Get a second opinion or independent review from Codex (OpenAI) via the local Codex CLI. Use when the user wants Codex to review a design memo, PR, diff, or decision, or to cross-check an approach from another model. Also trigger on "Codexに聞いて", "Codexと相談", "Codexにレビュー", "Codexの意見", "別のモデルで確認".
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
## Purpose
Delegate a focused question or review to **Codex** (OpenAI's CLI) and relay
its answer back to the user as an independent, attributed second opinion.
This skill does not replace your own judgment — it gathers Codex's view so the
user can compare it against yours (and against other reviewers such as
Antigravity).
## How Codex is invoked
The repository ships a project-local Codex config (`.codex/config.toml`) and a
wrapper script. Always call Codex through the script so the project config and
working directory are correct:
```bash
npm run codex:exec -- "<prompt>"
```
This runs `codex exec` non-interactively (`CODEX_HOME=.codex`, `-C <repo root>`)
and prints Codex's answer to stdout. Codex runs in the repo, so it can read
files itself — reference paths in the prompt instead of pasting large files.
## Steps
1. **Frame the prompt.** Turn the user's request into a single self-contained
prompt for Codex. Include:
- the role ("You are a senior reviewer of River Review …"),
- the file paths Codex should read (e.g. `docs/development/1255-…md`,
`runners/core/review-runner.mjs`),
- the specific questions to answer, numbered,
…Read the whole file at its exact version.
How to install
mdr add s977043/river-review/ask-codex@sha256:e816d075eeaacc52The line at the top of this page pins the label git:20260724.d54eafd, 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.
