What problem does it solve? Code reviews often produce inconsistent, subjective feedback or miss whether a change fits the codebase's long-term conventions, architecture boundaries, and public contracts. This Skill produces a structured, evidence-backed standards review of any code change — a GitHub PR, branch, local diff, or pasted diff — with a clear PASS, PASS WITH CONCERNS, or FAIL verdict. ## Core Features & Use Cases - Verdict-first report: Emits PASS / PASS WITH CONCERNS / FAIL computed mechanically from findings, in either a full gate mode (with a ten-dimension summary table) or a compact quick mode for local work. - Repo-authority-first review: Discovers AGENTS.md, CLAUDE.md, CONTRIBUTING, ADRs, lint configs, and adjacent exemplars before applying generic principles, so repo conventions override generic SOLID/DRY advice. - Ten review dimensions: Covers repo conventions, architecture boundaries, maintainability, domain model, SOLID/DRY change cost, tests, security, observability, API & semver compatibility, and DX/UX/accessibility. - Greenfield mode: Audits or scaffolds a new project's day-one foundations (CI-enforced formatting, lockfiles, ADRs, AGENTS.md) using the same severity model. - Use Case: Before merging a pull request, ask for a standards review; the Skill inspects the PR via gh, checks the diff against documented repo rules, runs targeted tests, and returns a gate report with file:line-cited findings and a recommended next step. ## Quick Start Review the current branch against main and give me a standards review verdict with evidence-backed findings.
