Review Pr

PR Review Skill

Review the pull request at $ARGUMENTS.

Workflow

1. Fetch PR details using mcp__github__pull_request_read with methods get and get_diff in parallel to understand the full change.
2. Explore relevant existing code to understand patterns, conventions, and context around the changed files. Use the Explore agent or read files directly.
3. Analyze the diff thoroughly for:
   • Code quality, readability, and style consistency with the existing codebase
   • Bugs, potential NPEs, edge cases, and error handling issues
   • Code duplication or missed reuse opportunities
   • Test coverage and test style consistency
   • Security concerns
   • Naming, formatting, and minor issues (trailing newlines, etc.)
4. Create a pending review using mcp__github__pull_request_review_write with method create (no event parameter — this creates a pending review).
5. Add inline comments on specific diff lines using mcp__github__add_comment_to_pending_review. Place each comment on the most relevant line(s) of the diff. Use startLine/line for multi-line comments where appropriate.
6. Ask the user how they want to submit the review. Present options:
   • COMMENT — neutral feedback
   • APPROVE — approve the PR
   • REQUEST_CHANGES — request changes
   • Keep pending — leave it as pending for further editing in GitHub UI

Important rules

• NEVER submit the review automatically. ALWAYS ask the user which event to use.
• Prefer inline comments on specific lines over a single summary comment.
• Keep comments concise and actionable. Include code suggestions where helpful.
• Match the tone to the severity: bugs and NPEs deserve strong language, style nits can be gentle.
