description: This skill should be used when the user asks for a "GPT second opinion", wants a "cross-model review", needs to "check a plan before committing", wants another view after repeated failures, or explicitly invokes "codex-advisor".

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.
