PR Review Skill

If you are tasked with conducting a Pull Request review, generating feedback, or helping a user formulate a PR Review, you MUST immediately use the view_file tool to read and strictly adhere to .agents/skills/pr-review/references/pr-review-guide.md before proceeding.

Prior-art sweep gate (PR-review = the last line of defense, per AGENTS.md §verify_before_assert): before scoring, run a cheap 3–10-call query_raw_memories / query_summaries sweep of the PR's decision space — a prior session may have settled the shape, an ADR may already govern it, or the same wrong-shape may have been caught before. The sweep RESULT is the V-B-A; CI-green ≠ AC-met (#13354). Same gate, on your instrument: if the diff adds a capability gate / flag / new field, or your review is about to claim something is absent, load references/reviewer-instrument-audit.md — does satisfying the gate cause an effect or only describe one, does a production writer exist for the field, and does any "no caller" search carry a positive control plus the tree/SHA it ran against.

Templates: Round 1: load pr-review-template.md (full structure) — or, for a mechanical/micro PR per guide §6.4 eligibility, pr-review-micro-review-template.md (the blast-scaled light form). Round 2: load pr-review-round-2-template.md — disposition only, actions verbatim. Budget: ONE ordinary RC per reviewer family; at >24KB load audits/review-cost-circuit-breaker.md. Then approve/polish, A+FU, or one terminal D+S—never another ordinary RC.
