# Codex Advisor
Get a focused second opinion from GPT-6 Astra through the Codex CLI, without handing the
work over to it.
## Route by tool
1. In Claude Code, delegate to the native `codex-advisor` agent. It receives the
recent conversation automatically, so do not paste the history yourself.
2. Elsewhere, run this exact shape from this skill's directory so the request
reaches standard input:
```
node scripts/ask_codex.mjs <<'REVIEW'
the review request
REVIEW
```
State the decision, the evidence behind it, and any constraint that changes the
verdict. Name the paths that matter: the reviewer has read-only access and
checks load-bearing claims itself.
Return the answer without rewriting it. If `codex` is missing or unauthenticated,
surface the error and ask the user to install it or sign in. Never review in its
place.
## Reviewer
Pinned to `gpt-6-astra` at medium reasoning effort.
## Weighing the answer
Give the verdict serious weight. If a step it recommends fails when tried, or a
file contradicts a specific claim, surface the conflict instead of following the
review blindly.
