Codex Advisor
Get a focused second opinion from GPT 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-5.6-sol` at medium reasoning effort. Inside Codex that may be the model already doing the work, so set `CODEX_ADVISOR_MODEL` to a different one.
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.
