 name: advise
 description: Get a second opinion from two independent advisors at once, Codex (read-only via `codex exec`) and a Claude advisor subagent, then merge their verdicts. Use it only when the user asks for it, for example "get a second opinion", "ask codex and fable", or "multi-advisor", or when the user's own configuration asks for it, such as a subagent definition that runs it as a QA check before reporting back. A run sends the brief and the repository files Codex reads to OpenAI through the user's Codex login, so never start it on your own initiative, however large or risky the task looks.

 name: exec
 description: Delegate implementation work to OpenAI Codex running headless via `codex exec`. Claude scopes the task and verifies the result; codex writes all the code. Use this whenever the user says "have codex do this", "delegate this to codex", "get codex to implement/fix/refactor X", "run this through codex", mentions codex headless or `codex exec`, or asks for work to be handed to another agent while Claude supervises. Also use it when the user wants a large implementation done without spending Claude's context on writing the code. Do NOT use it for questions you can answer directly, one-line edits, or when the user asked you specifically to make the change yourself.
