40### Use plugins locally

41 

42For the fastest setup, use the built-in `@plugin-creator` skill to scaffold a

43local plugin.

44 

45![plugin-creator skill in Codex](/images/codex/plugins/plugin-creator.png)

46 

47It creates the required `.codex-plugin/plugin.json` manifest and

48can also generate a local marketplace entry for testing.

49 

50If you already have a plugin from another ecosystem or a plugin you built

51yourself, you can add it to your local marketplace with `@plugin-creator`.

52 

53![how to invoke the plugin-creator skill](/images/codex/plugins/plugin-creator-invoke.png)

54 

55In the plugin directory, you can also load your own local marketplace with a

56custom marketplace name and browse the plugins there.

57 

58![custom local marketplace in the plugin directory](/images/codex/plugins/codex-local-plugin-light.png)

59 

60#### Install a local plugin manually

61 

62Use a repo marketplace or a personal marketplace, depending on who should be

63able to access the plugin.

64 

65Add a marketplace file at `$REPO_ROOT/.agents/plugins/marketplace.json`

66and store your plugins under `$REPO_ROOT/plugins/`.

67 

68**Repo marketplace example**

69 

70Step 1: Copy the plugin folder into `$REPO_ROOT/plugins/my-plugin`.

71 

72```

73mkdir -p ./plugins

74cp -R /absolute/path/to/my-plugin ./plugins/my-plugin

75```

76 

77Step 2: Add or update `$REPO_ROOT/.agents/plugins/marketplace.json` so

78that `source.path` points to that plugin directory with a `./`-prefixed

79relative path:

80 

81```

82{

83 "name": "local-repo",

84 "plugins": [

85 {

86 "name": "my-plugin",

87 "source": {

88 "source": "local",

89 "path": "./plugins/my-plugin"

90 },

91 "policy": {

92 "installation": "AVAILABLE",

93 "authentication": "ON_INSTALL"

94 },

95 "category": "Productivity"

96 }

97 ]

98}

99```

100 

101Step 3: Restart Codex and verify that the plugin appears.

102 

103Add a marketplace file at `~/.agents/plugins/marketplace.json` and store

104your plugins under `~/.codex/plugins/`.

105 

106**Personal marketplace example**

107 

108Step 1: Copy the plugin folder into `~/.codex/plugins/my-plugin`.

109 

110```

111mkdir -p ~/.codex/plugins

112cp -R /absolute/path/to/my-plugin ~/.codex/plugins/my-plugin

113```

114 

115Step 2: Add or update `~/.agents/plugins/marketplace.json` so that the

116plugin entry’s `source.path` points to that directory.

117 

118Step 3: Restart Codex and verify that the plugin appears.

119 

120The marketplace file points to the plugin location, so those directories are

121examples rather than fixed requirements. Codex resolves `source.path` relative

122to the marketplace root, not relative to the `.agents/plugins/` folder. See

123[Marketplace metadata](#marketplace-metadata) for the file format.

124 

125After you change the plugin, update the plugin directory that your marketplace

126entry points to and restart Codex so the local install picks up the new files.

127 

128### Marketplace metadata

129 

130If you maintain a repo marketplace, define it in

131`$REPO_ROOT/.agents/plugins/marketplace.json`. For a personal marketplace, use

132`~/.agents/plugins/marketplace.json`. A marketplace file controls plugin

133ordering and install policies in Codex-facing catalogs. Before you add a plugin

134to a marketplace, make sure its `version`, publisher metadata, and

135install-surface copy are ready for other developers to see.

136 

137```

138{

139 "name": "openai-curated",

140 "interface": {

141 "displayName": "ChatGPT Official"

142 },

144 {

152 "authentication": "ON_INSTALL"

153 },

154 "category": "Productivity"

155 }

156 ]

157}

158```

159 

160- Use top-level `name` to identify the marketplace.

161- Use `interface.displayName` for the marketplace title shown in Codex.

162- Point each plugin entry’s `source.path` at the plugin directory you want

163 Codex to load. For repo installs, that often lives under

164 `./plugins/`. For personal installs, it often lives under

165 `~/.codex/plugins/`.

166- Keep `source.path` relative to the marketplace root, start it with `./`, and

167 keep it inside that root.

168- Always include `policy.installation`, `policy.authentication`, and

169 `category` on each plugin entry.

170- Use `policy.installation` values such as `AVAILABLE`,

171 `INSTALLED_BY_DEFAULT`, or `NOT_AVAILABLE`.

172- Use `policy.authentication` to decide whether auth happens on install or

173 first use.

174 45 

175The marketplace controls where Codex loads the plugin from. `source.path` can46### Install and use a plugin

176point somewhere else if your plugin lives outside those example directories. A

177marketplace file can live in the repo where you are developing the plugin or in

178a separate marketplace repo, and one marketplace file can point to one plugin

179or many.

180 47 

181### How Codex uses marketplaces48Once you open the plugin directory:

182 49 

183A plugin marketplace is a JSON catalog of plugins that Codex can read and501. Search or browse for a plugin, then open its details.

184install.512. Select the install button. In the app, select the plus button or

52 **Add to Codex**. In the CLI, select `Install plugin`.

533. If the plugin needs an external app, connect it when prompted. Some plugins

54 ask you to authenticate during install. Others wait until the first time you

55 use them.

564. After installation, start a new thread and ask Codex to use the plugin.

185 57 

186Codex can read marketplace files from:58After you install a plugin, you can use it directly in the prompt window:

187 59 

188- the curated marketplace that powers the official Plugin Directory60![Codex Plugins page](/images/codex/plugins/plugin-github-invoke.png)

189- a repo marketplace at `$REPO_ROOT/.agents/plugins/marketplace.json`

190- a personal marketplace at `~/.agents/plugins/marketplace.json`

191 61 

192You can install any plugin exposed through a marketplace. Codex installs62Describe the task directly

193plugins into

194`~/.codex/plugins/cache/$MARKETPLACE_NAME/$PLUGIN_NAME/$VERSION/`. For local

195plugins, `$VERSION` is `local`, and Codex loads the installed copy from that

196cache path rather than directly from the marketplace entry.

197 63 

198You can enable or disable each plugin individually. Codex stores each plugin’s64 Ask for the outcome you want, such as "Summarize unread Gmail threads

199on or off state in `~/.codex/config.toml`.65 from today" or "Pull the latest launch notes from Google Drive."

200 66 

201## Build and distribute plugins67 Use this when you want Codex to choose the right installed tools for the

68 task.

202 69 

203### When to create a plugin70Choose a specific plugin

204 71 

205Use local skills when:72 Type <code>@</code> to invoke the plugin or one of its bundled skills

73 explicitly.

206 74 

207- You are iterating on one repo or one workflow.75 Use this when you want to be specific about which plugin or skill Codex

208- The behavior is personal or project-specific.76should use. See [Codex app commands](https://developers.openai.com/codex/app/commands) and

209- You are experimenting before you package something reusable.77[Skills](https://developers.openai.com/codex/skills).

211Use plugins when:79### How permissions and data sharing work

212 80 

213- You want the same skills or app integrations available across teams or81Installing a plugin makes its workflows available in Codex, but your existing

214 projects.82[approval settings](https://developers.openai.com/codex/agent-approvals-security) still apply. Any

215- You want to bundle skills, MCP config, and app integrations into one83connected external services remain subject to their own authentication,

216 installable unit.84privacy, and data-sharing policies.

217- You want a stable, versioned package for teammates or a marketplace.

218 85 

219Start local, then package the workflow as a plugin when you are ready to share86- Bundled skills are available as soon as you install the plugin.

220it.87- If a plugin includes apps, Codex may prompt you to install or sign in to

88 those apps in ChatGPT during setup or the first time you use them.

89- If a plugin includes MCP servers, they may require additional setup or

90 authentication before you can use them.

91- When Codex sends data through a bundled app, that app's terms and privacy

92 policy apply.

221 93 

222### Plugin structure94### Remove or turn off a plugin

223 95 

224Every plugin has a manifest at `.codex-plugin/plugin.json`. It can also include96To remove a plugin, reopen it from the plugin browser and select

238 - .app.json Optional: app or connector mappings

239 - .mcp.json Optional: MCP server configuration

240 - assets/ Optional: icons, logos, screenshots

241 

242Only `plugin.json` belongs in `.codex-plugin/`. Keep `skills/`, `assets/`,

243`.mcp.json`, and `.app.json` at the plugin root.

244 

245Published plugins typically use a richer manifest than the minimal example that

246appears in quick-start scaffolds. The manifest has three jobs:

247 

248- Identify the plugin.

249- Point to bundled components such as skills, apps, or MCP servers.

250- Provide install-surface metadata such as descriptions, icons, and legal links.

251 

252Here’s a complete manifest example:

253 

254```

255{

256 "name": "my-plugin",

257 "version": "0.1.0",

258 "description": "Bundle reusable skills and app integrations.",

261 "email": "team@example.com",

262 "url": "https://example.com"

263 },

264 "homepage": "https://example.com/plugins/my-plugin",

265 "repository": "https://github.com/example/my-plugin",

266 "license": "MIT",

267 "keywords": ["research", "crm"],

268 "skills": "./skills/",

269 "mcpServers": "./.mcp.json",

270 "apps": "./.app.json",

271 "interface": {

272 "displayName": "My Plugin",

273 "shortDescription": "Reusable skills and apps",

274 "longDescription": "Distribute skills and app integrations together.",

275 "developerName": "Your team",

276 "category": "Productivity",

277 "capabilities": ["Read", "Write"],

278 "websiteURL": "https://example.com",

279 "privacyPolicyURL": "https://example.com/privacy",

280 "termsOfServiceURL": "https://example.com/terms",

281 "defaultPrompt": [

283 "Use My Plugin to triage new customer follow-ups."

284 ],

285 "brandColor": "#10A37F",

286 "composerIcon": "./assets/icon.png",

287 "logo": "./assets/logo.png",

288 "screenshots": ["./assets/screenshot-1.png"]

289 }

290}

291```

292 

293`.codex-plugin/plugin.json` is the required entry point. The other manifest

294fields are optional, but published plugins commonly use them.

295 

296### Create your first plugin

297 

298Start with a minimal plugin that packages one skill.

299 

3001. Create a plugin folder with a manifest at `.codex-plugin/plugin.json`.

301 

302```

303mkdir -p my-first-plugin/.codex-plugin

304```108```

305 109 

306`my-first-plugin/.codex-plugin/plugin.json`110## Build your own plugin

307 

308```

309{

310 "name": "my-first-plugin",

311 "version": "1.0.0",

312 "description": "Reusable greeting workflow",

313 "skills": "./skills/"

314}

315```

316 

317Use a stable plugin `name` in kebab-case. Codex uses it as the plugin

318identifier and component namespace.

319 

3202. Add a skill under `skills/<skill-name>/SKILL.md`.

321 

322```

323mkdir -p my-first-plugin/skills/hello

324```

325 

326`my-first-plugin/skills/hello/SKILL.md`

327 

328```

329name: hello

330description: Greet the user with a friendly message.

331 

332Greet the user warmly and ask how you can help.

333```

334 

3353. Follow [Use plugins locally](#use-plugins-locally) to load the plugin in

336 Codex.

337 

338From there, you can add MCP config, app integrations, or marketplace metadata

339as needed.

340 

341### Manifest fields

342 

343Use the top-level fields to define package metadata and point to bundled

344components:

345 

346- `name`, `version`, and `description` identify the plugin.

347- `author`, `homepage`, `repository`, `license`, and `keywords` provide

348 publisher and discovery metadata.

349- `skills`, `mcpServers`, and `apps` point to bundled components relative to

350 the plugin root.

351- `interface` controls how install surfaces present the plugin.

352 

353Use the `interface` object for install-surface metadata:

354 

355- `displayName`, `shortDescription`, and `longDescription` control the title and

356 descriptive copy.

357- `developerName`, `category`, and `capabilities` add publisher and capability

358 metadata.

359- `websiteURL`, `privacyPolicyURL`, and `termsOfServiceURL` provide external

360 links.

361- `defaultPrompt`, `brandColor`, `composerIcon`, `logo`, and `screenshots`

362 control starter prompts and visual presentation.

363 

364### Path rules

365 

366- Keep manifest paths relative to the plugin root and start them with `./`.

367- Store visual assets such as `composerIcon`, `logo`, and `screenshots` under

368 `./assets/` when possible.

369- Use `skills` for bundled skill folders, `apps` for `.app.json`, and

370 `mcpServers` for `.mcp.json`.

371 

372### Publish official public plugins

373 

374Adding plugins to the official Plugin Directory is coming soon.

1# Build plugins

2 

3This page is for plugin authors. If you want to browse, install, and use

4plugins in Codex, see [Plugins](https://developers.openai.com/codex/plugins). If you are still iterating on

5one repo or one personal workflow, start with a local skill. Build a plugin

6when you want to share that workflow across teams, bundle app integrations or

7MCP config, or publish a stable package.

8 

9## Create a plugin with `$plugin-creator`

10 

11For the fastest setup, use the built-in `$plugin-creator` skill.

12 

13![plugin-creator skill in Codex](/images/codex/plugins/plugin-creator.png)

14 

15It scaffolds the required `.codex-plugin/plugin.json` manifest and can also

16generate a local marketplace entry for testing. If you already have a plugin

17folder, you can still use `$plugin-creator` to wire it into a local

18marketplace.

19 

20![how to invoke the plugin-creator skill](/images/codex/plugins/plugin-creator-invoke.png)

21 

22### Build your own curated plugin list

23 

24A marketplace is a JSON catalog of plugins. `$plugin-creator` can generate one

25for a single plugin, and you can keep adding entries to that same marketplace

26to build your own curated list for a repo, team, or personal workflow.

27 

28In Codex, each marketplace appears as a selectable source in the plugin

29directory. Use `$REPO_ROOT/.agents/plugins/marketplace.json` for a repo-scoped

30list or `~/.agents/plugins/marketplace.json` for a personal list. Add one

31entry per plugin under `plugins[]`, point each `source.path` at the plugin

32folder with a `./`-prefixed path relative to the marketplace root, and set

33`interface.displayName` to the label you want Codex to show in the marketplace

34picker. Then restart Codex. After that, open the plugin directory, choose your

35marketplace, and browse or install the plugins in that curated list.

36 

37You don't need a separate marketplace per plugin. One marketplace can expose a

38single plugin while you are testing, then grow into a larger curated catalog as

39you add more plugins.

40 

41![custom local marketplace in the plugin directory](/images/codex/plugins/codex-local-plugin-light.png)

42 

43### Create a plugin manually

44 

45Start with a minimal plugin that packages one skill.

46 

471. Create a plugin folder with a manifest at `.codex-plugin/plugin.json`.

48 

49```bash

50mkdir -p my-first-plugin/.codex-plugin

51```

52 

53`my-first-plugin/.codex-plugin/plugin.json`

54 

55```json

56{

57 "name": "my-first-plugin",

58 "version": "1.0.0",

59 "description": "Reusable greeting workflow",

60 "skills": "./skills/"

61}

62```

63 

64Use a stable plugin `name` in kebab-case. Codex uses it as the plugin

65identifier and component namespace.

66 

672. Add a skill under `skills/<skill-name>/SKILL.md`.

68 

69```bash

70mkdir -p my-first-plugin/skills/hello

71```

72 

73`my-first-plugin/skills/hello/SKILL.md`

74 

75```md

76---

77name: hello

78description: Greet the user with a friendly message.

79---

80 

81Greet the user warmly and ask how you can help.

82```

83 

843. Add the plugin to a marketplace. Use `$plugin-creator` to generate one, or

85 follow [Build your own curated plugin list](#build-your-own-curated-plugin-list)

86 to wire the plugin into Codex manually.

87 

88From there, you can add MCP config, app integrations, or marketplace metadata

89as needed.

90 

91### Install a local plugin manually

92 

93Use a repo marketplace or a personal marketplace, depending on who should be

94able to access the plugin or curated list.

95 

96 Add a marketplace file at `$REPO_ROOT/.agents/plugins/marketplace.json`

97 and store your plugins under `$REPO_ROOT/plugins/`.

98 

99 **Repo marketplace example**

100 

101 Step 1: Copy the plugin folder into `$REPO_ROOT/plugins/my-plugin`.

102 

103```bash

104mkdir -p ./plugins

105cp -R /absolute/path/to/my-plugin ./plugins/my-plugin

106```

107 

108 Step 2: Add or update `$REPO_ROOT/.agents/plugins/marketplace.json` so

109 that `source.path` points to that plugin directory with a `./`-prefixed

110 relative path:

111 

112```json

113{

114 "name": "local-repo",

115 "plugins": [

116 {

117 "name": "my-plugin",

118 "source": {

119 "source": "local",

120 "path": "./plugins/my-plugin"

121 },

122 "policy": {

123 "installation": "AVAILABLE",

124 "authentication": "ON_INSTALL"

125 },

126 "category": "Productivity"

127 }

128 ]

129}

130```

131 

132 Step 3: Restart Codex and verify that the plugin appears.

133 

134 Add a marketplace file at `~/.agents/plugins/marketplace.json` and store

135 your plugins under `~/.codex/plugins/`.

136 

137 **Personal marketplace example**

138 

139 Step 1: Copy the plugin folder into `~/.codex/plugins/my-plugin`.

140 

141```bash

142mkdir -p ~/.codex/plugins

143cp -R /absolute/path/to/my-plugin ~/.codex/plugins/my-plugin

144```

145 

146 Step 2: Add or update `~/.agents/plugins/marketplace.json` so that the

147 plugin entry's `source.path` points to that directory.

148 

149 Step 3: Restart Codex and verify that the plugin appears.

150 

151The marketplace file points to the plugin location, so those directories are

152examples rather than fixed requirements. Codex resolves `source.path` relative

153to the marketplace root, not relative to the `.agents/plugins/` folder. See

154[Marketplace metadata](#marketplace-metadata) for the file format.

155 

156After you change the plugin, update the plugin directory that your marketplace

157entry points to and restart Codex so the local install picks up the new files.

158 

159### Marketplace metadata

160 

161If you maintain a repo marketplace, define it in

162`$REPO_ROOT/.agents/plugins/marketplace.json`. For a personal marketplace, use

163`~/.agents/plugins/marketplace.json`. A marketplace file controls plugin

164ordering and install policies in Codex-facing catalogs. It can represent one

165plugin while you are testing or a curated list of plugins that you want Codex

166to show together under one marketplace name. Before you add a plugin to a

167marketplace, make sure its `version`, publisher metadata, and install-surface

168copy are ready for other developers to see.

169 

170```json

171{

172 "name": "local-example-plugins",

173 "interface": {

174 "displayName": "Local Example Plugins"

175 },

176 "plugins": [

177 {

178 "name": "my-plugin",

179 "source": {

180 "source": "local",

181 "path": "./plugins/my-plugin"

182 },

183 "policy": {

184 "installation": "AVAILABLE",

185 "authentication": "ON_INSTALL"

186 },

187 "category": "Productivity"

188 },

189 {

190 "name": "research-helper",

191 "source": {

192 "source": "local",

193 "path": "./plugins/research-helper"

194 },

195 "policy": {

196 "installation": "AVAILABLE",

197 "authentication": "ON_INSTALL"

198 },

199 "category": "Productivity"

200 }

201 ]

202}

203```

204 

205- Use top-level `name` to identify the marketplace.

206- Use `interface.displayName` for the marketplace title shown in Codex.

207- Add one object per plugin under `plugins` to build a curated list that Codex

208 shows under that marketplace title.

209- Point each plugin entry's `source.path` at the plugin directory you want

210 Codex to load. For repo installs, that often lives under `./plugins/`. For

211 personal installs, a common pattern is `./.codex/plugins/<plugin-name>`.

212- Keep `source.path` relative to the marketplace root, start it with `./`, and

213 keep it inside that root.

214- Always include `policy.installation`, `policy.authentication`, and

215 `category` on each plugin entry.

216- Use `policy.installation` values such as `AVAILABLE`,

217 `INSTALLED_BY_DEFAULT`, or `NOT_AVAILABLE`.

218- Use `policy.authentication` to decide whether auth happens on install or

219 first use.

220 

221The marketplace controls where Codex loads the plugin from. `source.path` can

222point somewhere else if your plugin lives outside those example directories. A

223marketplace file can live in the repo where you are developing the plugin or in

224a separate marketplace repo, and one marketplace file can point to one plugin

225or many.

226 

227### How Codex uses marketplaces

228 

229A plugin marketplace is a JSON catalog of plugins that Codex can read and

230install.

231 

232Codex can read marketplace files from:

233 

234- the curated marketplace that powers the official Plugin Directory

235- a repo marketplace at `$REPO_ROOT/.agents/plugins/marketplace.json`

236- a personal marketplace at `~/.agents/plugins/marketplace.json`

237 

238You can install any plugin exposed through a marketplace. Codex installs

239plugins into

240`~/.codex/plugins/cache/$MARKETPLACE_NAME/$PLUGIN_NAME/$VERSION/`. For local

241plugins, `$VERSION` is `local`, and Codex loads the installed copy from that

242cache path rather than directly from the marketplace entry.

243 

244You can enable or disable each plugin individually. Codex stores each plugin's

245on or off state in `~/.codex/config.toml`.

246 

247## Package and distribute plugins

248 

249### Plugin structure

250 

251Every plugin has a manifest at `.codex-plugin/plugin.json`. It can also include

252a `skills/` directory, an `.app.json` file that points at one or more apps or

253connectors, and assets used to present the plugin across supported surfaces.

254 

255- my-plugin/

256 

257 - .codex-plugin/

258 

259 - plugin.json Required: plugin manifest

260 - skills/

261 

262 - my-skill/

263 

264 - SKILL.md Optional: skill instructions

265 - .app.json Optional: app or connector mappings

266 - .mcp.json Optional: MCP server configuration

267 - assets/ Optional: icons, logos, screenshots

268 

269Only `plugin.json` belongs in `.codex-plugin/`. Keep `skills/`, `assets/`,

270`.mcp.json`, and `.app.json` at the plugin root.

271 

272Published plugins typically use a richer manifest than the minimal example that

273appears in quick-start scaffolds. The manifest has three jobs:

274 

275- Identify the plugin.

276- Point to bundled components such as skills, apps, or MCP servers.

277- Provide install-surface metadata such as descriptions, icons, and legal

278 links.

279 

280Here's a complete manifest example:

281 

282```json

283{

284 "name": "my-plugin",

285 "version": "0.1.0",

286 "description": "Bundle reusable skills and app integrations.",

287 "author": {

288 "name": "Your team",

289 "email": "team@example.com",

290 "url": "https://example.com"

291 },

292 "homepage": "https://example.com/plugins/my-plugin",

293 "repository": "https://github.com/example/my-plugin",

294 "license": "MIT",

295 "keywords": ["research", "crm"],

296 "skills": "./skills/",

297 "mcpServers": "./.mcp.json",

298 "apps": "./.app.json",

299 "interface": {

300 "displayName": "My Plugin",

301 "shortDescription": "Reusable skills and apps",

302 "longDescription": "Distribute skills and app integrations together.",

303 "developerName": "Your team",

304 "category": "Productivity",

305 "capabilities": ["Read", "Write"],

306 "websiteURL": "https://example.com",

307 "privacyPolicyURL": "https://example.com/privacy",

308 "termsOfServiceURL": "https://example.com/terms",

309 "defaultPrompt": [

310 "Use My Plugin to summarize new CRM notes.",

311 "Use My Plugin to triage new customer follow-ups."

312 ],

313 "brandColor": "#10A37F",

314 "composerIcon": "./assets/icon.png",

315 "logo": "./assets/logo.png",

316 "screenshots": ["./assets/screenshot-1.png"]

317 }

318}

319```

320 

321`.codex-plugin/plugin.json` is the required entry point. The other manifest

322fields are optional, but published plugins commonly use them.

323 

324### Manifest fields

325 

326Use the top-level fields to define package metadata and point to bundled

327components:

328 

329- `name`, `version`, and `description` identify the plugin.

330- `author`, `homepage`, `repository`, `license`, and `keywords` provide

331 publisher and discovery metadata.

332- `skills`, `mcpServers`, and `apps` point to bundled components relative to

333 the plugin root.

334- `interface` controls how install surfaces present the plugin.

335 

336Use the `interface` object for install-surface metadata:

337 

338- `displayName`, `shortDescription`, and `longDescription` control the title

339 and descriptive copy.

340- `developerName`, `category`, and `capabilities` add publisher and capability

341 metadata.

342- `websiteURL`, `privacyPolicyURL`, and `termsOfServiceURL` provide external

343 links.

344- `defaultPrompt`, `brandColor`, `composerIcon`, `logo`, and `screenshots`

345 control starter prompts and visual presentation.

346 

347### Path rules

348 

349- Keep manifest paths relative to the plugin root and start them with `./`.

350- Store visual assets such as `composerIcon`, `logo`, and `screenshots` under

351 `./assets/` when possible.

352- Use `skills` for bundled skill folders, `apps` for `.app.json`, and

353 `mcpServers` for `.mcp.json`.

354 

355### Publish official public plugins

356 

357Adding plugins to the official Plugin Directory is coming soon.

39As we release new models and API features, we recommend upgrading your integration to benefit from the latest improvements.

40Changing from one model to another is often not as simple as just updating the model name.

41 

42There might be changes to the API–for example, for the GPT-5.4 model, we added a new `phase` parameter to the assistant message that is important to include in your integration–but most importantly, model behavior can be different and require changes to your existing prompts.

43 

44When migrating to a new model, you should make sure to not only make the necessary code changes, but also evaluate the impact on your workflows.

45 

46## Leverage the OpenAI Docs skill

47 

48All the specifics about the new API features and model behavior are documented in our docs, in the [latest model](https://developers.openai.com/api/docs/guides/latest-model) and [prompt guidance](https://developers.openai.com/api/docs/guides/prompt-guidance) guides.

49 

50The OpenAI Docs skill also includes [specific guidance](https://github.com/openai/codex/blob/6323f0104d17d211029faab149231ba787f7da37/codex-rs/skills/src/assets/samples/openai-docs/references/upgrading-to-gpt-5p4.md) as reference, codifying how to upgrade to the latest model–currently [GPT-5.4](https://developers.openai.com/api/docs/models/gpt-5.4).

51 

52Codex now automatically comes with the OpenAI Docs skill, so make sure to mention it in your prompt to access all the latest documentation and guidance when building with the OpenAI API.

53 

54## Build a robust evals pipeline

55 

56Codex can automatically update your prompts based on the latest prompt guidance, but you should have a way to automate verifying your integration is working as expected.

57 

58Make sure to build an evals pipeline that you can run every time you make changes to your integration, to verify there is no regression in behavior.

59 

60This [cookbook guide](https://developers.openai.com/cookbook/examples/evaluation/building_resilient_prompts_using_an_evaluation_flywheel) covers in detail how to do this using our [Evals API](https://developers.openai.com/api/docs/guides/evals).

27 End with the files I should read next.

28 

29## Introduction

30 

31When you are new to a repo or dropped into an unfamiliar feature, Codex can help you get oriented before you start changing code. The goal is not just to get a high-level summary, but to map the request flow, understand which modules own what, and identify the next files worth reading.

32 

33## How to use

34 

35If you're new to a project, you can simply start by asking Codex to explain the whole codebase:

36 

37Explain this repo to me

38 

39If you need to contribute a new feature to an existing codebase, you can ask codex to explain a specific system area. The better you scope the request, the more concrete the explanation will be:

40 

411. Give Codex the relevant files, directories, or feature area you are trying to understand.

422. Ask it to trace the request flow and explain which modules own the business logic, transport, persistence, or UI.

433. Ask where validation, side effects, or state transitions happen before you edit anything.

444. End by asking which files you should read next and what the risky spots are.

45 

46A useful onboarding answer should leave you with a concrete map, not just a list of filenames. By the end, Codex should have explained the main flow, highlighted the risky parts, and pointed you to the next files or checks that matter before you start editing.

47 

48## Questions to ask next

49 

50Once Codex gives you a first pass, keep going until the explanation is specific enough that you would trust yourself to make the first edit. Good follow-up questions usually force it to call out assumptions, hidden dependencies, and the checks that matter after a change.

51 

52- Which module owns the actual business logic versus the transport or UI layer?

53- Where does validation happen, and what assumptions are enforced there?

54- What related files or background jobs are easy to miss if I change this flow?

55- Which tests or checks should I run after editing this area?

26## Starter prompt

27 

28Implement this UI in the current project using the screenshots and notes I provide as the source of truth.

29 Requirements:

30 - Reuse the existing design system components and tokens.

31- Translate the screenshots into this repo's utilities and component patterns instead of inventing a parallel system.

32 - Match spacing, layout, hierarchy, and responsive behavior closely.

33 - Respect the repo's routing, state, and data-fetch patterns.

34 - Make the page responsive on desktop and mobile.

35- If any screenshot detail is ambiguous, choose the simplest implementation that still matches the overall direction and note the assumption briefly.

36 Validation:

37- Compare the finished UI against the provided screenshots for both look and behavior.

38- Use $playwright-interactive to check that the UI matches the references and iterate as needed until it does.

39 

40## Introduction

41 

42When you have screenshots, a short design brief, or a few references for inspiration, Codex can turn those into responsive UI without ignoring the patterns already established in your project.

43 

44With the Playwright skill, Codex can open the app in a real browser, compare the implementation to your screenshots for different screen sizes, and iterate on layout or behavior until the result is closer to the target.

45 

46## Start from references

47 

48Give Codex the clearest references you have for the UI you want. A single screenshot can be enough for a narrow task, but the handoff gets better when you include multiple states such as desktop and mobile layouts, hover or selected states, and any empty or loading views that matter.

49 

50The references do not need to be perfect design deliverables. They just need to make the intended hierarchy, spacing, and direction concrete enough that Codex is not guessing.

51 

52## Be specific

53 

54The more specific you are about the expected interaction patterns and the style you want, the better the result will be.

55The model tends to default to high-frequency patterns and style so if it's not obvious from your references that you want something else, the UI might look generic.

56The more input you give, be it more reference inspiration or more specific instructions, the more you can expect to have a UI that stands out.

57 

58## Prepare the design system

59 

60Codex 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.

61 

62If you think it's necessary (i.e. if you're not using a standard stack), specify to Codex which primitives to reuse, where your tokens live, and what the repo considers canonical for buttons, inputs, cards, typography, and icons.

63 

64If you're starting from an existing codebase, it's very likely that Codex will understand on its own how to use your components and design system, but if starting from scratch, it's a good idea to be explicit.

65 

66Ask Codex to treat the screenshots as a visual target but to translate that target into the project's actual utilities, component wrappers, color system, typography scale, spacing tokens, routing, state management, and data-fetch patterns.

67 

68## Leverage Playwright

69 

70Playwright is a great tool to help Codex iterate on the UI. With it, Codex can open the app in a real browser, compare the implementation to the screenshots you provided, and iterate on layout or behavior.

71 

72It can resize the browser window to different screen sizes and check the layout at different breakpoints.

73 

74Make sure you have the Playwright interactive skill enabled in Codex. For more details, see the [skills documentation](https://developers.openai.com/codex/skills).

75 

76## Iterate

77 

78The first pass should already be directionally close to the screenshots. For complex layouts, interactions, or animation-heavy UI, expect a few rounds of adjustment.

79 

80Ask Codex to compare the implementation back to the screenshots, not just whether the page builds. When conflicts come up, it should prefer the repo's design-system tokens and only make minimal spacing or sizing adjustments needed to preserve the overall look of the design.

81 

82Use additional screenshots or short notes if they help clarify states that are not obvious from one image.

83 

84### Suggested follow-up prompt

85 

86[current implementation image] [reference image]

87This doesn't look right. Make sure to implement something that matches closely the reference:

88[if needed, specify what is different]

35- Preserve text as text and simple charts as native PowerPoint charts where practical.

36 - Add these slides: [describe new slides here]

37- Use the existing branding on new slides and new text (colors, fonts, layout, etc.)

38- Render the updated deck to slide images, review the output, and fix layout issues before delivery.

39- Run overflow and font-substitution checks before delivery, especially if the deck is dense.

40- Save reusable prompts or generation notes when you create a batch of related images.

41 Output:

42 - A copy of the slide deck with the changes applied

43 - notes on which slides were generated, rewritten, or left unchanged

44 

45## Introduction

46 

47You can use Codex to manipulate PowerPoint decks in a systematic way, using the Slides skill to create and edit decks with PptxGenJS, and using image generation to generate visuals for the slides.

48 

49Skills can be installed directly from the Codex app–see our [skills documentation](https://developers.openai.com/codex/skills) for more details.

50 

51You can create new decks from scratch, describing what you want, but the ideal workflow is to start from an existing deck–already set up with your branding guidelines–and ask Codex to edit it.

52 

53## Start from the source deck and references

54 

55If a deck already exists, ask Codex to inspect it before making changes.

56 

57The slides skill is opinionated here: match the source aspect ratio before you rebuild layout, and default to 16:9 only when the source material does not already define the deck size. If the references are screenshots or a PDF, ask Codex to render or inspect them first so it can compare slide geometry visually instead of guessing.

58 

59## Keep the deck editable

60 

61When building out new slides, ask Codex to keep the slides editable: when slides contain text, charts, or simple layout elements, those should stay PowerPoint-native when practical. Text should stay text. Simple bar, line, pie, and histogram visuals should stay native charts when possible. For diagrams or visuals that are too custom for native slide objects, Codex can generate or place SVG and image assets deliberately instead of rasterizing the whole slide.

62 

63For example, if you want to build a complex timeline with illustrations, instead of generating a whole image, ask Codex to generate each illustration separately (using a set style prompt as reference), place them on the slide, then link them using native lines. The text and dates should be text objects as well, and not included in the illustrations.

64 

65## Generate visuals intentionally

66 

67Image generation is most useful when the slides need a cover image, a concept illustration, or a lightweight diagram that would otherwise take manual design work. Ask Codex to define the visual direction first, then reuse that direction consistently across the whole deck.

68 

69When several slides need related visuals, have Codex save the prompts or generation notes it used. That makes the deck easier to extend later without starting over stylistically.

70 

71## Keep slide logic explicit

72 

73Deck automation works better when Codex treats each slide as its own decision. Some slides should preserve exact copy, some need a stronger headline and cleaner structure, and some should stay mostly untouched apart from asset cleanup or formatting fixes.

74 

75The slides skill also ships with bundled layout helpers. Ask Codex to copy those helpers into the working directory and reuse them instead of reimplementing spacing, text-sizing, and image-placement logic on every deck.

76 

77## Validation before delivery

78 

79Decks are easy to get almost right and still ship with clipped text, substituted fonts, or layout drift that only shows up after export. The slides skill includes scripts to render decks to per-slide PNGs, build a quick montage for review, detect overflow beyond the slide canvas, and report missing or substituted fonts.

80 

81Ask Codex to use those checks before it hands back the final deck, especially when slides are dense or margins are tight.

82 

83## Example ideas

84 

85Here are some ideas you could try with this use case:

86 

87### New deck from scratch

88 

89You can create new slide decks from scratch, describing what you want slide by slide and the overall vibe.

90If you have assets like logos or images, you can copy them in the same folder so that Codex can easily access them.

91 

92Create a new slide deck with the following slides:

93- Slide 1: Title slide with the company logo (logo.png) and the title of the presentation

94- Slide 2: Agenda slide with the key points of the presentation

95- Slide 3: [TITLE] [TAGLINE] [DESCRIPTION]

96- ...

97- Slide N: Conclusion slide with the key takeaways

98- Slide N+1: Q&A slide with my picture (my-picture.png)

99 

100### Deck template update

101 

102You can update a deck template on a regular basis (weekly, monthly, quarterly, etc.) with new content.

103If you're doing this frequently, create a file like `guidelines.md` to define the content and structure of the deck and how it should be updated.

104 

105Combine it with other skills to fetch information from your preferred data

106 sources.

107 

108For example, if you need to give quarterly updates to your stakeholders, you can update the deck template with new numbers and insights.

109 

110Update the deck template, pulling content from [integration 1] and [integration 2].

111Make sure to follow guidelines defined in guidelines.md.

112 

113### Adjust existing deck

114 

115If you built a deck but want to adjust it to fix spacing, misaligned text, or other layout issues, you can ask Codex to fix it.

116 

117Adjust the deck to make sure the following layout rules are followed:

118- Spacing should be consistent when there are multiple items on the same slide displayed in a row or grid.

119- When there are multiple items on the same slide displayed in a row or grid, the items are aligned horizontally or vertically depending on the content.

120- All text boxes should be aligned left, except when they are below an illustration

121- All titles should use the font [font name] and size [size]

122- All captions should be in [color]

123- ....

30## How to use

31 

32Start by adding Codex code review to your GitHub organization or repository. See [Use Codex in GitHub](https://developers.openai.com/codex/integrations/github) for more details.

33 

34You can set up Codex to automatically review every pull request, or you can request a review with `@codex review` in a pull request comment.

35 

36If Codex flags a regression or potential issue, you can ask it to fix it by commenting on the pull request with a follow-up prompt like `@codex fix it`.

37 

38This will start a new cloud task that will fix the issue and update the pull request.

39 

40## Define additional guidance

41 

42To customize what Codex reviews, add or update a top-level `AGENTS.md` with a section like this:

43 

44```md

45## Review guidelines

46 

47- Flag typos and grammar issues as P0 issues.

48- Flag potential missing documentation as P1 issues.

49- Flag missing tests as P1 issues.

50 ...

51```

52 

53Codex applies guidance from the closest `AGENTS.md` to each changed file. You can place more specific instructions deeper in the tree when particular packages need extra scrutiny.

15## Best for

16 

17- Problems where each iteration can be scored, but the best result usually takes many passes

18- Tasks with visual or subjective outputs that need both deterministic checks and an LLM-as-a-judge score

19- Long-running Codex sessions where you want progress tracked clearly instead of relying on context

20 

21## Starter prompt

22 

23I have a difficult task in this workspace and I want you to run it as an eval-driven improvement loop.

24 Before changing anything:

25 - Read `AGENTS.md`.

26 - Find the script or command that scores the current output.

27 Iteration loop:

28 - Make one focused improvement at a time.

29 - Re-run the eval command after each meaningful change.

30 - Log the scores and what changed.

31- Inspect generated artifacts directly. If the output is visual, use `view\_image`.

32 - Keep going until both the overall score and the LLM average are above 90%.

33 Constraints:

34 - Do not stop at the first acceptable result.

35- Do not revert to an earlier version unless the new result is clearly worse in scores or artifacts.

36- If the eval improves but is still below target, explain the bottleneck and continue.

37 Output:

38 - current best scores

39 - log of major iterations

40 - remaining risks or weak spots

41 

42## Introduction

43 

44Some tasks are easy to verify in one shot: the build passes, the tests go green, and you are done. But there are some optimization problems that are difficult to solve, and need many iterations with a tight evaluation loop. To know which direction to go in, Codex needs to inspect the current output, score it, decide the next change, and repeat until the result is actually good.

45 

46This type of use case pairs well with a custom UI that lets you inspect progress visually, by having Codex log the outputs and generated artifacts for each iteration.

47You can watch Codex continue working in the app while the target artifact, model output, or generated asset keeps improving.

48The key is to give Codex the necessary scripts to generate the evaluation metrics and the artifacts to inspect.

49 

50## Start with evals

51 

52Before the task begins, define how success will be measured. The best setup usually combines:

53 

54- **Deterministic checks:** things the scripts can score directly, such as constraint violations or deterministic metrics computed with code

55- **LLM-as-a-judge checks:** rubric-based scores for qualities that are harder to encode exactly, such as resemblance, readability, usefulness, or overall quality - this can rely on text or image outputs

56 

57If the subjective part matters, give Codex a script that can call a model for example using the [Responses API](https://developers.openai.com/api/reference/resources/responses/methods/create) and return structured scores. The point is not to replace deterministic checks, it's to supplement them with a consistent judge for the part humans would otherwise assess by eye.

58 

59The loop works best when the eval output is machine-readable, saved after every run, and easy to compare over time.

60 

61**Tip**: Ask Codex to generate the evaluation script for you, describing the

62 checks you want to run.

63 

64## Give Codex a stopping rule

65 

66Hard tasks often drift because the prompt says “keep improving” without saying when to stop. Make the stopping rule explicit.

67 

68A practical pattern is:

69 

701. Set a target for the overall score.

712. Set a separate target for the LLM-judge average.

723. Tell Codex to continue until both are above the threshold, not just one.

73 

74For example, if the goal is a high-quality artifact, ask Codex to keep going until both the overall score and the LLM average are above 90%. That makes the task legible: Codex can tell whether it is still below target, where the gap is, and whether the latest change helped.

75 

76## Keep a running log of the loop

77 

78Long-running work is much more reliable when Codex keeps notes about the loop instead of trying to remember everything from the thread.

79 

80That running log should record:

81 

82- the current best scores

83- what changed on the last iteration

84- what the eval said got better or worse

85- what Codex plans to try next

86 

87This is especially important when the task runs for a long time. The log becomes the handoff point for the next session and the self-evaluation record for the current one.

88 

89## Inspect the artifact, not just the logs

90 

91For some difficult tasks, the code diff and metric output are not enough. Codex should look at the artifact it produced.

92 

93If the output is visual, such as a generated image, layout, or rendered state, let Codex inspect that artifact directly, for example when the output lives on disk as an image and compare the current result to the prior best result or to the intended rubric.

94 

95This makes the loop stronger:

96 

97- the eval script reports the score

98- the artifact shows what the score missed

99- the next change is grounded in both

100 

101That combination is much more effective than changing code blindly between runs.

102 

103## Make every iteration explicit

104 

105Ask Codex to follow the same loop every time:

106 

1071. Run the evals on the current baseline.

1082. Identify the biggest failure mode from the scores and artifacts.

1093. Make one focused change that addresses that bottleneck.

1104. Re-run the evals.

1115. Log the new scores and whether the change helped.

1126. Continue until the thresholds are met.

113 

114This discipline matters. If each iteration changes too many things at once, Codex cannot tell which idea improved the score. If it skips logging, the session becomes hard to trust and hard to resume.
