Cross-provider adversarial review of a finalized plan, spec, design doc, ADR, or code diff using OpenAI Codex (GPT-6 Sol), paired in round 1 with a blind Opus reviewer. AUTO-TRIGGER at plan gates — invoke immediately after any of: (1) a plan or spec is finalized, (2) an ADR draft is completed. AUTO-TRIGGER for code: after implementing a Codex-reviewed plan, run diff mode on the branch range before opening the PR — a reviewed plan is NOT a reviewed diff. Also invoke on request —…
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 Plan Review Send a finalized plan/spec/design/ADR to OpenAI Codex (`gpt-6-sol`, medium effort, read-only sandbox) for adversarial review, with a blind Opus reviewer running the same prompt in parallel for round 1. The script handles mechanics; you handle judgment. Script path (resolve via this skill's base directory): `scripts/codex-review.mjs`, run with `node`. **The one non-negotiable prompt rule:** the reviewer must never see your self-assessment. The script builds prompts from the file path only — never paste plan content, your confidence, or "tests pass" claims into any codex invocation. (Research: implementer framing degrades Codex review thoroughness 3–4×.) ## Flow 1. **Announce:** "Running Codex plan review (Sol, medium effort) plus a blind Opus reviewer (medium) — round 1." `gpt-6-sol` needs Codex CLI 0.158+ on a ChatGPT login (older clients do not list it); if a round returns `verdict:"error"` and its `errorDetail` says the model is unavailable, close that chain (`note --chain <id> --unique 0 --outcome aborted --comment "model unavailable"`; an aborted chain does not block a new one), then rerun with `--model <available model>` and say which. If `codex` is… …

How to install
mdr add jasonm4130/claude-skills/codex-plan-review@sha256:700d4a783d056d49The line at the top of this page pins the label git:20260929.0b2c937, 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.
