# Runtime: codex

The Codex CLI (`@botgumi/codex-runtime`, stub).

- Instructions: Codex reads `AGENTS.md` from the repo root.
- Roles: Codex has no agent files, so the runtime puts the role file's body before the brief in the prompt.
- Workers and reviewers: `codex exec --model <model> "<role file body + brief>"`.
