Codex
Codex is an independent agent on PATH (codex), sharing this working tree and
already authenticated. It is a second opinion, not ground truth: verify what it
reports, own what it changes.
If codex is not installed
When codex is missing from PATH, offer to install it — ask the user for
approval first, never install on your own initiative. On yes, follow the
current instructions at https://developers.openai.com/codex/cli. First-run
authentication is interactive — hand that step to the user. Verify with
codex --version before proceeding.
