# Code review — pre-commit validation

**Apply on every pull request review.** These checks are blocking. Do not approve a PR until all pass or the author has addressed failures.

## Review checklist (run every time)

| # | Gate | Command | On failure |
|---|------|---------|------------|
| 1 | Commit messages | `printf '%s' "$MSG" \| pnpm exec commitlint` per commit | Blocking comment + suggested fix |
| 2 | Workspace | `test -f node_modules/.modules.yaml` | Request `pnpm install` |
| 3 | Lint | `pnpm run lint` | Blocking; suggest `pnpm run lint:fix` |
| 4 | Format | `pnpm run fmt:check` | Blocking; suggest `pnpm run fmt` |

Run all commands from the repo root after `pnpm install`.

## Commit messages (commitlint)

Every commit must follow [Conventional Commits](https://www.conventionalcommits.org/) per `commitlint.config.ts` (`@commitlint/config-conventional`).

```
type(optional-scope): imperative subject

Optional body explaining why.
```

- Types: `feat`, `fix`, `docs`, `style`, `refactor`, `perf`, `test`, `chore`, `ci`, `build`
- Subject: lowercase, imperative mood, no trailing period
- Blank line between title and body when a body is present

## Auto-fix loop

```bash
pnpm run lint:fix
pnpm run fmt
pnpm run lint
pnpm run fmt:check
```

## Common commitlint failures

| Error | Fix |
|-------|-----|
| `type-empty` / `subject-empty` | Use `type: subject` format |
| `type-enum` | Use an allowed conventional type |
| `subject-case` | Keep subject lowercase |
| `subject-full-stop` | Remove trailing `.` from subject |
