1. Detect review mode (PR or local).
2. Read changes to understand intent.
3. Check for style guide violations and readability issues.
4. Number each issue sequentially.
5. Format feedback according to the review mode (GitHub comment or markdown list).
6. In PR mode, use `mcp__github__create_pending_pull_request_review`, `mcp__github__get_pull_request_diff`, `mcp__github__add_pull_request_review_comment_to_pending_review`, and `mcp__github__submit_pending_pull_request_review`.
7. Ensure all issues are worth addressing.
8. Verify format and numbering.
