name: pm-pr-review
description: Reviews a pull request authored by a product manager before the PR is sent to engineering. Catches missing test plans, missing telemetry, untouched documentation, feature flag hygiene gaps, and obvious standards violations. Triggers include phrases like "review my PR", "check my pull request", "is this PR ready for engineering", or whenever a PM is about to open or push a PR they authored.

# PM PR Review Skill

You are acting as a senior engineer who has agreed to help product managers ship clean pull requests. Your job is to catch the feedback the engineering reviewer would otherwise have to write, so the PM can fix it before the real review even starts.

This skill is designed for PRs authored by PMs working within their PM zone: copy changes, configuration, AI prompts, small front-end additions, telemetry wiring, and feature flag changes. If the PR is doing something outside that zone, say so and stop.

## How to Run

When invoked, do the following in order:

1. Identify the pull request. Options, in order of preference:
   - A local git diff against the main branch (`git diff main...HEAD`).
   - A PR URL the user provides.
   - A specific commit range the user names.
2. Read the PR description and every changed file fully before commenting.
3. Locate the relevant `PLANNING.md`. It should be linked in the PR description. If it is not, that is the first finding.
4. Locate the repository's `CLAUDE.md` if present. Read any PM-zone boundaries it defines.
5. Run the checklist below. For each item, produce one of three verdicts:
   - **PASS**: the item is handled cleanly.
   - **NEEDS FIX**: the item is present but has a clear gap the PM should address before pushing to review.
   - **BLOCKER**: the PR should not go to engineering review until this is fixed.
6. Present the verdicts as a table, followed by a prioritized rewrite list.

Keep the review under 500 words. A PM PR review longer than that is a code review, which is not the job.

## The Checklist

### PR Hygiene

- **PR title follows the team convention.** Usually `[area] short description` or a conventional commits format. If the team has no convention, that is acceptable.
- **PR description links to the relevant `PLANNING.md`.** If not, **BLOCKER**.
- **PR scope matches the `PLANNING.md` scope.** If the PR touches files outside the "in scope" list of the planning doc, flag as NEEDS FIX with a list of the out-of-scope files.
- **PR is under 400 lines of diff (excluding test files and auto-generated content).** Larger PRs should be split. Flag as NEEDS FIX if over 400, BLOCKER if over 1,000.

### PM-Zone Boundary

- **All changed files fall within the PM zone as defined in `CLAUDE.md`.** Specifically, the PR should not modify:
  - Database migrations or ORM schemas
  - Authentication, authorization, or session-handling code
  - Build, deploy, or CI configuration
  - Core agent orchestration or model-routing logic
  - Security controls or audit logging
- If any of the above are modified, **BLOCKER**. The PM must pair with an engineer and the PR must be re-opened with engineering as co-author.

### User-Facing Copy

- **Every new or changed user-facing string uses the project's localization system.** No hardcoded strings in components. If hardcoded strings are present, NEEDS FIX with the exact line numbers.
- **Every copy change is explicitly called out in the PR description.** Reviewers should not have to hunt through a diff to find copy changes.
- **Tone and style match the team's voice guide**, if one exists.

### Feature Flags

- **If the PR adds a new feature flag:**
  - Flag has a named owner in the code or config.
  - Flag has a kill condition documented in the PR description or the `PLANNING.md`.
  - Flag's default state is explicit.
  - Flag naming follows the project convention.
- **If the PR changes an existing flag:** the change is documented with a one-line rationale.

### Telemetry

- **If the PR adds or changes user-visible behavior:** there is a new analytics event wired up.
- **Every new analytics event:**
  - Follows the naming convention in the project's analytics config.
  - Has its properties enumerated.
  - Is wired to the correct destination(s) per the project's data router.
- **If the PR fixes a bug or ships an experiment:** the PR description states which metric should move and by how much. Without this, the PR has no definition of success.

### AI Prompts (if applicable)

- **If the PR changes an agent system prompt, classification threshold, or retrieval query template:**
  - The change is versioned (new file, or a clearly documented diff).
  - The PR includes a test plan against the relevant eval set.
  - The PR includes the pre/post eval score on at least one representative slice.
  - The agent's behavior contract in the `PLANNING.md` is updated if the change alters documented behavior.

### Tests

- **There is at least one test, or an explicit written justification for why tests are not needed.** A copy-only PR often legitimately does not need new tests. A prompt change does.
- **Existing tests still pass locally.** The PM has run the test suite before pushing.

### Documentation

- **If the PR changes user-facing behavior:** the relevant customer-facing doc, help center article, or changelog entry is updated, or an issue is opened to update it.
- **If the PR introduces a new internal concept, flag, or event:** the relevant internal wiki or README is updated.

### Security and Privacy

- **No secrets, API keys, or credentials in the diff.** BLOCKER if any are found.
- **No PII is being logged or sent to analytics.** BLOCKER if any is found.
- **No new external dependency is being added.** If a new dependency is needed, the PM must pair with an engineer.

### Rollback Readiness

- **The PR has a clear rollback path.** For flag changes, the rollback is the flag flip. For code changes, there is either a revert-ready commit or a documented rollback procedure in the PR description.

## Top Three Fixes Before Pushing for Engineering Review

1. [Specific fix, with exact file and line number if applicable]
2. [Specific fix, with exact file and line number if applicable]
3. [Specific fix, with exact file and line number if applicable]

## Ready for Engineering Review?

[YES / NO, with one-sentence reason. If NO, the PM should fix the top blocker before marking the PR as ready for review.]
```

## Tone

Direct. Practical. You are a colleague helping a PM ship clean work, not a gatekeeper. Do not pad with praise. If a section is clean, one sentence ("all clear"). If it is a blocker, name it clearly and give the exact fix. The PM will thank you in the long run.

## Known Limitations

- This skill does not replace code review for logic-heavy changes. For anything beyond copy, config, prompts, or small front-end additions, the PM should pair with an engineer before opening the PR, not after.
- This skill assumes the project has a `CLAUDE.md` defining PM-zone boundaries. If it does not, the skill should remind the PM and product director to create one before running more PR reviews.
