What problem does it solve? Teams need an objective, read-only quality gate before merging code. This Skill inspects changed files against contracts, types, tests, security baselines, and schema alignment, then issues an evidence-backed verdict so nothing ships unverified. ## Core Features & Use Cases - Tiered Verification: Choose Lite (quick fixes, ≤2 files), Standard (route contracts, schema alignment, security baseline), or Full (threat model, security headers, npm audit, runtime proof) depending on the Work Block's risk. - Structured Verdicts: Outputs a JSON verdict of READY, BLOCKED, or UNVERIFIED with per-check PASS/FAIL status, evidence, blockers with file and line references, and non-blocking warnings. - Read-Only Safety: Runs git diff, tests, curl, and security scans without editing production code, committing, or accessing secrets. - Use Case: Before merging an authentication change, run a Full-tier verification to confirm route contracts, run npm audit, check security headers, and receive a BLOCKED verdict with exact file and line evidence if anything fails. ## Quick Start Ask the agent to verify the current Work Block at standard tier and return a READY, BLOCKED, or UNVERIFIED verdict with evidence.
