Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| codexA | Execute a Codex task and block until completion. Use read-only sandbox for reviews/analysis, full-access for code modifications. full-access mode creates a git worktree for isolation. Returns the final result, session_id (for resume), and git diff stats. |
| codex_dispatchA | Dispatch a long-running Codex task to background and return immediately. The task runs in a persistent tmux session that survives disconnects. Use codex_status to check progress and codex_cancel to stop. |
| codex_statusA | Check task status. Pass task_id for single task detail (with progress events if running, or result/diff if completed). Omit task_id to list all tasks. |
| codex_cancelA | Cancel a running Codex task by killing its tmux session. |
