What problem does it solve? Backend changes often get declared done based on stale CI runs, typecheck passes, or vague manual smoke tests. This Skill turns a closeout question into a disciplined readiness verdict by mapping each changed claim to the smallest check that can actually falsify it. ## Core Features & Use Cases - Proof Obligation Mapping: Names the exact claims that need evidence across contract, Fastify runtime, Prisma/Postgres, Redis, workflow-state, and test-harness seams. - Smallest Honest Layer Selection: Chooses between typecheck, unit, route inject, contract diff, real Postgres/Redis integration, migration preflight, and targeted runtime proof instead of defaulting to the broadest suite. - Readiness Verdict Discipline: Classifies evidence as fresh direct, partial, stale, indirect, or missing, then issues verified ready, conditionally ready, or not yet verified verdicts with explicit residual risk. - Use Case: After changing a Fastify route with a new Prisma migration, ask whether the change is ready and receive a claim-by-claim proof plan naming the exact route inject test and migration preflight still required. ## Quick Start Ask the agent to verify whether your current TypeScript backend change is actually ready to close out and what proof is still missing.
