PR Review Skill

Review GitHub pull requests systematically for the mimo2codex project.

When to use

Trigger this skill when:

• User shares a GitHub PR URL (e.g., https://github.com/7as0nch/mimo2codex/pull/XX)
• User asks "看看这个PR" / "review this PR" / "值得合并吗"
• User wants to assess merge-worthiness of a contribution
• User asks to check a PR for issues before merging

Workflow

1. Fetch PR Information

# Get PR details
gh pr view <PR_NUMBER> --json title,body,state,author,additions,deletions,changedFiles,mergeable,reviewDecision

# Get PR diff
gh pr diff <PR_NUMBER>

# Get PR comments/reviews
gh api repos/7as0nch/mimo2codex/pulls/<PR_NUMBER>/comments

2. Analyze Code Changes

Review the diff for:

• Code quality: naming, structure, error handling
• Security: credentials, injection, unsafe operations
• Compatibility: breaking changes, API changes
• Tests: adequate coverage, test quality
• Documentation: README updates, comments

3. Assess Merge-Worthiness

Check:

• Does it solve a real problem?
• Is the approach sound?
• Are there simpler alternatives?
• Will it break existing functionality?
• Does it follow project conventions?

4. Provide Feedback Structure

## PR #XX: [Title]

**Author**: @username
**Status**: [Open/Merged/Closed]
**Changes**: +XX / -XX lines across XX files

### Summary
[One-paragraph overview of what this PR does]

### Assessment
- **Merge-worthiness**: ✅ Recommended / ⚠️ Needs changes / ❌ Not recommended
- **Quality**: [High/Medium/Low]
- **Risk**: [Low/Medium/High]

### Strengths
- [Positive aspects]

### Issues Found
- [List any issues, concerns, or suggestions]

### Recommendation
[Clear recommendation with reasoning]

5. If Merging

When the user decides to merge:

1. Preserve author's commit history
2. Create a new branch if needed
3. Merge to main with proper commit message
4. Verify the merge didn't break anything

Example Usage

User: https://github.com/7as0nch/mimo2codex/pull/68 ，你看一下这个pr，值得合并不，有问题没，有的话怎么回复作者

Agent workflow:
1. gh pr view 68 --json title,body,state,author,additions,deletions,changedFiles,mergeable
2. gh pr diff 68
3. Analyze the changes
4. Provide structured assessment
5. If user wants to merge: preserve author commits, merge to main
