Codex Advisor
SkillAI & modelsThis skill gives your AI a way to get a second opinion from GPT on its plans and work. Once added, your AI can have another model review an approach before you commit to it, or take a fresh look when earlier attempts keep failing.
Available today. Use it from your connected AI after setup.
No other account needed.
Add the skill, then ask your AI for a 'GPT second opinion' or a cross-model review when you want another view on a plan or a problem that keeps failing.
Then ask your AI: use the Codex Advisor skill
What your AI can do with it
- Get a GPT second opinion on a plan or approach
- Have another model review work before you commit to it
- Request a cross-model review for a second perspective
- Get a fresh view after repeated failed attempts
- Ask for a second opinion by name whenever you want one
What this skill tells your AI
The instructions your AI receives, as published by fcakyon/claude-codex-settings in plugins/codex-advisor/skills/codex-advisor/SKILL.md and read by ahel’s review.
Get a focused second opinion from GPT through the Codex CLI, without handing the work over to it.
Route by tool
-
In Claude Code, delegate to the native
codex-advisoragent. 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-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.
