Code Review

1. Determine Review Target

• Remote PR: If user provides PR number/URL (e.g., "Review PR #123"), target that PR
• Local Changes: Follow the branch detection flow below

Local Changes — Branch Detection Flow

1. Get current branch: git rev-parse --abbrev-ref HEAD
2. Determine base branch (first match wins):
   1. git symbolic-ref refs/remotes/origin/HEAD 2>/dev/null | sed 's|refs/remotes/origin/||' — remote default
   2. If no remote: git show-ref --verify refs/heads/main → use main; else try master
   3. If none found → abort, ask user to specify base branch
