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".
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 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 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-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.

How to install
mdr add fcakyon/claude-codex-settings/codex-advisor@sha256:3c4e8712cfea4e4aThe line at the top of this page pins the label git:20260924.e7bd635, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
