Review PR
Overview
Use this skill to review your own pull requests or to get a pre-review of your local changes before opening a PR. It helps you fetch the details, check out the PR locally, and analyze the diff against project standards.
Checking out the PR locally first ensures you can apply and test changes directly during the review.
Workflow
1. Gather Context
Determine if you are reviewing an open PR or local changes.
If reviewing an existing PR:
- Run
gh pr checkout <pr-number> FIRST to ensure you have the changes locally.
- Run
gh pr view --json title,body,author,headRefName,baseRefName to understand the intent.
- Run
gh pr diff or git diff to review the actual code changes.
If reviewing local changes (Pre-PR Review):
- Run
git status to see what is being worked on.
- Run
git diff HEAD to get the full diff of all tracked changes (or git diff --staged if reviewing a specific staged commit).
- Run
git log -n 1 to understand the context if a commit has already been made locally.
For both:
- Cross-reference the changes with project conventions in
CONTRIBUTING.md and doc/howwewritego.md if necessary.
2. Analyze the Changes
Check the diff rigorously against the project's standards defined in doc/howwewritego.md and CONTRIBUTING.md:
General & Go Idioms:
- "Clear is better than clever." "Write simple, boring, readable code."
- Naming: Name length corresponds to scope size. Use singular form for package/folder names (e.g.,
image/, not images/).
- Comments: Do not explain standard Go concepts or comment on obvious logic.
- Vertical Density: Use line breaks only to signal a shift in logic. Avoid unnecessary vertical padding. Group related lines tightly.
- Idiomatic Go: Flag patterns that conflict with
doc/styleguide/go-code-review-comments.md (e.g., use errors.Is/errors.As, early returns).
Project-Specific Rules:
internal/command: Ensure command.Run is used for execution.internal/testhelper: Ensure existing utilities are used before creating new test tools.internal/yaml: Ensure this package is used instead of gopkg.in/yaml.v3.
Testing & Documentation:
- Testing Quality: Ensure tests are added or updated for new logic, following
doc/styleguide/go-test-comments.md.
- Markdown: Ensure Markdown changes follow the Google Markdown Style Guide (
doc/styleguide/markdown-style-guide.md).
- Commits and PR Body: If reviewing an existing PR, evaluate the PR body (which will become the commit message) using the conventions from the
/commit-message skill. It must follow CONTRIBUTING.md, be written in complete sentences, and use the imperative mood.
CRITICAL RULE: NEVER automatically push commits to GitHub. Always create commits or apply changes locally. ALWAYS use the ask_user tool at the end to allow the user to select which specific changes they want applied locally.
Output Format
Present the findings from the analysis clearly. ONLY include findings that suggest or require specific changes. Do NOT include complimentary comments or general positive feedback.
Overall Assessment: [Brief summary of the PR or local change quality]
Findings:
(Indicate the file and line number for each change suggested)
1. **File/Line:** [Description of actionable change]
2. **File/Line:** [Description of actionable change]
After presenting the findings, use the ask_user tool. Provide a multiple-choice question (type: 'choice', multiSelect: true) listing each of the numbered findings as an option. Ask the user: "Which of these changes would you like me to apply locally?"
