Do Review

Reviewer-side merge-risk assessment for GitHub pull requests, branch diffs, and local working-tree diffs. Treat the change as a proposal with an intended outcome, not as a pile of files. Prioritize goal achievement, correctness, security, data safety, contract compatibility, test evidence, and existing review state.

When To Use

Trigger on phrases and contexts like:

• "review PR #123", "review this PR", "review github.com/owner/repo/pull/N"
• "is this safe to merge?", "merge readiness check", "give this PR a review"
• "walk this diff", "review main...feature-branch", "review origin/main...HEAD"
• "review my staged changes", "review my working tree", "review this local diff"
• "validate this codex-review finding against the diff" (programmatic per-item mode)
• "the PR already has CodeRabbit/Copilot/Greptile comments — what's left to flag?"
• "cluster the changed files and flag the highest-risk ones"
• "this PR has 40 changed files; tell me what to look at first"
