Review a single PR (or a local diff / branch) using a top-down three-layer method — (1) production-impact check (feature-flag gating, dead references), (2) chunk-level comprehension check (SOLID / DRY / YAGNI at the "does this shape make sense" altitude, not line-by-line), (3) surface check (shallow methods, patterns foreign to this repository). Use when the user wants to review a specific PR carefully, self-review their own working-tree change before pushing, or apply a consistent review discipline. Complements `smelly-prs` — that skill triages many merged PRs; this skill goes deep on one change. Read-only by default; never pushes, comments, or edits. Requires `gh` CLI when reviewing a remote PR. Invoke as `/layered-review <PR-url|PR-number|--diff>`.
Triage recently merged PRs of a GitHub repository and rank the ones that "smell" — God PRs, mixed concerns, missing tests, no reviewer, SOLID/DRY/KISS/YAGNI violations, GoF design-pattern misuse (Singleton abuse, missing Strategy/State, anemic domain, etc.), risky migrations, shotgun-surgery hotspots, and more. Use when the user wants to audit merge hygiene of a repo, find refactor candidates, hunt for risky merges to post-mortem, or pick suspicious PRs from a recent window. Requires the `gh` CLI to be authenticated against the target repo. Invoke as `/smelly-prs <owner/repo> [--limit N] [--since YYYY-MM-DD] [--base BRANCH]`.
