What problem does it solve? Code reviews often suffer from scope creep, inconsistent formats, and reviewers flagging issues outside their mandate. This Skill enforces single-focus, diff-only code review with a fixed output template so findings are consistent, parseable, and routed correctly. ## Core Features & Use Cases - Single-focus review: Resolves one focus brief (accuracy, architecture, or dx), adopts the named persona, and reviews exactly one diff without fanning out to subagents. - Diff resolution: Accepts a .diff/.patch file, source file, or directory and derives the change via git diff against a configurable base ref, with an explicit empty-diff fallback. - Standardized output: Writes one rNN-{focus}.md file with fixed Blockers/Majors/Minors/Nits sections so downstream triage tooling can parse every review uniformly. - Use Case: An orchestrator like validate-code dispatches three parallel reviews of a pull request diff — one accuracy, one architecture, one dx — and each returns a consistently formatted findings file for triage-feedback to merge. ## Quick Start Ask the agent to review the current branch diff against master using the architecture focus and write the findings file to the review directory.
