PR Review Skill

Comprehensive pull request review that analyzes code quality, architecture, test coverage, and identifies scope creep (unrelated changes mixed into the PR).

Activation Triggers

"review pr 123", "check pr 123", "look at pr 123"
"review the pr", "what do you think about this pr"
"review draft pr", "check the open pr"
"comment on issue 42", "look at issue 42", "review issue 42"

Workflow

1. Fetch PR metadata + discussion history + merge status
1.5. Ask review mode: Full (default) or Quick
--- Full path ---
2. Setup worktree, launch subagent for deep analysis (read files, validate, architecture, scope creep, cleanup)
3. Present condensed findings from subagent, ask to proceed
4. Resolve open questions (if any)
5. Draft review comment
--- Quick path ---
Q1. Read diff inline, summarize what/why/size
Q2. Flag obvious issues from diff
Q3. Draft review comment

Phase 0: Detect PR vs Issue

Determine if the target is a PR or an issue. If a URL is provided, check if it contains /pull/ or /issues/. If just a number, detect type:

gh pr view <number> --json number 2>/dev/null && echo "PR" || echo "ISSUE"

PR → proceed with full PR review workflow (Phase 1 onwards)
Issue → use the Issue Comment Flow below, skip all PR-specific phases

Issue Comment Flow

For issues, skip worktree/diff/architecture analysis. Focus on understanding the issue and drafting a helpful comment.
