240These options apply to the base `codex` command and propagate to each subcommand unless a section below specifies otherwise.

241When you run a subcommand, place global flags after it (for example, `codex exec --oss ...`) so Codex applies them as intended.

514## Command details

515 

516### `codex` (interactive)

517 

518Running `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`.

519 

520Use `--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. See [Codex CLI features](https://developers.openai.com/codex/cli/features#connect-the-tui-to-a-remote-app-server) for setup examples and authentication guidance.

521 

522### `codex app-server`

523 

524Launch the Codex app server locally. This is primarily for development and debugging and may change without notice.

525 

526| Key | Type / Values | Details |

527| --- | --- | --- |

532| `--ws-max-clock-skew-seconds` | `number` | Clock skew allowance when validating signed bearer token `exp` and `nbf` claims. Requires `--ws-auth signed-bearer-token`. |

533| `--ws-shared-secret-file` | `absolute path` | File containing the HMAC shared secret used to validate signed JWT bearer tokens. Required with `--ws-auth signed-bearer-token`. |

534| `--ws-token-file` | `absolute path` | File containing the shared capability token. Required with `--ws-auth capability-token`. |

The server accepts `ws://` listen URLs; use TLS termination or a secure proxy when clients connect with `wss://`. If you generate schemas for client bindings, add `--experimental` to include gated fields and methods.
