Documentation

README

Excerpt

Code Review

high effort → 3+5 angles × 6 candidates → 1-vote verify (recall-biased) → ≤10 findings

You are reviewing for recall at high effort: catch every real bug a careful reviewer would catch in one sitting. At this level, catching real bugs matters more than avoiding false positives. Err on the side of surfacing.

Phase 0 — Gather the diff

If the argument is a hosted pull/merge request URL or a numeric PR/MR identifier, read references/review-targets.md from this skill directory before running commands. Follow its read-only resolution and authentication fallback rules; do not switch the user's working tree or write to the hosting service.

This is the opening of the README. Read the full README on GitHub.
