codex

61learns as you work to save you time in the long run.

63</div>

65<ChronicleThreadDemo client:load scenario="tools" />

67</section>

69In these cases, Codex uses Chronicle to provide additional context. When another

70source is better for the job, such as reading the specific file, Slack thread,

71Google Doc, dashboard, or pull request, Codex uses Chronicle to identify the

72source and then use that source directly.

74## Enable Chronicle

761. Open Settings in the Codex app.

772. Go to **Personalization** and make sure **Memories** is enabled.

783. Turn on **Chronicle** below the Memories setting.

794. Review the consent dialog and choose **Continue**.

805. Grant macOS Screen Recording and Accessibility permissions when prompted.

816. When setup completes, choose **Try it out** or start a new thread.

83If macOS reports that Screen Recording or Accessibility permission is denied,

84open System Settings > Privacy & Security > Screen Recording or

85Accessibility and enable Codex. If a permission is restricted by macOS or your

86organization, Chronicle will start after the restriction is removed and Codex

87receives the required permission.

89## Pause or disable Chronicle at any time

91You control when Chronicle generates memories using screen context. Use the

92Codex menu bar icon to choose **Pause Chronicle** or **Resume Chronicle**. Pause

93Chronicle before meetings or when viewing sensitive content that you do not want

94Codex to use as context. To disable Chronicle, return to **Settings >

95Personalization > Memories** and turn off **Chronicle**.

97You can also control whether memories are used in a given thread. [Learn

98more](https://developers.openai.com/codex/memories#control-memories-per-thread).

100## Rate limits

101

102Chronicle works by running sandboxed agents in the background to generate

103memories from captured screen images. These agents currently consume rate limits

104quickly.

105

106## Privacy and security

107

108Chronicle uses screen captures, which can include sensitive information visible

109on your screen. It does not have access to your microphone or system audio.

110Don’t use Chronicle to record meetings or communications with others without

111their consent. Pause Chronicle when viewing content you do not want remembered

112in memories.

113

114### Where does Chronicle store my data?

115

116Screen captures are ephemeral and will only be saved temporarily on your

117computer. Temporary screen capture files may appear under

118`$TMPDIR/chronicle/screen_recording/` while Chronicle is running. Screen captures

119that are older than 6 hours will be deleted while Chronicle is running.

120

121The memories that Chronicle generates are just like other Codex memories:

122unencrypted markdown files that you can read and modify if needed. You can also

123ask Codex to search them. If you want to have Codex forget something you can

124delete the respective file inside the folder or selectively edit the markdown

125files to remove the information you’d like to remove. You should not manually

126add new information. The generated Chronicle memories are stored locally on your

127computer under `$CODEX_HOME/memories_extensions/chronicle/` (typically

128`~/.codex/memories_extensions/chronicle`).

129

130<div className="not-prose my-4">

131 <Alert

132 client:load

133 color="danger"

134 variant="soft"

135 description="Both directories for your screen captures and memories might contain sensitive information. Make sure you do not share content with others, and be aware that other programs on your computer can also access these files."

136 />

137</div>

138

139### What data gets shared with OpenAI?

140

141Chronicle captures screen context locally, then periodically uses Codex to

142summarize recent activity into memories. To generate those memories, Chronicle

143starts an ephemeral Codex session with access to this screen context. That

144session may process selected screenshot frames, OCR text extracted from

145screenshots, timing information, and local file paths for the relevant time

146window.

147

148Screen captures used for memory generation are stored temporarily on your device. They are processed on our

149servers to generate memories, which are then stored locally on device. We do not

150store the screenshots on our servers after processing unless required by law,

151and do not use them for training.

152

153The generated memories are Markdown files stored locally under

154`$CODEX_HOME/memories_extensions/chronicle/`. When Codex uses memories in a

155future session, relevant memory contents may be included as context for that

156session, and may be used to improve our models if allowed in your ChatGPT

157settings. [Learn more](https://help.openai.com/en/articles/7730893-data-controls-faq).

158

159## Prompt injection risk

160

161Using Chronicle increases risk to prompt injection attacks from screen content.

162For instance, if you browse a site with malicious agent instructions, Codex may

163follow those instructions.

164

165## Troubleshooting

166

167### How do I enable Chronicle?

168

169If you do not see the Chronicle setting, make sure you are using a Codex app

170build that includes Chronicle and that you have Memories enabled inside Settings

171> Personalization.

172

173Chronicle is currently only available for ChatGPT Pro subscribers on macOS.

174Chronicle is not available in the EU, UK and Switzerland.

175

176If setup does not complete:

177

1781. Confirm that Codex has Screen Recording and Accessibility permissions.

1792. Quit and reopen the Codex app.

1803. Open **Settings > Personalization** and check the Chronicle status.

181

182### Which model is used for generating the Chronicle memories?

183

184Chronicle uses the same model as your other [Memories](https://developers.openai.com/codex/memories). If you

185did not configure a specific model it uses your default Codex model. To choose a

186specific model, update the `consolidation_model` in your

187[configuration](https://developers.openai.com/codex/config-basic).

188

189```toml

190[memories]

191consolidation_model = "gpt-5.4-mini"

1# Migrate to Codex

3Use the import flow to bring your instructions, configuration, skills, MCP

4servers, hooks, subagents, and recent sessions from another agent into Codex.

5Codex migrates the parts it can handle directly and can open a follow-up thread

6to help migrate anything that remains.

14 class="p-3 sm:p-4"

15 imageClass="rounded-xl"

16 />

17</div>

19## Start the migration

21<WorkflowSteps>

231. Open **Settings** in the Codex app.

242. On the **General** page, find **Import other agent setup**.

253. Select **Import** or **Import again**.

264. Review what Codex found, choose what to bring over, then select **Import**.

275. After the import finishes, select **View imported files** if you want to inspect the result.

29</WorkflowSteps>

31## How migration works

33Codex checks both your user-level setup and the current project. User-level

34setup comes from files on your machine; project-level setup comes from files in

35the repository you have open.

37When you import, Codex:

391. Detects the setup it can find.

402. Imports the selected items it can migrate directly.

413. Checks again after the import finishes.

424. Offers to continue the migration in a new thread if anything still needs

43 follow-up work.

45## What Codex can import

47| Detected setup | Codex destination |

48| ------------------------------------- | -------------------------------------- |

49| Instruction files | [`AGENTS.md`](https://developers.openai.com/codex/guides/agents-md) |

50| `settings.json` | [`config.toml`](https://developers.openai.com/codex/config-basic) |

51| Skills | [Codex skills](https://developers.openai.com/codex/skills) |

52| Recent sessions from the last 30 days | Codex threads and projects |

53| MCP server configuration | [Codex MCP configuration](https://developers.openai.com/codex/mcp) |

54| Hooks | [Codex hooks](https://developers.openai.com/codex/hooks) |

55| Slash commands | [Codex skills](https://developers.openai.com/codex/skills) |

56| Subagents | [Codex agents](https://developers.openai.com/codex/subagents) |

58## Finish remaining setup in a new thread

60Some detected setup does not have a clean one-to-one mapping into Codex. For

61those items, Codex can open a new thread with the

62[`migrate-to-codex`](https://github.com/openai/skills/tree/main/skills/.curated/migrate-to-codex)

63skill to help finish the migration.

65When that happens, Codex shows the remaining setup and offers **Continue in

66Codex**.

68<div class="not-prose my-6 max-w-4xl">

69 <CodexScreenshot

70 alt="Additional setup found after import"

73 maxHeight="520px"

74 class="p-6 sm:p-8"

75 imageClass="!w-auto rounded-xl"

76 />

77</div>

79If you continue, Codex opens a new thread with the remaining work already filled

80in. The thread keeps user-level setup separate from project-level setup so you

81can see where each remaining item belongs.

83<div class="not-prose my-6 max-w-4xl">

88 maxHeight="320px"

89 class="p-6 sm:p-8"

90 imageClass="rounded-xl"

91 />

92</div>

94## What to review after import

96Review any migrated setup before you rely on it, especially:

98- Tool restrictions or permissions in imported skills and agents.

99- MCP server settings that use custom authentication, headers, environment

100 variables, or transports.

101- Hooks whose behavior may differ in Codex.

102- Plugins, marketplaces, or other remaining setup that needs manual follow-up.

103- Prompt templates or command-style prompts that depend on arguments, shell

104 interpolation, or file-path placeholders.

105

106## After you switch

107

108Once the import finishes, open one of your migrated projects and continue from

109there. If you are new to Codex, see the [quickstart](https://developers.openai.com/codex/quickstart) for the

110rest of the setup flow.

205For most tasks in Codex, start with `gpt-5.5` when it appears in your model

206 picker. It is strongest for complex coding, computer use, knowledge work, and

207 research workflows. GPT-5.5 is currently available in Codex when you sign in

208 with ChatGPT or API-key authentication. Use `gpt-5.4-mini` when you want a

209 faster, lower-cost option for lighter coding tasks or subagents. The

57Use `codex plugin marketplace add` when you want Codex to install and track a

58marketplace source for you instead of editing `config.toml` by hand.

60```bash

61codex plugin marketplace add owner/repo

62codex plugin marketplace add owner/repo --ref main

63codex plugin marketplace add https://github.com/example/plugins.git --sparse .agents/plugins

64codex plugin marketplace add ./local-marketplace-root

65```

67Marketplace sources can be GitHub shorthand (`owner/repo` or

68`owner/repo@ref`), HTTP or HTTPS Git URLs, SSH Git URLs, or local marketplace root

69directories. Use `--ref` to pin a Git ref, and repeat `--sparse PATH` to use a

70sparse checkout for Git-backed marketplace repos. `--sparse` is valid only for

71Git marketplace sources.

73To refresh or remove configured marketplaces:

75```bash

76codex plugin marketplace upgrade

77codex plugin marketplace upgrade marketplace-name

78codex plugin marketplace remove marketplace-name

496### Bundled MCP servers and lifecycle hooks

497

498`mcpServers` can point to an `.mcp.json` file that contains either a direct

499server map or a wrapped `mcp_servers` object.

500

501Direct server map:

502

503```json

504{

505 "docs": {

506 "command": "docs-mcp",

507 "args": ["--stdio"]

508 }

509}

510```

511

512Wrapped server map:

513

514```json

515{

516 "mcp_servers": {

517 "docs": {

518 "command": "docs-mcp",

519 "args": ["--stdio"]

520 }

521 }

522}

523```

524

525After installation, users can enable or disable a bundled MCP server and tune

526tool approval policy from their Codex config without editing the plugin. Use

527`plugins.<plugin>.mcp_servers.<server>` for plugin-scoped MCP server policy:

528

529```toml

530[plugins."my-plugin".mcp_servers.docs]

531enabled = true

532default_tools_approval_mode = "prompt"

533enabled_tools = ["search"]

534

535[plugins."my-plugin".mcp_servers.docs.tools.search]

536approval_mode = "approve"

537```

538

539Plugin hooks are off by default in this release. When

540`[features].plugin_hooks = true` and your plugin is enabled, Codex can load

541lifecycle hooks from your plugin alongside user, project, and managed hooks.

542

543```toml

544[features]

545plugin_hooks = true

546```

547

548The default plugin hook file is `hooks/hooks.json`:

549

550```json

551{

552 "hooks": {

553 "SessionStart": [

554 {

555 "hooks": [

556 {

557 "type": "command",

558 "command": "python3 ${PLUGIN_ROOT}/hooks/session_start.py",

559 "statusMessage": "Loading plugin context"

560 }

561 ]

562 }

563 ]

564 }

565}

566```

567

568If you define `hooks` in `.codex-plugin/plugin.json`, Codex uses that manifest

569entry instead of the default `hooks/hooks.json`. The manifest field can be a

570single path, an array of paths, an inline hooks object, or an array of inline

571hooks objects.

572

573```json

574{

575 "name": "repo-policy",

576 "hooks": ["./hooks/session.json", "./hooks/tools.json"]

577}

578```

579

580Hook paths follow the same manifest path rules as `skills`, `apps`, and

581`mcpServers`: start with `./`, resolve relative to the plugin root, and stay

582inside the plugin root.

583

584Plugin hook commands receive the Codex-specific environment variables

585`PLUGIN_ROOT` and `PLUGIN_DATA`. `PLUGIN_ROOT` points to the installed plugin

586root, and `PLUGIN_DATA` points to the plugin's writable data directory. Codex

587also sets `CLAUDE_PLUGIN_ROOT` and `CLAUDE_PLUGIN_DATA` for compatibility with

588existing plugin hooks.

589

590Plugin hooks use the same event schema as regular hooks. See

591[Hooks](https://developers.openai.com/codex/hooks) for supported events, inputs, outputs, trust review, and

592current limitations.

35- **Cloud threads** run in an isolated [environment](https://developers.openai.com/codex/cloud/environments). Codex clones your repository and checks out the branch it's working on. Cloud threads are useful when you want to run work in parallel or delegate tasks from another device. To use cloud threads with your repo, push your code to GitHub first.

37In the Codex app, you can also start a chat without choosing a project. Chats

38aren't tied to a saved repository or project folder. Use them for research,

39planning, connected-tool workflows, or other work where Codex shouldn't start

40from a codebase. Chats use a Codex-managed `threads` directory under your Codex

41home as their working location. By default, that location is `~/.codex/threads`.

42To change the base location for this state, set `CODEX_HOME`; see

43[Config and state locations](https://developers.openai.com/codex/config-advanced#config-and-state-locations).

1# Remote connections

3import {

4 Desktop,

5 Storage,

6 Terminal,

7} from "@components/react/oai/platform/ui/Icon.react";

9Remote connections let you use Codex from another device or another machine.

10Use Codex in the ChatGPT mobile app to work with Codex on a connected Mac,

11continue work from another Codex App device, or connect the Codex App to

12projects on an SSH host.

14Remote access uses the connected host's projects, threads, files, credentials,

15permissions, plugins, Computer Use, browser setup, and local tools.

17## What you can do remotely

19- Start new threads in projects on the host, or continue existing ones.

20- Send follow-up instructions, answer questions, and steer active work.

21- Approve commands and other actions.

22- Review outputs, diffs, test results, terminal output, and screenshots.

23- Get notified when Codex completes a task or needs your attention.

24- Switch between connected hosts and threads.

26The next sections cover using Codex in the ChatGPT mobile app to control a Codex

27App host. To connect Codex to a project on an SSH host, see

28[connect to an SSH host](#connect-to-an-ssh-host).

39</div>

41## Before you set up mobile access

43Make sure you have:

45- Codex access in the ChatGPT account and workspace you want to use.

46- The latest ChatGPT mobile app on an iOS or Android device. If you do not see

47 Codex in the ChatGPT mobile app, update ChatGPT first.

48- The latest Codex App for macOS running on a Mac host that is awake, online,

49 and signed in to the same account and workspace. Mobile setup starts from the

50 Codex App; you cannot set it up from the Codex CLI or IDE Extension.

51- Any required multi-factor authentication, SSO, or passkey configuration for

52 that account or workspace.

54If you use Codex through a ChatGPT workspace, your admin may need to enable

55Remote Control access before you can connect from your phone.

57## Set up mobile access

59Start in the Codex App on the host you want to connect. The setup flow enables

60remote access for that host, then shows a QR code you can scan from your phone.

62<WorkflowSteps variant="headings">

641. Start Codex mobile setup.

66 Open Codex on the host and select **Set up Codex mobile** in the

67 sidebar.

692. Scan the QR code.

71 Use your phone to scan the QR code shown by Codex. The code opens ChatGPT so

72 you can finish connecting the mobile app to the host.

743. Finish setup in ChatGPT.

76 ChatGPT opens the Codex mobile setup flow. Confirm the same ChatGPT account

77 and workspace, then complete any required multi-factor authentication, SSO,

78 or passkey steps. After setup succeeds, the host appears in Codex on your

79 phone.

814. Review host settings.

83 In Codex on the host, use **Settings > Connections** to manage connected

84 devices. You can also choose whether to keep the computer awake, enable

85 Computer Use, or install the Chrome extension.

98</div>

100## Choose what to connect

101

102Start with the Mac laptop or desktop where you already use Codex. Add an

103always-on Mac or SSH host when you need continuous access or a different

104environment.

105

106### <span class="not-prose inline-flex items-center gap-3 align-middle"><span class="inline-flex h-7 w-7 shrink-0 items-center justify-center rounded-md bg-surface-secondary text-secondary"><Desktop width={17} height={17} /></span><span>Your Mac laptop or desktop</span></span>

107

108Connect the Mac where you already run Codex day to day. This gives remote access

109to the same projects, threads, credentials, plugins, and local setup you already

110use.

111

112If that Mac sleeps, loses network access, or closes Codex, remote access stops

113until it is available again. If you use this computer as your host device, keep

114it plugged in and turn on **Keep this Mac awake** in the host's connection

115settings.

116

117On a Mac laptop, remote access can stay available with the lid open while the

118computer is plugged in. With the lid closed, connect an external display as

119well. Choosing **Sleep** still stops remote access.

120

121### <span class="not-prose inline-flex items-center gap-3 align-middle"><span class="inline-flex h-7 w-7 shrink-0 items-center justify-center rounded-md bg-surface-secondary text-secondary"><Storage width={17} height={17} /></span><span>A dedicated always-on Mac</span></span>

122

123Use a dedicated always-on Mac when you want Codex to stay reachable for

124longer-running work.

125

126Install the projects, credentials, plugins, MCP servers, and tools Codex should

127use on that machine.

128

129### <span class="not-prose inline-flex items-center gap-3 align-middle"><span class="inline-flex h-7 w-7 shrink-0 items-center justify-center rounded-md bg-surface-secondary text-secondary"><Terminal width={17} height={17} /></span><span>A remote development environment</span></span>

130

131Use an SSH host or managed devbox when the project already lives in a remote

132environment. Connect the Codex App host to that environment first; your phone

133still connects to the Codex App host, and Codex works in the remote environment

134with its dependencies, security policies, and compute resources.

135

136For SSH setup details, see [connect to an SSH host](#connect-to-an-ssh-host).

137

138For browser or desktop tasks on an always-on Mac or remote host, enable

139 Computer Use and install the Chrome extension on that host.

140

141## What comes from the connected host

142

143Your phone sends prompts, approvals, and follow-up messages to Codex. The

144connected host provides the environment Codex uses.

145

146That means:

147

148- Repository files and local documents come from the connected host.

149- Shell commands run on that host or remote environment.

150- Any plugin installed on that host is available when you use Codex remotely.

151- MCP servers, skills, browser access, and Computer Use come from that host's

152 configuration.

153- Signed-in websites and desktop apps are available only when the host can

154 access them.

155- Sandboxing, security controls, and action approvals still apply to the

156 connected session.

157

158Codex uses a secure relay layer to keep trusted machines reachable across your

159authorized ChatGPT devices without exposing them directly to the public

160internet.

161

162## Pick up work from another device

163

164You can continue work from another signed-in Codex App device. For example, if

165your laptop is unavailable, you can start a thread from your phone on an

166always-on host, then later open Codex on your laptop and continue that same

167thread there.

168

169In Codex on the laptop, use **Settings > Connections > Control other devices**

170to add the other host. A device can allow remote access and control another

171device at the same time.

183

184## Connect to an SSH host

185

186In the Codex App, add remote projects from an SSH host and run threads against

187the remote filesystem and shell. Remote project threads run commands, read

188files, and write changes on the remote host.

189

190Keep the remote host configured with the same security expectations you use for

191normal SSH access: trusted keys, least-privilege accounts, and no

192unauthenticated public listeners.

193

194<WorkflowSteps variant="headings">

195

1961. Add the host to your SSH config so Codex can auto-discover it.

197

198 ```text

199 Host devbox

200 HostName devbox.example.com

201 User you

202 IdentityFile ~/.ssh/id_ed25519

203 ```

204

205 Codex reads concrete host aliases from `~/.ssh/config`, resolves them with

206 OpenSSH, and ignores pattern-only hosts.

207

2082. Confirm you can SSH to the host from the machine running the Codex App.

209

210 ```bash

211 ssh devbox

212 ```

213

2143. Install and authenticate Codex on the remote host.

215

216 The app starts the remote Codex app server through SSH, using the remote

217 user's login shell. Make sure the `codex` command is available on the

218 remote host's `PATH` in that shell.

219

2204. In the Codex App, open **Settings > Connections**, add or enable the SSH

221 host, then choose a remote project folder.

231 imageClass="rounded-xl"

232/>

233

234## Authentication and network exposure

235

236Remote connections use SSH to start and manage the remote Codex app server.

237Don't expose app-server transports directly on a shared or public network.

238

239If you need to reach a remote machine outside your current network, use a VPN

240or mesh networking tool instead of exposing the app server directly to the

241internet.

242

243## Troubleshooting

To avoid crowding out the rest of the prompt, this list is capped at roughly 2% of the model’s context window, or 8,000 characters when the context window is unknown.

70## Introduction

72When you are building an AI application, or making changes to an existing one, you want to make sure it behaves as expected. Evals are a way to systematically test a set of scenarios and catch regressions before they ship.

74You can use Promptfoo to run evals on your AI application, and Codex to help you create and maintain the evals.

76## How to use

78Use Codex with the Promptfoo plugin's `$promptfoo-evals` skill to turn one AI app behavior into a repeatable eval suite. When the app does not already have a working Promptfoo target, `$promptfoo-provider-setup` helps connect the suite to the application path you want to test.

80Codex can inspect the app, propose high-signal cases, add the Promptfoo config and test data, run the suite locally, and give you a command to keep using.

82This use case works best when the behavior is concrete: support answer quality, retrieval grounding, classifier labels, tool calls, JSON shape, business rules, or prompt and model migration confidence.

84A strong first pass should be reviewable code and test data: a `promptfooconfig.yaml` or equivalent config, a small `evals/` directory, test cases, any target adapter needed to call the app, and a local command such as `npm run evals`.

86## Choose what to evaluate

88Start with one user-visible promise. Avoid asking Codex to evaluate the entire AI system in one pass. A smaller suite is easier to trust, review, and keep running.

90Good first targets include:

92- **Correctness:** classification, extraction, summarization, routing, or transformation.

93- **Grounding:** answers that should stay tied to retrieved documents or cited sources.

94- **Tool use:** choosing the right tool, passing valid arguments, and handling tool errors.

95- **Format or business rules:** JSON schemas, field names, business-rule limits, or UI-facing copy contracts.

96- **Prompt or model migration:** making sure a new prompt, model, system message, or retrieval setting does not break important cases.

98Start from product requirements, bug reports, support escalations, or sanitized examples your team is comfortable committing to the repo.

100## Ask for an eval plan

101

102Codex should inspect before it edits. Ask for a plan that names the target path, fixtures, assertions, adapter, and commands. This gives you a chance to catch the wrong target or weak test cases before files are added.

103

104Review the plan before implementation. It should name the app path or endpoint Promptfoo will call, the first seed cases, the assertions, the files Codex will create, the local command, and any required secrets or services. If the plan tests the raw model instead of the application path users hit, ask Codex whether that is intentional.

105

106## Implement, run, and iterate

107

108Once the plan is correct, ask Codex to implement it. The first implementation should be boring: config, cases, fixtures, a target adapter if needed, a command, and proof that the command ran.

109

110A small app-backed suite might look like this:

111

112```text

113evals/

114 promptfooconfig.yaml

115 tests/

116 cases.yaml

117 providers/

118 provider.js # only if the built-in provider cannot call the app directly

119```

120

121Run the suite before changing behavior. The baseline tells you whether the app already fails the cases, whether the assertions need tuning, or whether the target adapter is wrong. Tune assertions when they are too brittle or vague, but keep real product failures visible.

122

123After the first run, use the suite to compare app changes before they ship. Add new cases whenever a bug, launch requirement, or product review shows behavior you want to keep stable. Once the local command is stable, ask Codex to add it to CI or your release checklist.

102

103## How to use

104

105Ask Codex to check the places where bugs already appear: Sentry alerts, Linear issues, GitHub issues, PR checks, deploy logs, support tickets, and Slack threads. Start with one manual sweep, tune the report in-thread, then run it on a schedule.

106

107Use one Codex thread for the whole triage loop:

108

109

110

1111. Run an on-demand sweep and get a draft list.

1122. Review the list and give feedback in that same thread.

1133. Turn that same thread into an automation.

1144. Optional: ask Codex to draft Linear issues, Slack updates, GitHub comments, or handoff notes when you are confident in the report.

115

116

117

118Before you start, install the [plugins](https://developers.openai.com/codex/plugins) Codex needs, such as Sentry, Slack, Linear, or GitHub. In the starter prompt, replace the bracketed plugin list with real `@` plugin chips. Then replace each bracketed source with the exact place to search: a Sentry project or alert URL, Slack channel or thread, Linear team, view, or query, GitHub repo, issue query, or PR check, deploy link, log file, support queue, or dashboard.

119

120## Phase 1: Run the sweep

121

122Start Codex from the repo that owns the bugs when local context helps: tests, repo tooling, build checks, or CI failures. You can also run the sweep from any repo if your bug sources are available through plugins, connectors, MCP servers, links, exports, pasted logs, or attachments.

123

124Run the starter prompt above first. Keep only the plugins and sources that are part of your sweep.

125

126For example, a filled-in prompt can name the plugins and the exact queues, channels, or repos you want in the sweep.

127

128<div class="not-prose mb-12 rounded-xl bg-[url('/images/codex/codex-wallpaper-1.webp')] bg-cover bg-center p-4 md:p-8">

129 </div>

130

131## Phase 2: Make the report useful

132

133Before you automate, make sure the report is useful enough to read every day.

134

135A useful first run has:

136

137- High-signal bugs sorted from P0 to P3.

138- Duplicate reports are grouped under one bug.

139- Each bug has linked evidence or short citations.

140- Guesses are separated from observed facts.

141- Each bug has a short recommended next action.

142

143Tune the report in the same thread before you automate it. You can ask Codex to:

144

145- Check one more source before ranking the list.

146- Drop noisy alerts that the team already knows about.

147- Only return P0 and P1 bugs.

148- Merge Slack reports, Sentry alerts, and GitHub failures when they point to the same bug.

149- Show the single best link for each bug.

150- Add enough evidence that someone else can reproduce or route the issue.

151

152## Phase 3: Automate it

153

154When the on-demand report is useful, stay in the same thread and turn it into an automation. Codex can use what you refined in the thread to write the recurring automation prompt.

155

156**Create the automation**

157

158## Phase 4: Route follow-ups

159

160Once the scheduled report is useful, decide where the work should go next. Codex can draft a Slack update for a team channel, write Linear issues for the bugs you want to track, write GitHub comments for a failing PR, or produce a handoff for whoever is on call.

~~5Backend stack~~47## Introduction

6 48

~~7Default options~~49Building a game is one of the clearest examples of where Codex helps with more than code generation. A real game usually needs a written concept, a rendering layer, frontend shell work, backend state, asset production, and constant visual tuning

8 50

~~9[Fastify](https://fastify.dev/) , WebSockets, [Postgres](https://www.postgresql.org/) , and [Redis](https://redis.io/)~~51This use case works best when Codex starts by writing down exactly what the game should do, then iterates using Playwright interactive to test the game in a live browser.

10 52

~~11Why it's needed~~53## Start with the game plan

12 54

~~13A strong default when the game needs persistence, matchmaking, leaderboards, or pub/sub.~~55Before Codex scaffolds anything, ask it to create a `PLAN.md` that defines the game in concrete terms:

57- the player goal

58- the main loop

59- inputs and controls

60- win and fail states

61- progression or difficulty

62- visual direction

63- the stack and hosting assumptions

64- the milestone order

66That plan matters because “build a game” is too vague on its own. Codex needs to know how to implement each part of the game, and often refer to the implementation details as it builds.

68You can activate plan mode with the `/plan` slash command.

69Take the output and save it to a `PLAN.md` file.

71## Guide Codex's behavior with AGENTS.md

73To make sure Codex follows the plan, verifies its work and uses the right tools, define an `AGENTS.md` that looks like this:

75```text

76# Game name

78<Type of game>

80Tech Stack:

82- NextJS for frontend (hosted on Vercel)

83- <insert technology> for rendering

84- Fastify for backend, websockets (hosted on <hosting platform>)

85- Postgres for database (hosted on <hosting platform>)

86- Redis for caching and pub/sub (hosted on <hosting platform>)

87- OpenAI for generative AI features

89Tips:

91- Use build and test commands to verify your work as soon as you complete a feature or task

92- Use the PLAN.md file to guide your work when building new features

93- Log your work under .logs (create new log files as you see fit) to record your thought process and decisions, and reference them when iterating on features

94- Use playwright to test the visual output of your work, and iterate if it doesn't look right or fit the vibe

95- Use imagegen to generate visual assets for your work, and every time you generate a collection of assets, save the prompts you used to be able to continue generating more of the same assets later (create files in .prompts)

96- Use Context7 MCP to fetch <rendering framework> docs

97```

99This allows Codex to run independently for a long time, and use the relevant skills as needed.

100

101## Leverage skills

102

103Add the skills mentioned in the AGENTS.md file:

104

105- Imagegen so Codex can generate visual assets for the game as needed

106- Playwright interactive so Codex can test the game in a live browser

107- OpenAI docs so Codex can fetch the latest OpenAI API documentation

108- Optionally, you can add the Context7 MCP server to fetch the latest docs for the rendering framework

109

110Learn more about how to add skills in the [skills documentation](https://developers.openai.com/codex/skills).

111

112**Tip**: Ask Codex to save prompts for image generation in a file so that

113 visual assets are all consistent. Give directions on the style of assets you

114 want to generate, and let Codex come up with detailed reusable prompts.

115

116## Let Codex work and iterate

117

118Codex will generate a first version of the game based on the initial plan.

119

120If you have a lot of image assets that need to be generated, this first version can take a while, sometimes several hours. Since Codex can test its work and try the game in a live browser, it can go on for a long time without any input.

121

122The more defined the plan, the better the final output after the first iteration.

123

124As you test it out, iterate as needed by providing screenshots, asking for gameplay changes or updates to visual assets, until you are happy with the result.

39## Introduction

41If you're working on a budget and want to review the variances or inspect any issues, Codex can help you create a fully functional review workbook you can work with.

43Attach the budget plan, actuals export, and close notes, then ask Codex for an editable review workbook. Codex can preserve the raw inputs, map actuals to plan, calculate variances, and create a summary view you can inspect in the thread.

45## Create the review workbook

491. Attach the budget plan, actuals export, and close notes, or provide exact file references along with the source.

502. Run the starter prompt and ask for an editable `.xlsx` workbook.

513. Open the workbook in Codex. Expand it into the full-screen view to inspect the raw inputs, mappings, variance formulas, and summary tab.

524. Continue in the same thread to fix category mappings, add department cuts, or draft the finance summary.

56If the source files are in a connected app, mention the exact files or folder. Avoid asking Codex to search a broad Drive or workspace when the review should use specific finance sources. When the workbook appears in the thread, open it in Codex and expand it full-screen to review the raw inputs, mappings, variance formulas, and summary tab before asking for revisions.

58## Check the variances

60Before sharing the workbook, ask Codex to audit the categories, formulas, and variance explanations.

39## Introduction

41When you are building a cash-flow forecast, you want to make sure it is accurate and reflects the reality of your business. You can use Codex to help you create a forecast workbook that you can inspect and revise in Codex. Attach the cash-flow inputs, operating assumptions, and model constraints. You can also use file references when the inputs live in Google Drive or another connected source.

43## Make the forecast

471. Attach the cash-flow inputs, operating assumptions, and model constraints.

482. Run the starter prompt and ask for an editable `.xlsx` workbook.

493. Open the workbook in Codex. Expand it into the full-screen view to inspect assumptions, formulas, scenarios, and the summary tab.

504. Continue in the same thread to change collections, payroll, vendor payment, growth, or safety-balance assumptions.

54When the workbook appears in the thread, open it in Codex and expand it full-screen. Review the timing assumptions, formulas, scenarios, and summary tab, then ask Codex to revise the same workbook from there.

56## Review cash pressure

58Before using the forecast, ask Codex to identify the low point, tie the workbook back to the source inputs, and list assumptions that need review.

60## Run a scenario

62After reviewing the workbook in Codex, use follow-up prompts to change one scenario driver at a time.

74## What you build

76Every ChatGPT app has three parts:

78- An MCP server that defines tools, returns data, enforces auth, and points ChatGPT at any UI resources.

79- An optional web component that renders inside a ChatGPT iframe. You can build it with React or with plain HTML, CSS, and JavaScript.

80- A model that decides when to call the app's tools based on the metadata you provide.

82Codex is most useful when it owns the repetitive engineering work around those parts:

84- Planning the tool surface and metadata.

85- Scaffolding the server and widget.

86- Wiring local run scripts.

87- Adding auth and deployment changes in focused passes.

88- Writing the verification loop that proves the app works in ChatGPT.

90## Why Codex is a strong fit

92- ChatGPT apps already split cleanly into a server, an optional widget, and model-driven tool calls.

93- Codex prompting works best when the task is explicit, scoped, and straightforward to verify, which matches app-building work well.

94- Skills and `AGENTS.md` give Codex the reusable instructions and project rules it needs to stay grounded.

96To learn more about how to install and use skills, see our [skills documentation](https://developers.openai.com/codex/skills).

98## How to use

100## Prerequisites

101

102- Start with one core user outcome instead of trying to port an entire product into chat.

103- Choose the stack up front: TypeScript or Python for the server, and React or plain HTML, CSS, and JavaScript for the widget.

104- Decide what HTTPS path you will use during development, such as `ngrok` or Cloudflare Tunnel.

105- Current docs usually say app, but some older pages and settings still say connector. During local testing, treat them as the same setup object.

106

1071. Start with one narrow app outcome and ask Codex to propose three to five tools with clear names, descriptions, inputs, and outputs.

1082. Decide whether v1 can stay data-only or needs a widget, then scaffold the MCP server and optional widget using existing repo patterns before adding dependencies.

1093. Run the app locally behind HTTPS, connect it in ChatGPT developer mode, and test it with a small direct, indirect, and negative prompt set.

1104. Iterate on metadata, state handling, `structuredContent`, and `_meta` payloads until the core read flow behaves reliably inside ChatGPT.

1115. Add OAuth 2.1 only when user-specific data or write actions require it, while keeping anonymous or read-only flows simple where possible.

1126. Prepare a hosted preview with a stable `/mcp` endpoint, verify streaming and widget asset hosting, and review the launch checklist before sharing or submitting the app.

113

114## Suggested prompts

115

116Strong prompts for this workflow share the same ingredients:

117

118- One clear outcome: say what the app should help the user do inside ChatGPT.

119- A concrete stack: say whether you want TypeScript or Python on the server, and whether the widget should use React or stay lightweight.

120- Explicit tool boundaries: ask Codex to propose or build a small set of tools with one job per tool.

121- Auth expectations: state whether the first version can be anonymous or whether it needs linked accounts and write actions.

122- A local development path: mention the tunnel or hosting path you expect for HTTPS testing in ChatGPT.

123- Verification steps: tell Codex what commands to run, what prompts to test, and what evidence to report back.

124

125Avoid one giant prompt that asks for planning, implementation, auth, deployment, submission, and polish in one pass. Split the work into smaller milestones instead.

126

127**Plan the App Before You Scaffold It**

128

129**Scaffold the First Working Version**

130

131**Add Auth Only After the Core Flow Works**

132

133**Prepare the App for Deployment and Review**

134

135## Launch readiness

136

137- The app has one narrow outcome that is obvious to a user.

138- The tool set stays small and has explicit metadata, inputs, and outputs.

139- The MCP server works end to end and returns concise `structuredContent`, reserving widget-only data for `_meta`.

140- The widget, if needed, renders correctly inside ChatGPT.

141- A local HTTPS testing loop works through ChatGPT developer mode.

142- A small direct, indirect, and negative prompt set passes with the expected conversation flow and tool payloads.

143- Auth is added only where user-specific data or write actions require it.

144- A deployment plan and launch-readiness review cover metadata, tool hints, privacy, and test prompts before the app is shared or submitted.

145

146## Common pitfalls

147

148- Asking Codex to port the whole product into ChatGPT. Better move: ask for one core user outcome, three to five tools, and one narrow widget.

149- Starting with a giant implementation prompt. Better move: split the work into planning, scaffold, auth, deployment, and review passes.

150- Writing UI before the tool contract is clear. Better move: plan the tool surface and response schema first, then build the widget.

151- Skipping official docs grounding. Better move: pair `$chatgpt-apps` with `$openai-docs` so the scaffold follows current Apps SDK guidance.

152- Treating metadata as an afterthought. Better move: write tool descriptions and parameter docs early, then replay a prompt set against them.

153- Adding auth before proving the anonymous or read-only path. Better move: get the core tool flow working first, then add OAuth for the tools that actually need it.

154- Declaring the app done before testing inside ChatGPT. Better move: connect the app in developer mode, inspect tool payloads, and verify the real conversation flow.

57## Introduction

59Codex is great at cleaning systematically tabular data.

60When a CSV or spreadsheet has mixed dates, duplicate rows, currency strings, blank cells, aliases, or pasted summary rows, ask Codex to clean a copy and leave the original file unchanged.

62## How to use

661. Drag the file into Codex or mention it in your prompt, such as `@customer-export.csv`.

672. Describe the problems you already see.

683. Tell Codex what the cleaned version should be: CSV, spreadsheet tab, or upload-ready file.

694. Review the cleaned copy before using it.

73Use the starter prompt on this page for the first cleaning pass. Replace the file name and bullets with your own. The useful details are the problems you already see and the file you need next: a cleaned CSV, a clean spreadsheet tab, or an upload-ready file. After Codex writes the clean copy, open the cleaned file and the data-quality note from the thread before using the data downstream.

64## Introduction

66When you are moving from one stack to another, you can leverage Codex to map and execute a controlled migration: routing, data models, configuration, auth, background jobs, build tooling, deployment, tests, or even the language and framework conventions themselves.

68Codex is useful here because it can inventory the legacy system, map old concepts to new ones, and land the change in checkpoints instead of one giant rewrite. That matters when you are moving off a legacy framework, porting to a new runtime, or incrementally replacing one stack with another while the product still has to keep working.

70## How to use

741. Start by inventorying the migration surface: legacy packages, framework conventions, routing, data access, auth, configuration, build tooling, tests, deployment assumptions, and any external contracts that must survive the move.

752. Ask Codex to map the legacy concepts to the target stack and call out what has no direct match.

763. Choose an incremental strategy: compatibility layer, module-by-module port, branch-by-abstraction, or a strangler-style replacement around one boundary at a time.

774. Keep behavior stable until the migration itself forces a visible change, and name those exceptions explicitly.

785. After each milestone, run the smallest validation that proves parity: lint, type-check, focused tests, contract tests, smoke tests, or a side-by-side check against the legacy path.

796. Review the diff and the remaining transition risk after each checkpoint instead of waiting for the full rewrite.

83## Leverage ExecPlans

85In our [code modernization cookbook](https://developers.openai.com/cookbook/examples/codex/code_modernization), we introduce ExecPlans: documents that let Codex keep an overview of the cleanup, spell out the intended end state, and log validation after each pass.

86When you ask Codex to run a complex migration, ask it to create an ExecPlan for each part of the system to make sure every decision and tech stack choice is recorded and can be reviewed later.

88## Combine with a goal

90For long-running migration slices, use a [goal](https://developers.openai.com/codex/use-cases/follow-goals) to guide Codex through the work. Set the goal with a clear end state, parity checks, rollback expectations, and a stopping condition.

33## Introduction

35Many message threads contain hidden to-dos: book dinner, schedule a follow-up, research options, submit a receipt, or pull together information for a reply. Computer Use can help by reading the thread, identifying the task, and completing the work across the apps involved.

37This is a good fit when the message contains a concrete request and you want Codex to handle the follow-through, not just summarize the thread.

39## How to use

411. Install the [Computer Use plugin](https://developers.openai.com/codex/app/computer-use).

422. Ask Codex to review a specific message thread or sender.

433. Tell it what action to take and whether it should pause before completing anything.

444. Specify whether it should draft a reply in the original thread.

46For example:

48- `@Computer Look at my messages from [person]. Check my availability, find 2 dinner options in Hayes Valley, and draft a reply in the same thread. Check in with me before completing booking.`

50## Practical tips

52### Ask for a pause before irreversible actions

54If the task might send money, submit an order, confirm a booking, or finalize a schedule, tell Codex to stop and ask before taking that last step.

56### Make sure the supporting apps are ready

58This works best when the related apps are already signed in and available. If the task depends on Maps, Calendar, Notes, a reservation site, or a browser session, prepare those ahead of time.

60### Expect the thread to be marked as read

62When Codex opens the thread in Messages, it will behave like a normal user viewing the conversation. Treat that as a read.

64## Good follow-ups

66This same pattern can work for other inbox-style surfaces too, such as Slack or email, when the work starts from a message and finishes somewhere else. If the workflow becomes common, add a reusable preference or instruction in [customization](https://developers.openai.com/codex/concepts/customization) so Codex handles those requests the same way every time.

90## Introduction

92At its core, data analysis is about using data to inform decisions. The goal isn't analysis for its own sake. It's to produce an artifact that helps someone act: a chart for leadership, an experiment readout for a product team, a model evaluation for researchers, or a dashboard that guides daily operations.

94A useful framework, popularized by _R for Data Science_, is a loop: import and tidy data, then iterate between transform, visualize, and model to build understanding before you communicate results. Programming surrounds that whole cycle.

96Codex fits well into this workflow. It helps you move around the loop faster by cleaning data, exploring hypotheses, generating analyses, and producing reproducible artifacts. The target isn't a one-off notebook. The target is a workflow that other people can review, trust, and rerun.

98## Define your use case

100Choose one concrete question you want to answer with your data.

101

102The more specific the question, the better. It will help Codex understand what you want to achieve and how to help you get there.

103

104### Running example: Property values near the highway

105

106As an example, we'll explore the following question:

107

108> To what extent are houses near the highway lower in property valuation?

109

110Suppose one dataset contains property values or sale prices, and another contains location, parcel, or highway-proximity information. The work isn't only to run a model. It's to make the inputs trustworthy, document the joins, pressure-test the result, and end with an artifact that somebody else can use.

111

112## Set up the environment

113

114When you start a new data analysis project, you need to set up the environment and define the rules of the project.

115

116- **Environment:** Codex should know which Python environment, package manager, folders, and output conventions are canonical for the project.

117- **Skills:** Repeated workflows such as notebook cleanup, spreadsheet exports, or final report packaging should move into reusable skills instead of being re-explained in every prompt.

118- **Worktrees:** Separate explorations into separate worktrees so one hypothesis, merge strategy, or visualization branch doesn't bleed into another.

119

120To learn more about how to install and use skills, see our [skills documentation](https://developers.openai.com/codex/skills).

121

122### Guide Codex's behavior

123

124Before touching the data, tell Codex how to behave in the repo. Put personal defaults in `~/.codex/AGENTS.md`, and put project rules in the repository `AGENTS.md`.

125

126A small `AGENTS.md` is often enough:

127

128```md

129## Data analysis defaults

130

131- Use `uv run` or the project's existing Python environment.

132- Keep source data in `data/raw/` and write cleaned data to `data/processed/`.

133- Put exploratory notebooks in `analysis/` and final artifacts in `output/`.

134- Never overwrite raw files.

135- Prefer scripts or checked-in notebooks over unnamed scratch cells.

136- Before merging datasets, report candidate keys, null rates, and join coverage.

137```

138

139If the repo doesn't already define a Python environment, ask Codex to create a reproducible setup and explain how to run it. For data analysis work, that step matters more than jumping straight into charts.

140

141## Import the data

142

143Often the fastest way to start is to paste the file path and ask Codex to inspect it. This is where Codex helps you answer basic but important questions:

144

145- What file formats are here?

146- What does each dataset seem to represent?

147- Which columns might be targets, identifiers, dates, locations, or measures?

148- Where are the clear quality issues?

149

150Don't ask for conclusions yet. Ask for inventory and explanation first.

151

152## Tidy and merge the inputs

153

154Most real work starts here. You have two or more datasets, the primary key isn't clear, and a naive merge could lose data or create duplicates.

155

156Ask Codex to profile the merge before performing it:

157

158- Check uniqueness for candidate keys.

159- Measure null rates and formatting differences.

160- Normalize clear formatting issues such as casing, whitespace, or address formatting.

161- Run trial joins and report match rates.

162- Recommend the safest merge strategy before it writes the final merged file.

163

164If you need to derive the best key, such as a normalized address, a parcel identifier built from a few columns, or a location join, make Codex explain the tradeoffs and edge cases before you accept the merge.

165

166## Explore with charts and separate worktrees

167

168Exploratory data analysis is where Codex benefits from clean isolation. One worktree can test address cleanup or feature engineering while another focuses on charts or alternate model directions. That keeps each diff reviewable and prevents one long thread from mixing incompatible ideas.

169

170The Codex app includes built-in worktree support. If you are working in a terminal, plain Git worktrees work well too:

171

172```bash

173git worktree add ../analysis-highway-eda -b analysis/highway-eda

174git worktree add ../analysis-model-comparison -b analysis/highway-modeling

175```

176

177In the running example, this step is where you would compare homes near the highway against homes farther away, examine outliers, inspect missing-value patterns, and decide whether the observed effect looks real or reflects neighborhood composition, home size, or other factors.

178

179## Model the question

180

181Not every analysis needs a complex model. Start with an interpretable baseline.

182

183For the highway question, a sensible first pass is a regression or other transparent model that estimates the relationship between highway proximity and property value while controlling for relevant factors such as size, age, and location.

184

185Ask Codex to be explicit about:

186

187- The target variable and feature definitions.

188- Which controls to include and why.

189- Leakage risks and exclusions.

190- How it chose the split, evaluation, or uncertainty estimate.

191- What the result means in plain language.

192

193If the first model is weak, that's still useful. It tells you whether the problem is the model, the features, the join quality, or the question itself.

194

195## Communicate the result

196

197The analysis is only useful when someone else can consume it. Ask Codex to produce the artifact the audience needs:

198

199- A Markdown memo for technical collaborators.

200- A spreadsheet or CSV for downstream operations work.

201- A `.docx` brief using `$doc` when formatting and tables matter.

202- A rendered appendix or final deliverable using `$pdf`.

203- A lightweight dashboard or static report site deployed with `$vercel-deploy`.

204

205This is also where you ask for caveats. If the join quality is imperfect, sampling bias is present, or the model assumptions are fragile, Codex should say that plainly in the deliverable.

206

207## Skills to consider

208

209The curated skills that fit this workflow especially well are:

210

211- `$spreadsheet` for CSV, TSV, and Excel editing or exports.

212- `$jupyter-notebook` when the deliverable should stay notebook-native.

213- `$doc` and `$pdf` for stakeholder-facing outputs.

214- `$vercel-deploy` when you want to share the result as a URL.

215

216Once the workflow stabilizes, create repo-local skills for the repeated parts, such as `refresh-data`, `merge-and-qa`, or `publish-weekly-report`. That's a better long-term pattern than pasting the same procedural prompt into every thread.

44## Introduction

46Codex can help you create a fully functional DCF workbook that you can inspect and revise.

48It can use multiple files as context, including the historical financials, valuation assumptions, and any modeling notes.

49You can provide these files directly, or use file references when the inputs live in Google Drive or another connected source. If so, provide the exact file references, as it will be more effective than asking Codex to search through all of your files.

51## Create the workbook

551. Attach the historical financials, valuation assumptions, and any modeling notes, or provide exact file references along with the source.

562. Run the starter prompt and ask for an editable `.xlsx` workbook.

573. Open the generated workbook in Codex. Expand it into the full-screen view to inspect the model tabs, formulas, assumptions, and valuation summary.

584. Continue in the same thread to check formula links, change assumptions, add scenarios, or tighten the model.

62When the workbook appears in the thread, open it in Codex and expand it full-screen. Review the source inputs, forecast drivers, valuation outputs, and sensitivity tables, then ask Codex to revise the same workbook from there.

64## Check the valuation

66Before using the workbook, ask Codex to review the model like a finance teammate would: source tie-outs, formulas, hardcoded assumptions, and valuation outputs.

68## Revise one assumption

70After reviewing the workbook in Codex, ask for targeted revisions in the same thread. Change one driver at a time so the impact is easy to inspect.

53## Start with the site and the deploy target

55Codex can build or update a website or app, run the project checks, deploy it with Vercel, and return the URL.

57The useful handoff is concrete: a repo, screenshot, map, design brief, product note, API doc, or data source. Codex should inspect the project before changing it, then use the Vercel plugin to deploy a preview by default.

59Use `@build-web-apps` when Codex needs to build or polish the app. Use `@vercel` when it should deploy, inspect the deployment, or read Vercel build logs.

61## Check the result before you share it

63Codex should tell you what it changed, which command it used to build the project, and whether the Vercel deployment is ready. If the deploy needs an environment variable, team choice, domain setting, or login step, Codex should call that out instead of pretending the site is finished.

65Keep production changes explicit. A preview deployment is the default; ask for production only when you mean it.

67## Iterate from the live URL

69Once you have the preview, keep the same thread open. Ask Codex to open the URL, fix layout issues, update copy, wire missing data, or read Vercel logs if the deploy fails. The thread already has the repo, deployment, and build context.

71Good follow-ups are specific:

73- "The mobile layout is cramped. Fix it and redeploy the preview."

74- "Use the same project and add the latest data from [source]."

75- "Read the failed build logs and fix the deploy."

59## Introduction

61Before working on a new product or feature, it's common to draft a product requirements document (PRD) to align on the scope and requirements. Most often than not, the context needed to write that PRD is already available in the team's internal systems: tickets on Linear, discussions on Slack, drafts in Notion or Google Drive, etc. Codex can gather this context and draft a PRD that you can review and iterate on, while keeping the source trail visible.

63## Choose the sources

65Start with the sources you want Codex to use: the Linear project, the Slack planning channel or thread, and any Drive docs, Notion pages, meeting notes, or local files that should be cited in the PRD.

66You should also clearly outline the PRD sections you expect, such as the problem, users, requirements, UX, tech, launch plan, timeline, or decisions.

701. Start with `$documents` when the output should be a real DOCX.

712. Name the sources directly: the Linear project or milestone, the Slack channel or thread, and the docs or notes Codex should cite.

723. Give Codex the PRD section contract.

734. Review the source appendix first, then the requirements and open questions.

745. Use the same thread to resolve gaps, tighten scope, and prepare the handoff.

78## Refine in the same thread

80Use the starter prompt on this page for the first draft. If something is missing, point Codex at the missing source instead of starting over.

82## Check the source trail

84Before sharing the PRD, ask Codex to list the claims with weak or missing support, the unresolved questions, and the decisions it treated as confirmed. If the source appendix does not make those easy to audit, keep refining the same thread before exporting or posting anything.

69---

71## Introduction

73When you have an exact Figma selection, Codex can turn it into polished UI without ignoring the patterns already established in your project.

75With the Figma skill, Codex can use the Figma MCP server to pull structured design context, variables, assets, and the exact variant it should implement.

77With the Playwright interactive skill, Codex can open the app in a real browser, compare the implementation to the Figma reference, and iterate on layout or behavior until the result is closer to the target.

79## Set up your Figma project

81The cleaner your Figma file is, the better the first implementation will be. To improve the handoff:

83- Use variables or design tokens wherever possible, especially for colors, typography, and spacing

84- Create components for reusable UI elements instead of repeating detached layers

85- Use auto layout as much as possible instead of manual positioning

86- Keep frame and layer names clear enough that the main screen, state, and variants are obvious

87- Keep real icons and images in the file when possible so Codex does not need to guess

89This gives Codex better structure to translate into a robust, production-ready UI.

91## Be specific

93The more specific you are about the expected interaction patterns and the style you want, the better the result will be.

95If a state, breakpoint, or interaction matters, call it out. If the file contains multiple close variants, tell Codex which one should be treated as the source of truth.

97The more explicit you are about what needs to match exactly and where repo conventions should win, the easier it is for Codex to make the right tradeoffs.

99## Prepare the design system

100

101Codex works best when the target repo already has a clear component layer. Codex can automatically use your existing component and design system instead of recreating them from scratch.

102

103If you think it's necessary, specify to Codex which primitives to reuse, where your tokens live, and what the repo considers canonical for buttons, inputs, cards, typography, and icons.

104

105Treat the Figma MCP output, which often looks like React plus Tailwind, as a structural reference rather than final code style. Ask Codex to translate that output into the project's actual utilities, component wrappers, color system, typography scale, spacing tokens, routing, state management, and data-fetch patterns.

106

107## Workflow

108

109### Start from a Figma selection

110

111Copy a link to the exact Figma frame, component, or variant you want implemented. The Figma MCP flow is link-based, so the link needs to point to the exact node you want rather than a nearby parent frame.

112

113### Prompt Codex to use Figma

114

115Figma should drive the first pass. Ask Codex to follow the Figma MCP flow before it starts implementing.

116

117Things to include in your prompt:

118

119Once the first implementation is in place, Codex will use Playwright to verify the UI in a real browser and tighten any remaining visual or interaction mismatches.

23---

25## Introduction

27Use `/goal` when you want Codex to keep working toward one durable objective instead of stopping after one normal turn. It is useful for work that has a clear target, a validation loop, and enough room for Codex to make progress without asking you to steer every step. When you use `/goal`, Codex can work independently for multiple hours without needing your input.

29`/goal` is an experimental Codex CLI feature. Enable it from `/experimental`, or add `goals = true` under `[features]` in `config.toml`. Then set a goal with `/goal <objective>`, check the current goal with `/goal`, and use `/goal pause`, `/goal resume`, or `/goal clear` when you need to control the run.

31## Choose the right work

33A good goal is bigger than one prompt but smaller than an open-ended backlog. It should define what Codex should achieve, what it should not change, how it should validate progress, and when it should stop.

35This works well for:

37- code migration where the target stack, parity checks, and constraints are clear

38- large refactors where Codex can run tests after each checkpoint

39- experiments, games, or prototypes where Codex can keep improving a working artifact

41Avoid using a goal for a loose list of unrelated work.

43## Set up the loop

471. Name one objective and one stopping condition.

482. Point Codex at the files, docs, issue, logs, or plan it must read first.

493. Define the commands or artifacts that prove progress.

504. Tell Codex to work in checkpoints and keep a short progress log.

515. Use `/goal` to inspect status while it runs.

526. Pause, resume, or clear the goal when the run is done, blocked, or changing direction.

56The important part is the contract. Codex should know what "done" means before it starts. If the goal is a migration, "done" might mean the new path passes contract tests and the legacy path still has a rollback. If the goal is a game or prototype, "done" might mean the app builds, launches, and matches the input reference or expected behavior.

58Ask Codex to help: start by having a conversation about what you want to

59 build, then ask it to directly set a goal and start working.

61## Let Codex work independently

63During a goal, ask for compact progress reports that make the run easy to trust. A useful status update names the current checkpoint, what was verified, what remains, and whether Codex is blocked.

64If the status becomes vague, tighten the goal rather than adding more ad hoc instructions. Tell Codex exactly which checkpoint matters next, which command proves it, and what should cause it to pause.

66When Codex follows a goal, it can work independently for many hours without you having to check in. It will stop running when it is fairly confident it has reached the stopping condition, so you should think of `/goal` as a background task you don't need to monitor.

68## Example goals

70### Migrations

72Whether you're migrating games to a new stack, mobile apps to a new platform, or a codebase to a new framework, you can use `/goal` to have Codex run the migration:

74### Prototype creation

76Whether you're creating a new app from scratch, a new game, or a new feature, you can use `/goal` to have Codex complete a polished first version. You can use a PLAN.md file to guide the creation of the first version, describing precisely what you want to build.

78### Prompt optimization

80When you have an eval suite, you can use `/goal` to optimize prompts against the eval results. Codex can inspect failures, update the prompt, rerun the evals, and keep iterating until the score improves or it reaches your stopping condition.

48## Start with a visual direction

50GPT Image 2 is great at generating high quality UI mockups. Instead of starting from scratch when exploring new ideas, you can leverage image generation to get a visual direction.

52You can do this in two ways:

54- Iterate on the visual direction using the ImageGen skill, and once you are satisfied with the proposed UI, you can ask Codex to build a prototype matching the visuals. In that case, make sure to copy the final image you want to implement in a new turn rather than continuing the conversation directly – Codex will do better when it can reference a user attachment.

55- Use a plugin and simply describe your idea: the plugin will generate the visual direction for you and handle next steps.

57## Leverage a plugin

59If you do not need to iterate on the visual direction before starting the implementation, you can use a plugin and describe your idea.

61Use the [Build Web Apps plugin](https://github.com/openai/plugins/tree/main/plugins/build-web-apps)

62for web apps, dashboards, creative websites, and frontend-heavy tools. Its

63workflow pushes Codex to generate a design first, match it in code, and use the

64browser to compare the result back to the concept.

66Use the [Game Studio plugin](https://github.com/openai/plugins/tree/main/plugins/game-studio)

67when the proof of concept is a browser game. That path should define the player

68verbs, first playable loop, engine, asset workflow, HUD, controls, and browser

69test before expanding the game.

71## Iteration workflow

73A good proof of concept is scoped to an MVP that can be implemented quickly and validated with the team.

74If you want to make sure the MVP is working as expected, you can use Playwright interactive to let Codex verify its work.

76Once you have a first version working, you can iterate on it by asking for scoped changes in the same conversation:

92---

94## Make the right parts of your app visible to the system

96App Intents are one of the clearest ways to make an iOS app more useful outside its own UI. Instead of treating your app as a sealed destination that only works after someone launches it and taps around, use Codex to expose the actions and objects that should be available to Shortcuts, Siri, Spotlight, widgets, controls, and newer assistant-driven system experiences.

98That is useful today for discoverability and automation, and it is a strong preparation step for a more assistant-driven future. If your app already knows how to compose, open, filter, route, or summarize something valuable, App Intents give the system a structured way to ask for that capability.

100## Start with actions and entities, not with every screen

101

102The best first App Intents pass is usually not “mirror the whole app.” Ask Codex to identify:

103

104- the few actions a user would want to trigger without navigating the full interface

105- the app objects the system needs to understand to route those actions correctly

106- the workflows that should open the app in a specific state versus the ones that should complete directly from a system surface

107

108Apple’s App Intents guidance is a good frame here: define the action, define the entity surface the system needs, then make those actions discoverable and reusable across system experiences. The most useful references are [Making actions and content discoverable and widely available](https://developer.apple.com/documentation/appintents/making-actions-and-content-discoverable-and-widely-available), [Creating your first app intent](https://developer.apple.com/documentation/appintents/creating-your-first-app-intent), and the system-experience sample [Adopting App Intents to support system experiences](https://developer.apple.com/documentation/appintents/adopting-app-intents-to-support-system-experiences).

109

110## Think in system surfaces, not just in shortcuts

111

112The opportunity is broader than “add one shortcut.” A good App Intents surface can make your app useful in several places:

113

114- Shortcuts, where users can run actions directly or compose them into larger automations

115- Siri, where the app can expose meaningful verbs and deep links instead of only opening generically

116- Spotlight, where app entities and app shortcuts become discoverable system entry points

117- widgets, Live Activities, controls, and other intent-driven UI surfaces

118- newer assistant-facing experiences, where structured actions and entities are much easier for the system to understand than arbitrary UI flows

119

120## Follow a real app pattern

121

122This usually works best when the app adopts a structure like this:

123

124- a dedicated App Intents target instead of scattering intent types across unrelated app files

125- `AppShortcutsProvider` entries for high-value user actions like composing a post or opening the app on a specific tab

126- small `AppEntity` types for things the system needs to reason about, such as accounts, lists, and timeline filters

127- intent handling that routes back into the main app scene cleanly, so an invoked intent can open the right compose flow or switch the app to the right tab

128

129That is the pattern I would ask Codex to follow for most apps: start with a small system-facing action layer, keep the entity surface narrow, and wire a predictable runtime handoff back into the app when the intent needs the main UI.

130

131## Ask Codex to design the first intent surface

132

133The strongest prompt here is one that gives Codex your app’s core objects and top user actions, then asks it to choose the smallest useful first App Intents surface instead of blindly exposing everything.

134

135## Practical tips

136

137### Expose verbs users actually want outside the app

138

139Good first intents are usually things like compose, open, find, filter, start, continue, or inspect. If an action is only useful after a long in-app setup flow, it may not belong in the first App Intents pass.

140

141### Keep entities smaller than your model layer

142

143The system usually does not need your full persistence model. Ask Codex to define the smallest app entity surface that still gives Siri, Shortcuts, and Spotlight enough context to route and display the action correctly.

144

145### Treat this as assistant infrastructure, not only a shortcuts feature

146

147Even if your first release only visibly improves Shortcuts or Siri, the deeper win is that your app starts speaking in structured actions and entities. That makes it easier to participate in future system and AI-driven entry points than an app whose capabilities are only encoded in taps and view hierarchies.

10 37

~~11Why it's needed~~38 - Prefer system controls and native APIs like `glassEffect`,

39 `GlassEffectContainer`, `glassEffectID`, `.buttonStyle(.glass)`, and

40 `.buttonStyle(.glassProminent)` over custom blurs. Use `glassEffectID` with

78 why: Build, launch, screenshot, and log inspection matter during a visual

80---

82## Start from the iOS 26 baseline

84Treat Liquid Glass as an iOS 26 and Xcode 26 migration project first. Rebuild the app with the iOS 26 SDK, inspect what you get automatically from standard SwiftUI controls, and only then ask Codex to redesign the custom parts that still look too flat, too heavy, or too detached from system chrome.

86If the app still supports earlier iOS versions, make that constraint explicit up front. The SwiftUI Liquid Glass skill in the [Build iOS Apps plugin](https://github.com/openai/plugins/tree/main/plugins/build-ios-apps) should gate new glass-only APIs with `#available(iOS 26, *)` and keep a fallback path that still reads well on older devices.

88## Leverage the iOS plugin

90Use the [Build iOS Apps plugin](https://github.com/openai/plugins/tree/main/plugins/build-ios-apps) when you want Codex to combine SwiftUI UI changes with simulator-backed verification. For Liquid Glass work, the useful move is to ask Codex to audit one flow, migrate a small set of surfaces, launch the result on an iOS 26 simulator, and capture screenshots before expanding the scope.

92That plugin includes a SwiftUI Liquid Glass skill with a simple set of defaults worth carrying into your prompt:

94- Prefer native `glassEffect`, `GlassEffectContainer`, glass button styles, and `glassEffectID` transitions over custom blur views.

95- Apply `.glassEffect(...)` after layout and visual modifiers so the material wraps the final shape you actually want.

96- Wrap related glass elements in `GlassEffectContainer` when multiple surfaces appear together.

97- Use `.interactive()` only on buttons, chips, and controls that actually respond to touch.

98- Keep corner shapes, tinting, and spacing consistent across the feature instead of mixing one-off glass treatments.

99- Preserve a non-glass fallback for pre-iOS 26 targets.

103## Watch the WWDC sessions

104

105These WWDC25 sessions are a good reference set before you ask Codex to refactor a real production flow:

106

107- [Meet Liquid Glass](https://developer.apple.com/videos/play/wwdc2025/219/)

108- [Get to know the new design system](https://developer.apple.com/videos/play/wwdc2025/356/)

109- [Build a SwiftUI app with the new design](https://developer.apple.com/videos/play/wwdc2025/323/)

110- [Build a UIKit app with the new design](https://developer.apple.com/videos/play/wwdc2025/284/)

111- [What's new in SwiftUI](https://developer.apple.com/videos/play/wwdc2025/256/)

112

113## Prompt a migration plan, then a slice

114

115Liquid Glass migrations go better when Codex separates "where should glass appear?" from "write all the code now." Ask for a quick audit first, then let the agent implement one self-contained slice with simulator verification.

116

117## Practical tips

118

119### Do not glass everything

120

121Liquid Glass should create a clear control layer above content, not turn every card into a glowing panel. Ask Codex to remove decorative backgrounds that fight system materials, preserve plain content where readability matters most, and reserve tinting for semantic emphasis or primary actions.

122

123### Start with one high-traffic flow

124

125A tab root, detail screen, sheet, search surface, or onboarding flow is usually a better first migration target than a full app-wide sweep. That keeps review easier and makes it clear which Liquid Glass decisions should become reusable component patterns.

126

127### Review fallback behavior deliberately

128

129If your deployment target is below iOS 26, ask Codex to show the fallback implementation alongside the Liquid Glass version. That review step catches accidental API availability regressions and avoids shipping a migration that only works on the latest simulator.

95---

97## Give Codex the whole simulator loop

99This use case works best when Codex owns the full loop: choose the right app target, launch the app in Simulator, inspect the current screen, perform the reproduction steps, gather logs and screenshots, inspect a stack trace if needed, patch the code, and rerun the same path to prove the bug is gone.

100

101Use the [Build iOS Apps plugin](https://github.com/openai/plugins/tree/main/plugins/build-ios-apps) when you want that loop to stay agentic. Its iOS debugger workflow is built around XcodeBuildMCP, which means Codex can interact with a booted simulator and gather the same evidence a human would normally collect by hand.

102

103When XcodeBuildMCP is configured with simulator automation, UI automation, debugging, and logging workflows, Codex can own the full reproduce-debug-verify loop. If Codex has not picked a project, scheme, and simulator yet, ask it to discover those first and reuse that setup for the rest of the session.

104

105## Leverage what XcodeBuildMCP can do

106

107These are the practical capability groups to prompt Codex to use:

108

109- Project and simulator discovery: check whether Codex already knows which app target and simulator to use, discover the Xcode project or workspace, enumerate schemes, find or boot a simulator, and keep that setup stable for future build/run steps.

110- Build and launch control: build the active app target, install and launch the simulator build, relaunch with log capture when needed, and resolve the app bundle id if Codex needs to inspect app-specific runtime logs.

111- UI inspection and interaction: read the on-screen accessibility hierarchy, take screenshots, tap controls, type into fields, scroll through lists, and perform edge swipes or other simulator gestures.

112- Logs and debugger state: stream simulator logs, attach LLDB to the running app, set breakpoints, inspect stack frames and local variables, and run debugger commands when a crash or hang needs deeper inspection.

113

114The key habit is to ask Codex to inspect the view tree before it taps. XcodeBuildMCP exposes the accessibility hierarchy plus coordinates, so Codex can prefer stable labels or element IDs instead of guessing raw screen positions.

115

116## Turn a vague bug into a reproducible script

117

118The iOS debugger skill is most effective when your prompt gives one concrete bug and one expected outcome, then lets Codex drive the app and collect evidence autonomously. If a login, deep link, or test fixture is required, say that once and ask Codex to pause only when that missing input blocks progress.

119

120## Practical tips

121

122### Ask for evidence, not just a fix

123

124Request the exact simulator, scheme, screenshots, log snippets, and stack details that Codex used to explain the bug. That makes the final patch much easier to review than "I think this should fix it."

125

126### Prefer accessibility labels over coordinates

127

128If Codex has to tap by coordinates because a control has no stable label or accessibility identifier, ask it to call that out. That is often a signal that the bug fix should include a small UI testability improvement too.

129

130### Keep one bug per run

131

132A simulator-driven debugging loop is powerful, but it is still easier to trust when one prompt targets one failure mode. Ask Codex to finish one reproduce-fix-verify cycle before expanding to adjacent issues.

95## Refactor one screen without changing what it does

97This use case is for the moment when a SwiftUI file has grown into one giant screen and every small edit feels risky. The goal is not to redesign the feature or invent a new architecture. Ask Codex to preserve behavior and layout, then split the screen into small subviews with explicit data flow so the next change becomes easier to review.

99Use the [Build iOS Apps plugin](https://github.com/openai/plugins/tree/main/plugins/build-ios-apps) for this kind of cleanup. Its SwiftUI view refactor skill is opinionated in a useful way: default to MV over MVVM, keep business logic in services or models, use local view state and environment dependencies first, and only keep a view model when the feature clearly needs one.

100

101## What to ask Codex to do

102

103Start by naming one concrete screen file and asking Codex to preserve behavior while improving structure. These are the refactor rules worth putting directly in your prompt:

104

105- Reorder the file so environment dependencies, stored properties, computed non-view state, `init`, `body`, view helpers, and helper methods are easy to scan top to bottom.

106- Extract meaningful sections into dedicated `View` types with small explicit inputs, `@Binding`s, and callbacks.

107- Keep computed `some View` helpers rare and small. Do not rebuild one giant screen as a long list of private computed view fragments.

108- Move non-trivial button actions and side effects out of `body`, and move real business logic into services or models.

109- Keep the root view tree stable. Prefer localized conditionals in sections or modifiers over top-level `if/else` branches that swap whole screens.

110- Fix Observation ownership as you go. For root `@Observable` models on iOS 17+, the owning view should store them in `@State`; use legacy observable wrappers only when your deployment target requires that.

111

112## Ask for a small validation loop

113

114Behavior-preserving refactors should come with proof. Ask Codex to run the smallest build, preview, test, or simulator check that exercises the screen after each meaningful extraction, then summarize what changed structurally and what stayed intentionally the same.

115

116## Practical tips

117

118### Split first, then debate architecture

119

120If a screen is too large, ask Codex to extract section views before introducing a new abstraction layer. A shorter, more explicit view tree often removes the pressure to add a view model at all.

121

122### Pass the smallest possible interface into each subview

123

124Prefer `let` values, `@Binding`s, and one-purpose callbacks over handing every child view the entire parent model. That makes each extracted section easier to preview and harder to accidentally couple back to the whole screen.

125

126### Ask Codex to call out intentional non-changes

127

128For a safe refactor, it helps when Codex explicitly lists what it did not change: business rules, navigation behavior, persistence, analytics semantics, and user-visible layout. That makes review much faster.

10 39

~~11Why it's needed~~40 - Keep sidebar rows lightweight and native: one icon, one title line, and at

41 most one short secondary line. Do not wrap every row in large custom cards

42 unless there is a strong product reason.

12 43

~~13Menu bar actions, shortcuts, and a dedicated settings window make the feature feel like a real Mac app instead of an iOS screen stretched to desktop.~~44 - Expose important actions through scene-level `commands`, `CommandMenu`,

45 toolbar buttons, and keyboard shortcuts. Do not hide the only path to a

46 critical action behind gestures.

48 - Use `@SceneStorage` for window-scoped UI state, `@AppStorage` for

49 preferences, and explicit parent-owned selection bindings for sidebar/detail

50 coordination.

52 - Prefer system materials, semantic colors, and standard sidebar

53 backgrounds. Add custom styling only to detail or inspector content cards

54 when needed.

56 - Use a narrow AppKit bridge only if SwiftUI cannot express one specific

57 desktop behavior cleanly.

59 - Create or update `script/build_and_run.sh`, run the smallest useful

60 build/run check, and tell me the exact commands you used.

63 Deliver:

65 - the scene structure and main sidebar/detail/inspector views

67 - the menu, toolbar, and keyboard shortcut wiring

69 - the Settings scene and preference state model

88 desktop.

89 - need: State ownership

90 goodDefault: "`@State`, `@SceneStorage`, `@AppStorage`, and explicit selection bindings"

91 why: Codex can keep sidebar selection, inspector visibility, and user

92 preferences predictable without adding a view model by reflex.

93 - need: Native escape hatches

94 goodDefault: "[AppKit](https://developer.apple.com/documentation/appkit) through

95 narrow `NSViewRepresentable` or `NSWindow` bridges"

98 state.

99---

100

101## Start from the Mac scene model

102

103This use case is for turning an app idea into a Mac app shell that feels built for desktop, not stretched from a touch-first stack. Ask Codex to choose the scene model first, then design the main window around stable sidebar selection, a detail surface, and an inspector for secondary controls or metadata.

104

105![A Mac-native sidebar and detail app shell with a selected item in the sidebar and content in the detail pane](https://developers.openai.com/images/codex/use-cases/macos-sidebar-detail-inspector.png)

106

107Use the [Build macOS Apps plugin](https://github.com/openai/plugins/tree/main/plugins/build-macos-apps) when you want Codex to apply that desktop structure and keep the build/run loop shell-first. Its macOS SwiftUI patterns skill is a good fit for scene design, sidebars, inspectors, commands, settings, and small AppKit bridges when SwiftUI stops just short of one Mac-specific behavior.

108

109## Build a sidebar, detail pane, and inspector

110

111Prefer `NavigationSplitView` when the feature benefits from persistent navigation and a stable selected item. Keep sidebar rows native and lightweight, let the sidebar use system backgrounds, and reserve custom cards or dense metadata for the detail pane or inspector.

112

113```swift

114struct LibraryRootView: View {

115 @SceneStorage("LibraryRootView.selection") private var selection: Item.ID?

116 @SceneStorage("LibraryRootView.showInspector") private var showInspector = true

117

118 var body: some View {

119 NavigationSplitView {

120 List(selection: $selection) {

121 ForEach(items) { item in

122 Label(item.title, systemImage: item.systemImage)

123 .tag(item.id)

124 }

125 }

126 .listStyle(.sidebar)

127 .navigationTitle("Library")

128 } detail: {

129 ItemDetailView(selection: selection)

130 .inspector(isPresented: $showInspector) {

131 ItemInspectorView(selection: selection)

132 }

133 }

134 }

135}

136```

137

138If the app needs unusual split sizing, low-level window coordination, or custom responder-chain behavior, ask Codex to keep the SwiftUI shell intact and add only the smallest AppKit bridge required for that one gap.

139

140## Put commands, toolbars, and shortcuts in the desktop layer

141

142Mac users should be able to discover important actions in the menu bar, the toolbar, and keyboard shortcuts. Ask Codex to wire scene-level `commands`, context-sensitive menu items, and toolbar buttons around the same app actions so desktop users do not have to hunt for gesture-only controls.

143

144```swift

145@main

146struct LibraryApp: App {

147 var body: some Scene {

148 WindowGroup {

149 LibraryRootView()

150 }

151 .commands {

152 CommandMenu("Library") {

153 Button("New Item") {

154 // Create a new item.

155 }

156 .keyboardShortcut("n")

157

158 Button("Toggle Inspector") {

159 // Route this command to the focused window or selected item state.

160 }

161 .keyboardShortcut("i", modifiers: [.command, .option])

162 }

163 }

164

165 Settings {

166 LibrarySettingsView()

167 }

168 }

169}

170```

171

172Use `FocusedValue`, scene state, or explicit selection state when a command should apply to the current detail item. If a shortcut would be registered in multiple places, ask Codex to consolidate ownership so the app has one clear command route.

173

174## Keep preferences in `Settings`

175

176For app preferences, use a dedicated `Settings` scene and persist durable user choices with `@AppStorage`. This is usually a better Mac fit than pushing a settings screen inside the main content window.

177

178```swift

179struct LibrarySettingsView: View {

180 @AppStorage("showItemMetadata") private var showItemMetadata = true

181

182 var body: some View {

183 TabView {

184 Form {

185 Toggle("Show Item Metadata", isOn: $showItemMetadata)

186 }

187 .tabItem { Label("General", systemImage: "gearshape") }

188 }

189 .frame(width: 460, height: 260)

190 .scenePadding()

191 }

192}

193```

194

195## Prompt the app concept, then validate the shell

196

197This page works best when your prompt names the app concept, the main content objects, and the primary actions, then asks Codex to build the desktop shell around that workflow first. Have the agent run a small build/run check and summarize the scene structure, command wiring, state ownership, and any AppKit edge it had to bridge.

198

199## Practical tips

200

201### Keep the sidebar native

202

203Use one icon, one title line, and at most one short secondary line in sidebar rows. Move richer cards, counters, and metadata into the detail pane or inspector so the source list stays easy to scan.

204

205### Avoid hiding settings in the main stack

206

207If a user preference affects the whole app, ask Codex to put that control in `Settings` with `@AppStorage` and expose an entry point through the app menu instead of building another pushed settings screen.

208

209### Save AppKit for narrow desktop gaps

210

211If the feature needs open/save panels, first-responder control, or a custom `NSView`, use AppKit as a small edge around a SwiftUI-owned state model rather than rewriting the whole window in AppKit.

96## Add one Logger where debugging gets vague

98This use case is for Mac app flows where "something happened" is too fuzzy to debug from code review alone. Ask Codex to add a few high-signal unified logs around one behavior, run the app, trigger that behavior, and verify from Console or `log stream` that the expected events fired.

100Use the [Build macOS Apps plugin](https://github.com/openai/plugins/tree/main/plugins/build-macos-apps) for that loop. Its macOS telemetry skill is intentionally lightweight: use Apple's `Logger`, choose a clear subsystem/category pair, log action boundaries and state transitions, avoid sensitive payloads, and verify the event after a local build/run instead of assuming the instrumentation is wired correctly.

101

102## Why telemetry is useful for agentic engineering

103

104Good logs give Codex a repeatable feedback loop after each patch. Instead of asking you to manually inspect every window, menu action, or sync transition, the agent can run the app, exercise the flow, inspect filtered logs, and decide the next code change from evidence.

105

106That is especially useful for three agentic loops:

107

108- **Hands-free debug loop:** Codex instruments a suspicious flow, launches the app, clicks the sidebar or triggers a command, reads the emitted log sequence, patches the state update path, and reruns the same flow until the logs and UI behavior agree.

109- **App session collection loop:** Codex adds one event for app launch, window open, sidebar selection, import started, import finished, and import failed, then runs a local session and summarizes the resulting timeline so missing or out-of-order transitions become obvious.

110- **Human-driven capture loop:** Codex launches the app with logging enabled, keeps a focused log stream running while you manually exercise a tricky flow, then inspects the captured session afterward and proposes the next patch from that trace.

111

112## Keep the instrumentation small and filterable

113

114Ask Codex for one logger per feature area, not one permanent log line for every state mutation. Feature categories such as `Windowing`, `Commands`, `MenuBar`, `Sidebar`, `Sync`, or `Import` make logs much easier to filter during the next debugging pass.

115

116```swift

117import OSLog

118

119private let logger = Logger(

120 subsystem: Bundle.main.bundleIdentifier ?? "SampleApp",

121 category: "Sidebar"

122)

123

124@MainActor

125func selectItem(_ item: SidebarItem) {

126 logger.info("Selected sidebar item: \(item.id, privacy: .public)")

127 selection = item.id

128}

129```

130

131Use `info` for concise action and lifecycle events that should remain useful over time, and `debug` for noisier local state details that may be removed or demoted before the task is done. Add signposts only when you are measuring a timing span, not by default.

132

133## Ask Codex to prove the event from logs

134

135The useful part is not just adding `Logger` calls. Ask Codex to run the app, trigger the instrumented flow, and give you the exact Console filter or `log stream` predicate it used plus one or two representative log lines.

136

137```bash

138log stream --style compact --predicate 'subsystem == "com.example.app" && category == "Sidebar"'

139```

140

141If an expected event does not appear, ask Codex to move the log closer to the suspected control path, rerun the same flow, and keep iterating until the logs explain what happened. If the task turns into a crash or backtrace analysis, pivot to the plugin's build/run debugging workflow and keep the telemetry focused on the action boundaries.

142

143## Save a session trace for a later Codex pass

144

145For longer or intermittent bugs, ask Codex to save a focused log stream to a small local trace file, summarize the timeline, and leave that artifact in the workspace so a later Codex run can inspect the same evidence without replaying the whole session from memory. That makes multi-pass debugging easier when you want one agent run to collect a trace and another run to compare behavior before and after a patch.

146

147This also works well when the human needs to drive part of the session. Ask Codex to launch the app in a logging-friendly debug loop, start a filtered capture, wait while you reproduce the issue manually, and then read the saved trace file once you are done.

148

149## Practical tips

150

151### Instrument one feature at a time

152

153Start with one sidebar, window, command, or sync path so the log sequence stays easy to inspect. If that path becomes reliable, Codex can expand the same pattern to neighboring flows.

154

155### Make privacy part of the prompt

156

157Ask Codex to explain every logged identifier and to avoid writing secrets, personal data, or raw content to unified logs. A tiny event vocabulary is usually enough for local debugging.

158

159### Keep sample output in the final summary

160

161Representative log lines make the change much easier to trust than "telemetry was added." Ask Codex to include the filter predicate and a short action timeline so the next agent run can reuse the same verification loop.

52## Introduction

54When you have an existing app and want to iterate fast on the UI, you can use `gpt-5.3-codex-spark` to make small, focused changes to the UI.

55Codex-Spark is our fastest model, optimized for near-instant, real-time coding iteration.

57This works best as a tight loop: one visual note, one focused edit, one browser check, then the next note.

59You can use the [Codex Spark model](https://developers.openai.com/codex/models#gpt-53-codex-spark) for this

60 task. It is available on Pro plans.

62## Pick your model

64For fast UI iteration, start with `gpt-5.3-codex-spark` if you have access to it. It is less capable that our general-purpose models, but is designed for real-time coding iteration. If you don't have access to it, use our latest model with `medium` or `low` reasoning effort.

66That tradeoff is useful for granular UI work. You usually do not need the deepest model to move a button, tune a breakpoint, or adjust a component state. You need a model that responds quickly, understands the local code, edits the right file, and can repeat the loop without making the iteration feel heavy.

68## Development flow

701. Open the existing app and get the relevant route or component visible.

712. Pop out the active Codex conversation into a [floating window](https://developers.openai.com/codex/app/features#floating-pop-out-window) and keep it near your browser, editor, or design preview while you work.

723. Give Codex one specific UI change at a time. Include the route, viewport, current screenshot, target screenshot, or exact product note if you have it.

734. Ask Codex to inspect the current implementation, make the smallest defensible edit, and preserve the app's existing components, tokens, layout primitives, and data flow.

745. Review the result, then send the next small adjustment in the same thread.

76## Write small prompts

78Granular UI prompts should be direct and narrow. A good prompt names the surface, the target change, and the validation you expect.

80If the result is close but not quite right, keep the follow-up equally specific:

82## When to slow down

84Do not keep using the fast loop if the task stops being granular. Switch to a stronger model and a more deliberate prompt when the change needs broad refactoring, a new design system primitive, non-trivial accessibility behavior, or a product decision that affects more than one screen.

86Fast UI iteration works best when Codex is adjusting an already-understood surface, not redesigning the app from scratch.

45## Review your inbox

47Ask Codex to check Gmail, find the messages that deserve a reply, and write drafts in your voice. It can use recent sent mail or approved writing examples for style, then search Slack, docs, project notes, or other tools when the email lacks context on its own.

49Use Codex for the first pass over your inbox: find the emails that need your attention, draft the replies, and bring in the work context that explains the bigger picture.

531. Ask Codex to review Gmail for emails that need your attention.

542. Ask it to use Slack, docs, or project notes for context that explains the bigger picture.

553. Tell Codex which drafts were useful and which emails it should ignore next time.

564. Add an automation when the thread is useful, and pin it if you want fast access later.

60Use the Gmail plugin directly. You can give Codex a broad inbox request, a time window, or a label if you already know the scope. If tone matters, ask Codex to look at recent sent replies or a doc with examples before drafting.

62Use the starter prompt on this page for the first inbox pass. Codex should return a short queue: drafts for emails that need attention, messages that can wait, and the context it used when the answer depended on more than the email thread.

64## Let the thread learn your taste

66Treat the first pass like calibration. If Codex drafts too many replies, tell it which emails were noise. If it misses something important, tell it why that thread mattered. If the tone is off, correct the draft directly.

68Over time, the thread should get better at deciding what needs a draft and what can stay out of your way.

70## Automate email triage on a schedule

72You can create automations to run a scheduled check-in on the same thread. Codex wakes up, checks Gmail and the context sources you named, and posts only when there are emails that need your attention or drafts worth reviewing.

74Once the drafts look useful, ask Codex to keep an eye on Gmail. Email triage is a good job to automate: the drafts are reviewable, and you still decide what gets sent.

76Use this with Codex [automations](https://developers.openai.com/codex/app/automations) after the thread has a good sense of your reply patterns. If Codex finds an email that needs a decision it cannot make, it should flag the question instead of guessing.

78## Organize your inbox

80The Gmail plugin can also help organize your inbox. Keep that as a separate command after you trust the triage.

82For deletion, make the instruction explicit and narrow. Drafting replies is safe to automate for review; destructive cleanup should stay deliberate.

83## Scaffold the app and build loop

85For greenfield work, start with plain prompting. Ask Codex to scaffold a starter iOS SwiftUI app and write a small build-and-launch script you can wire to a `Build` action in a [local environment](https://developers.openai.com/codex/app/local-environments).

87Keep the loop CLI-first. Apple's `xcodebuild` can list schemes and handle build, test, archive, `build-for-testing`, and `test-without-building` actions from the terminal, which lets Codex stay in an agentic loop instead of bouncing into the Xcode GUI.

89If you want a cleaner project generator and you're comfortable with third-party tooling, [Tuist](https://tuist.dev/) is a good next step. It can generate and build Xcode projects without needing the GUI, while still letting Codex build and launch the app from the terminal.

91Use [XcodeBuildMCP](https://www.xcodebuildmcp.com/) once you're inside a full Xcode project and need deeper automation. That's when schemes, targets, simulator control, screenshots, logs, and UI interaction matter enough that plain shell commands stop being the whole story.

93## Leverage skills

95For the first pass, you often don't need a skill or MCP server. Add skills once the work gets specialized or you want stronger SwiftUI conventions baked into the run.

97- [SwiftUI expert](https://github.com/AvdLee/SwiftUI-Agent-Skill) is a strong general-purpose SwiftUI skill with a lot of best practices already baked in.

98- [SwiftUI Pro](https://github.com/twostraws/SwiftUI-Agent-Skill/blob/main/swiftui-pro/SKILL.md) is a broad SwiftUI review skill for modern APIs, maintainability, accessibility, and performance.

100- [Liquid Glass expert](https://github.com/Dimillian/Skills/blob/main/swiftui-liquid-glass/SKILL.md) helps Codex adopt the new iOS 26 Liquid Glass APIs and tune custom components so they fit the latest system design.

101- [SwiftUI performance](https://github.com/Dimillian/Skills/blob/main/swiftui-performance-audit/SKILL.md) helps when a feature feels slow or a SwiftUI view update path looks suspicious. It scans for common SwiftUI mistakes and produces a prioritized report of what to fix and where the biggest gains are.

102- [Swift concurrency expert](https://github.com/Dimillian/Skills/blob/main/swift-concurrency-expert/SKILL.md) helps when cryptic errors and compiler warnings start fighting the change you want to make. On GPT-5.4, you may need it less often, but it's still useful when Swift concurrency diagnostics get noisy.

103- [SwiftUI view refactor](https://github.com/Dimillian/Skills/blob/main/swiftui-view-refactor/SKILL.md) helps keep files smaller and make SwiftUI code more consistent across the repo.

104- [SwiftUI patterns](https://github.com/Dimillian/Skills/blob/main/swiftui-ui-patterns/SKILL.md) helps reach for predictable `@Observable` and `@Environment` architecture patterns as the app grows.

108## Iterate

109

110Once you have a first pass working, or if you're starting from an existing project, you can start iterating on the UI or behavior.

111

112For this part, be specific about what you want to change and how you want to change it.

113

114Make that prompting layer explicit: tell Codex whether it's working in a greenfield repo or an existing Xcode project, which iOS devices or deployment targets must keep working, and what validation loop you expect.

115

116### Example prompt

117

118For example, if you want to add a feature to an existing app, you can ask Codex for a change like this:

119

120## Practical tips

121

122### Start with basics

123

124Start with plain prompting for greenfield work. Ask Codex to scaffold a starter SwiftUI app and write a small build-and-launch script you can wire to a `Build` action in a [local environment](https://developers.openai.com/codex/app/local-environments). For that first pass, you often don't need any skill or MCP server.

125

126### Use a small trustworthy validation loop

127

128After each change, tell Codex to run the narrowest command that actually proves the contract you touched. Expand to broader builds later. This keeps Codex fast without pretending a full app build is required for every edit.

129

130### Keep the loop CLI-first

131

132Keep the loop CLI-first. Apple's `xcodebuild` tool can list schemes and run build, test, archive, `build-for-testing`, and `test-without-building` actions from the terminal, which lets Codex stay in an agentic loop instead of bouncing into the Xcode GUI.

133

134### Leverage XcodeBuildMCP

21 title: Scaffold a Native Mac App

22 body: >-

23 Use the Build macOS Apps plugin to scaffold a starter macOS SwiftUI app and

24 add a project-local `script/build_and_run.sh` entrypoint I can wire to a

25 `Run` action.

31 for package-first apps.

~~9`xcodebuild`, `swift build`, and [App Store Connect CLI](https://asccli.sh/)~~33 - Model Mac scenes explicitly with a main window plus `Settings`,

34 `MenuBarExtra`, or utility windows only when they fit the product.

10 35

~~11Why it's needed~~36 - Prefer desktop-native sidebars, toolbars, menus, keyboard shortcuts, and

37 system materials over iOS-style push navigation.

12 38

~~13Keep local builds, manual archives, script-based notarization, and App Store uploads in a repeatable terminal-first loop.~~39 - Use a narrow AppKit bridge only when SwiftUI cannot express the desktop

40 behavior cleanly.

42 - Keep one small validation loop for each change and tell me exactly which

43 build, launch, or log commands you ran.

46 Deliver:

48 - the app scaffold or requested Mac feature slice

50 - a reusable build-and-run script

52 - the smallest validation steps you ran

54 - any desktop-specific follow-up work you recommend

74 Store uploads in a repeatable terminal-first loop.

75---

77## Scaffold the app and build loop

79For a new Mac app, ask Codex to choose the right scene model first: `WindowGroup`, `Window`, `Settings`, `MenuBarExtra`, or `DocumentGroup`. That keeps the app desktop-native from the first pass instead of growing from an iOS-style `ContentView`.

81Keep the execution loop shell-first. For Xcode projects, use `xcodebuild`. For package-first apps, use `swift build` and a project-local `script/build_and_run.sh` wrapper that stops the old process, builds the app, launches the new artifact, and can optionally expose logs or telemetry.

83If a pure SwiftPM app is a GUI app, bundle and launch it as a `.app` instead of running the raw executable directly. That avoids missing Dock, activation, and bundle-identity issues during local validation.

85## Leverage skills

87Add the [Build macOS Apps plugin](https://github.com/openai/plugins/tree/main/plugins/build-macos-apps) once the work gets more desktop-specific. It covers shell-first build and debug loops, SwiftPM app packaging, native SwiftUI scene and window patterns, AppKit interop, unified logging, test triage, and signing/notarization workflows.

89To learn more about how to install and use plugins and skills, see the [Codex plugins documentation](https://developers.openai.com/codex/plugins) and [skills documentation](https://developers.openai.com/codex/skills).

91## Build desktop-native UI

93Prefer Mac conventions over iOS navigation patterns. Use `NavigationSplitView` for sidebar/detail layouts, explicit `Settings` scenes for preferences, toolbars and commands for discoverable actions, and menu bar extras for lightweight always-available utilities.

95Use system materials, semantic colors, and standard controls first. Add custom window styling, drag regions, or Liquid Glass surfaces only when the product needs a distinct desktop surface.

97If SwiftUI gets close but not all the way there, add the smallest possible AppKit bridge. Good examples are open/save panels, first-responder control, menu validation, drag-and-drop edges, and a wrapped `NSView` for one specialized control.

99## Debug, test, and prepare for shipping

100

101For runtime behavior, ask Codex to add a few `Logger` events around window opening, sidebar selection, menu commands, or background sync, then verify those events with `log stream` after the app launches.

102

103For failing tests, have Codex run the smallest useful `xcodebuild test` or `swift test` scope first and classify whether the issue is compilation, an assertion failure, a crash, a flake, or an environment/setup problem.

104

105When the work shifts from local iteration to distribution, ask Codex to prepare both a manual archive path in Xcode and a script-based archive and notarization path for repeatable shipping. Have it inspect the app bundle, entitlements, and hardened runtime with `codesign` and `plutil`, and use [App Store Connect CLI](https://asccli.sh/) when you want uploads to stay in the terminal too.

106

107## Example prompt

108

109## Practical tips

110

111### Keep scenes explicit

112

113Model the main window, settings window, utility windows, and menu bar extras as separate scene roots instead of hiding the whole app inside one giant view.

114

115### Let system chrome do more of the work

116

117Before creating custom sidebars, toolbars, or materials, check whether standard SwiftUI scene and window APIs already give you the Mac behavior you want.

118

119### Treat AppKit as a narrow edge

120

121Use `NSViewRepresentable`, `NSViewControllerRepresentable`, or a focused `NSWindow` helper for one missing desktop capability, but keep SwiftUI as the source of truth for selection and app state.

122

123### Validate signing and notarization separately from local build success

124

125A successful local launch does not prove the app is signed or notarization-ready. Keep a manual Xcode archive flow for one-off release checks, add a scripted archive and notarization flow for repeatable distribution, and run `codesign` and `plutil` checks when the task is about shipping, not just local iteration.

48 why: The stronger the view, the easier it is for Codex to understand the bigger

49 picture and find signal across sources.

50---

52## Use Codex as a teammate

54Codex gets more useful when it can see the places where your work happens: Slack, Gmail, calendar, project trackers, docs, code, and local notes. Together, those sources show what you work on, who you work with, and which asks or decisions can get buried during the day.

56With that view, one Codex thread can become a proactive teammate. It learns what you care about as you use it, then an automation sends Codex back through the same sources and returns the signal worth interrupting you for.

58## Start a teammate thread

621. Connect the plugins or MCPs for the tools where your work happens.

632. Start a new Codex thread and ask it to check those sources.

643. Tell Codex which items were useful and which were noise.

654. Add an automation to the thread, then pin the thread and watch for notifications.

665. Operate from the same thread: ask questions, get drafts, and tell Codex what action to take next.

70## Run one useful check

72Start with the tools that already hold your work context. For one person, that might be Gmail, Slack, calendar, Notion, GitHub, Linear, and a local notes folder. Ask Codex to check those sources and tell you what needs attention.

74Use the starter prompt on this page for the first check. You can keep it general or make it specific to a workstream, account, launch, team, or project.

76A useful Codex response can look like this:

80<p>

81 <strong>One thing changed.</strong>

82 </p>

83 <p>

84 The renewal prep now says the customer needs security export wording before

85 the partner note goes out. The partner update still frames the work as broad

86 reporting automation.

87 </p>

88 <p>

89 The useful move is to keep Lina's note narrow: say the export helps audit

90 prep, link the renewal prep, and leave the broader automation claim out

91 until Owen signs off.

92 </p>

93 <p>

94 <strong>Priority:</strong> update the partner line before sending the review

95 packet.

96 </p>

100Useful output names the trigger, shows the source, explains the implication, and recommends the next move. When you correct the thread, Codex learns more about how you operate: which sources matter, which owners already have the work, how direct drafts should sound, and what is worth bringing back.

101

102## Turn the thread into an automation

103

104Once the thread becomes useful, ask Codex to keep watching in that same thread. An automation is a scheduled check-in that sends Codex back through the sources you named, then posts a new message if it finds signal worth your attention. It can run hourly, every weekday morning, or at another specific time.

105

106This is the right shape for Codex [automations](https://developers.openai.com/codex/app/automations): test the prompt in a normal thread first, then add an automation to that thread. Because Codex can compact long conversations, the same thread can keep improving with your corrections instead of starting over each morning.

107

108## Operate from the same thread

109

110The teammate becomes more valuable after the alert. Operate as if Codex were your coworker: ask questions in the same thread, then have it turn the signal into a reply, handoff note, or decision brief.

111

112Codex can watch, explain, and draft. You still approve external actions.

34## Introduction

36Computer Use is a strong fit for QA passes because it can see the interface, click through flows, type into fields, and record what fails. That makes it useful for catching both functional bugs and UI issues across realistic user journeys.

38The key is to tell Codex what environment to test, which flows matter most, and what kind of report you want back.

40## How to use

421. Install the [Computer Use plugin](https://developers.openai.com/codex/app/computer-use).

432. Tell Codex which app, build, or environment to test.

443. Name the flows or hero use cases you care about most.

454. Ask for a structured report so the output is easy to triage or hand off.

47You can keep this broad:

49- `@Computer Test my app. Find any major issues and give me a report.`

51Or make it more explicit:

53- `@Computer Test my app in staging. Cover signup, invite a teammate, and upgrade billing. Log every bug with repro steps, expected result, actual result, and severity.`

55If you already maintain a test-plan file in the repo, attach it to the thread or point Codex at it so the QA pass follows your existing flows.

57## Practical tips

59### Be explicit about setup

61If account state, test data, feature flags, or environment choice affect the flow, include that up front. Codex will produce much better results when it knows whether it is testing local, staging, or production-like behavior.

63### Name the issue types you care about

65Call out whether you want Codex to focus on broken functionality, layout issues, confusing copy, visual regressions, or all of the above.

67### Decide whether to stop or continue

69If one blocking issue should end the run, say so. Otherwise, tell Codex to continue through the rest of the flow and collect all non-blocking issues before it summarizes.

71## Good follow-ups

73After the QA pass, keep the same thread open and ask Codex to fix one of the bugs it found, turn the findings into Linear or GitHub-ready drafts, or narrow the next pass to one specific failing flow.

58 compatible packages, and deployment tooling.

59 - need: Routing

60 goodDefault: "[Expo Router](https://docs.expo.dev/router/introduction/)"

61 why: Expo Router keeps navigation file-based and predictable, which helps Codex

62 add screens and flows without inventing a custom routing layer.

63---

65## Start with Expo Go

67Expo is a strong default when you want Codex to move from a mobile-app idea to a

68tested React Native app. The useful loop is `expo start` first, Expo Go

69on a device next, and then a dev client or EAS build only when the app needs

70custom native code, store distribution, or a capability that Expo Go can't run.

72That keeps Codex focused on the app workflow instead of spending the first pass

73on native IDE setup, simulator setup, provisioning, or build configuration.

75## Use the Expo plugin

77Expo published an [Expo plugin](https://docs.expo.dev/skills/) that gives Codex Expo-native guidance for Expo Router, native UI, forms,

78navigation, animations, data fetching, NativeWind setup, Expo modules, dev

79clients, deployment, upgrades, and Codex Run action wiring.

81Use it when Codex is building new Expo screens, adding packages, wiring API

82calls, preparing a dev client, or getting an app ready for TestFlight, App

83Store, Play Store, or EAS Hosting.

85Optionally, add the [Expo MCP Server](https://docs.expo.dev/eas/ai/mcp/) when the task needs current

86Expo documentation lookup, compatible package installation, EAS build and

87workflow operations, screenshots, simulator interaction, React Native DevTools,

88or TestFlight data.

90## Iteration process

941. Ask Codex to inspect the repo and confirm whether it is a new Expo app or an

95 existing Expo project.

962. Start with Expo Router and Expo Go, and use `npx expo install` when adding

97 Expo packages.

983. Ask Codex to build one complete workflow with native-feeling navigation,

99 loading states, empty states, and error states.

1004. Verify on the fastest available path, such as Expo Go on a device or a

101 simulator, then move to a dev client or EAS only when needed.

56## Introduction

58When your codebase has accumulated unused code, duplicated logic, stale abstractions, large files, or legacy patterns that make every change more expensive than it should be, you should consider reducing the engineering debt with a refactor. Refactoring is about improving the shape of the existing system without turning it into a stack migration.

60Codex is useful here because it can first map the messy area, then land the cleanup in small reviewable passes: deleting unused paths, untangling large modules, collapsing duplicate paths, modernizing old framework patterns, and tightening validation around each pass.

62The goal is to improve the current codebase in place:

641. Remove unused code, stale helpers, old flags, and compatibility shims that are no longer needed.

652. Shrink noisy modules by extracting helpers, splitting components, or moving side effects to clearer boundaries.

663. Replace legacy patterns with the repo's current conventions: newer framework primitives, clearer types, simpler state flow, or standard library utilities.

674. Keep public behavior stable while making the next change cheaper.

69## How to use

711. Ask Codex to map the area before editing: noisy modules, duplicated logic, unused code, tests, public contracts, and any old patterns that the repo has outgrown.

722. Pick one cleanup theme at a time: remove unused code, simplify control flow, modernize an outdated pattern, or split a large file into smaller owned pieces.

733. Before Codex patches files, have it state the current behavior, the structural improvement it wants to make, and the smallest check that should prove behavior stayed stable.

744. Review and run the smallest useful check after each pass instead of batching the whole cleanup into one diff.

755. Keep stack changes, dependency migrations, and architecture moves as separate tasks unless they're required to finish the cleanup.

77You can use Plan mode to create a plan for the refactor before starting the

78 work.

80## Leverage ExecPlans

82The [code modernization cookbook](https://developers.openai.com/cookbook/examples/codex/code_modernization) introduces ExecPlans: documents that let Codex keep an overview of the cleanup, spell out the intended end state, and log validation after each pass.

83They're useful when the refactor spans more than one module or takes more than one session. Use them to record deletions, pattern updates, contracts that had to stay stable, and what's still deferred.

85## Use skills for repeatable patterns

87[Skills](https://developers.openai.com/codex/skills) are useful when the same cleanup rules repeat across repos, services, or teams. Use framework-specific skills when available, add security and CI skills around risky cleanups, and create a team skill when you have a proven checklist for unused-code removal, module extraction, or legacy-pattern modernization.

88If you end up doing the same modernization pass across more than one codebase, Codex can help turn the first successful pass into a reusable skill.

70## Find the work hidden in Slack

72Slack is often where a request starts, but not where the full context lives. A teammate might ask for a reply in a DM, clarify the real action in a thread, link a doc in a channel, and resolve the issue later without mentioning you again.

74Use this workflow when you want Codex to read the Slack context, check whether the ask is still live, and return the few items that actually need your attention. The goal is to get a ranked action queue: what needs a reply, a decision, a person to contact, a doc update, or a handoff.

76## Run the triage pass

801. Give Codex a time window, workstream, person, channel, or topic.

812. Ask it to search DMs, group DMs, channel mentions, and relevant thread replies.

823. Have Codex read the latest thread tail before calling an item unresolved.

834. Ask for a ranked queue sorted by urgency and impact.

845. Ask Codex to draft the reply, handoff, or follow-up task.

88After trying this and tweaking the flow to match your needs, you can turn it into a [thread automation](https://developers.openai.com/codex/app/automations#thread-automations) by asking Codex to do the same thing on a schedule.

90## Ask for the right output

92A useful triage result should explain why each item is still live. It should also skip old asks that someone answered later in the thread.

94You should expect to see something like this:

98<p>

99 <strong>Top action item:</strong> Priya is asking for concrete customer

100 examples, not just more ideas.

101 </p>

102 <p>

103 <strong>Why it matters:</strong> the launch update needs real people the

104 team can contact this week.

105 </p>

106 <p>

107 <strong>Evidence:</strong> the original channel message asked for use cases,

108 but the thread later says "please DM me if you have leads."

109 </p>

110 <p>

111 <strong>Next step:</strong> reply with two named leads, or say you can be

112 the example if that is more useful.

113 </p>

114

115

116

117Good output makes the distinction explicit: an idea is different from a lead, a live ask is different from an FYI, and a request you already answered shouldn't stay in the queue.

118

119If you get too much noise or too few actionable items, tweak the prompt and if needed, mention specific slack channels you want Codex to pay attention to.

120

121## Draft the follow-up

123Once the queue is right, keep the action in the same thread. Ask Codex to draft a reply or handoff from the evidence it already gathered:

52## Introduction

54Documentation is easiest to keep current when it is updated alongside source changes, not weeks later. Codex can inspect changed code, tests, release notes, linked issues, and pull request context, then draft a scoped docs update that matches the existing structure.

56Use this workflow for developer docs, README updates, changelog drafts, migration notes, runbooks, or anything else that needs to track behavior that changes frequently.

58## How to use

621. Start from the change you need to document.

64 Share the branch, pull request, commit, issue, or files. If the docs are public, say explicitly that unpublished roadmap, private customer details, and internal-only context should stay out.

662. Ask Codex to map the affected docs.

68 Have it search existing docs for feature names, config keys, commands, examples, and related terms before drafting.

703. Update the smallest useful docs surface.

72 Codex should preserve the current page structure, terminology, cross-links, and frontmatter. It should avoid broad rewrites when a precise note, example, or section update is enough.

744. Verify the changes.

76 Ask Codex to run formatting and docs checks that fit the repo, then summarize the evidence behind each user-facing claim.

78## What to give Codex

80| Source | Why it helps |

81| ------------------------------------ | -------------------------------------------------------------------------- |

82| Changed code and tests | Lets Codex analyze actual behavior to draft focused documentation updates. |

83| Public release notes or product docs | Helps Codex match public terminology, availability, and feature status. |

84| Pull request or issue context | Explains why the change happened and which user-facing behavior matters. |

85| Local docs checks | Gives Codex a concrete definition of done before the docs are published. |

87Adding more context such as public release notes lets Codex avoid including private context or updates that are not yet public.

89## Make the workflow repeatable

91For a repo-wide convention, add documentation expectations to [AGENTS.md](https://developers.openai.com/codex/guides/agents-md). For example:

93```md

94## Documentation

96- When user-facing behavior changes, check whether docs, examples, or changelogs need updates.

97- Public docs must only include public information or behavior visible in this repo.

98- Preserve existing terminology and frontmatter.

99- Run the docs formatting and build checks before final handoff.

100```

101

102If the process has more steps, turn it into a [skill](https://developers.openai.com/codex/skills) so future Codex threads can follow the same source-checking, drafting, and verification loop. See [Save workflows as skills](https://developers.openai.com/codex/use-cases/reusable-codex-skills) that shares more details on this pattern.

103

104You can also turn this workflow into a [thread automation](https://developers.openai.com/codex/app/automations#thread-automations) by asking Codex to run it on a schedule, asking to fetch all the recent PRs from GitHub to automatically keep docs up-to-date, for example on a weekly basis:

34## Introduction

36You can let Codex operate an app the same way you would: by clicking, seeing, and typing. [Computer Use](https://developers.openai.com/codex/app/computer-use) is useful when the task lives inside a normal app UI, even if that app does not have a dedicated plugin.

38This works especially well for tasks that jump between apps or windows, such as collecting notes, updating a system of record, copying details from one place to another, or drafting a reply after checking context in a few different apps.

40## How to use

421. Install the [Computer Use plugin](https://developers.openai.com/codex/app/computer-use).

432. Start your request with `@Computer`, or mention a specific app such as `@Slack` or `@Messages`.

443. Describe the task and the outcome you want.

454. Approve access when Codex needs it, then let it continue the task in the background.

47If you mention a specific app and a plugin exists for that app, Codex may prefer the plugin over Computer Use. That is usually what you want. If no plugin exists, Codex can fall back to Computer Use and operate the app directly.

49For example:

51- `@Computer Play some music to help me focus.`

52- `@Computer Help me add my interview notes from Notes to Ashby.`

53- `@Computer Go through my Slack and add reminders for everything I need to do by end of day.`

55## Practical tips

57### Choose the browser Codex should use

59Computer Use takes control of the app it is operating. If you want to keep working in one browser while Codex browses in another, tell it which browser to use. You can also set a default in [customization](https://developers.openai.com/codex/concepts/customization), for example: "When using Computer Use for web browsing tasks, default to Chrome instead of Safari."

61### Avoid parallel runs in the same app

63Do not run two Computer Use tasks against the same app at the same time. That makes it much harder for Codex to keep stable context about the current window and state.

65### Stay signed in

67For smoother runs, make sure you are already signed in to the apps and services you want Codex to use. If your Mac locks while Computer Use is running, the activity will stop.

69## Good follow-ups

71Once the task finishes, keep the same thread open if you want Codex to summarize what it changed, double-check the result, or turn the workflow into a more repeatable pattern through [customization](https://developers.openai.com/codex/concepts/customization).

60## Introduction

62Product teams often collect feedback from various sources, such as Slack threads, Linear issues, Google Drive docs or sheets, or customer-call notes. Sometimes, they have clear user stories illustrating a problem they want to solve, and sometimes, the context lives in those sources.

64Codex can gather this context and turn it into a UI mock for a feature that would solve the problem, and once validated, can be implemented into the product.

66## Generate visual truth

68If you have a clear user story, you can start with that. If not, you can have a discussion with Codex first, gathering context from different sources and synthesizing it into a user story.

70Then, you can ask Codex to use ImageGen to create a few mock directions. The mocks should preserve the product's information architecture and design-system constraints.

72If helpful, you can provide screenshots of the current UI or a Figma file as reference.

74Do this until you are satisfied with the mock. The more scoped the changes are, the more likely Codex is to generate a mock that can be implemented directly.

76## Move from mock to prototype

78Use the final mock image that you want Codex to implement. Re-attach this image in a new turn rather than continuing the conversation directly.

79You can then ask Codex to implement the mock – optionally using the [Build Web Apps plugin](https://developers.openai.com/codex/plugins/build-web-apps) if you're building a web app – to turn it into a working prototype:

60## Run operations you can audit

62If you have repeatable operations you need to run regularly, such as giving access to a user, applying a batch update, or calling a script with different parameters for example, you can use Codex to automate it and give you an auditable output.

64Use this workflow when Codex should run a repeatable operation and show you what happened with an artifact that counts as verification.

66## Describe the task and inputs

701. Give Codex the input table, files, tickets, or other list it should batch run the process on.

712. Point it to the approval source or policy that defines the allowed scope, if applicable.

723. Tell Codex which script, API, skill, CLI, or app workflow should do the work.

734. Optionally, ask for a dry run when the workflow supports one.

745. Ask Codex to run the batch operation and record one success or failure row per item.

78Keep the scope narrow, and add instructions for Codex to run the operation only when it has all the required inputs.

79If a row is missing a required field, Codex should flag that row instead of guessing.

81Connect the tools you use to run the operation with [plugins](https://developers.openai.com/codex/plugins), for example your ticketing system or your spreadsheet with list items.

83## Require proof to verify the result

85A useful operations run includes an artifact that you or a teammate can inspect, such as a result CSV, a log file, a dashboard link, a screenshot, a PR check, or any other proof that the operation was successful. When using the Codex app, you can inspect this [artifact](https://developers.openai.com/codex/app/artifacts) directly in the artifact viewer after the run to verify the result.

87## Turn the run into a reusable workflow

89After the first successful run, ask Codex to capture the repeatable parts. For common workflows, this can become a [skill](https://developers.openai.com/codex/skills), or an [automation](https://developers.openai.com/codex/app/automations) that runs on a schedule.

91For scheduled operations, use an automation only after the manual run produces reliable output. Keep sensitive actions that might affect access or data permanently draft-only unless you explicitly want Codex to take them.
