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
In Claude Code, delegate to the native codex-advisor agent. It receives the
recent conversation automatically, so do not paste the history yourself.
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.
