Fix Elixir/Phoenix code until Codex CLI review comes back clean — bounded review, fix, verify loop before opening a PR. Use when codex is installed and you want an external cross-model critic on your changes before pushing.
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 Loop (fix until clean) Critic→Refiner loop with the Codex CLI as external critic: review → fix approved findings → verify → re-review, until codex is clean or rounds run out. Codex reviews; Claude fixes. Complements `/phx:review` (Claude panel) — run either or both before a PR. ## Usage ``` /phx:codex-loop # diff vs default branch, interactive /phx:codex-loop --uncommitted # staged + unstaged + untracked /phx:codex-loop --base develop # explicit base branch /phx:codex-loop --auto # auto-approve P0/P1/P2, skip P3 /phx:codex-loop --max-rounds 2 # default 3 ``` ## Iron Laws 1. **BOUNDED rounds — never exceed --max-rounds (default 3)** — each round costs codex quota; report remaining findings instead of looping on 2. **Verify BEFORE re-review** — `mix compile --warnings-as-errors` + tests must pass before burning a codex round on broken code 3. **NEVER commit or push** — leave git to the user 4. **Codex findings get Iron Law scrutiny** — decline suggestions that violate an Iron Law, with explanation in the round report 5. **Skipped findings are reported, never dropped** — every finding ends as …

How to install
mdr add oliver-kriska/claude-elixir-phoenix/codex-loop@sha256:de8b867d9fe08899The line at the top of this page pins the label git:20261016.57d6f30, 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.
