What problem does it solve? Reviewing a diff consistently is hard: reviewers miss surrounding contracts, conflate severity with confidence, invent findings to avoid empty reports, or treat an unavailable diff as "no issues." This Skill structures diff review so every material finding carries evidence, impact, confidence, and a canonical label. ## Core Features & Use Cases - Effective diff scoping: Establishes the exact reviewed range (commit range, PR diff, or staged/unstaged/untracked files) before reviewing, and reports when no diff can be obtained instead of claiming no issues. - Structured finding contract: Each finding gets one canonical label (must/should/suggestion/question/nit/note), a confidence level, evidence, impact, verification method, and an explicit Unconfirmed premises field so downstream triage needs no re-investigation. - Full re-review reconciliation: On explicit re-review, classifies previous findings as Resolved, Remaining, or New, and tags each New finding as Fix-induced, Newly observable, or Late-discovered. - Use Case: Before merging a pull request, ask for a review of the PR diff; the Skill inspects surrounding contracts, callers, and tests, runs safe non-mutating checks, and returns findings ordered by requested response and impact, plus unchecked scope and residual risk. ## Quick Start Review the current staged and unstaged changes in this repository and report material findings with labels, confidence, evidence, and residual risk without editing any files.
