Codex Advisor

\n

Get a focused second opinion from GPT through the Codex CLI, without handing the\nwork over to it.

\n

Route by tool

\n
    \n

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

    \n
    2. \n

  2. Elsewhere, run this exact shape from this skill's directory so the request\nreaches standard input:

    \n
    node scripts/ask_codex.mjs <<'REVIEW'\nthe review request\nREVIEW\n
    \n
    3. \n
\n

State the decision, the evidence behind it, and any constraint that changes the\nverdict. Name the paths that matter: the reviewer has read-only access and\nchecks load-bearing claims itself.

\n

Return the answer without rewriting it. If codex is missing or unauthenticated,\nsurface the error and ask the user to install it or sign in. Never review in its\nplace.

\n

Reviewer

\n

Pinned to gpt-5.6-sol at medium reasoning effort. Inside Codex that may be the\nmodel already doing the work, so set CODEX_ADVISOR_MODEL to a different one.

\n

Weighing the answer

\n

Give the verdict serious weight. If a step it recommends fails when tried, or a\nfile contradicts a specific claim, surface the conflict instead of following the\nreview blindly.
