What problem does it solve? Backend services often ship with hidden production risks: missing idempotency keys, no graceful shutdown handling, unsafe database migrations, and absent observability. This Skill systematically audits backend code, API designs, and migration strategies against production-grade engineering standards, producing specific findings with quantified risks and corrected code. ## Core Features & Use Cases - Six-Dimension Audit: Checks idempotency contracts, observability (traces/metrics/logs), graceful shutdown sequences, expand-migrate-contract migration discipline, API design correctness, and reliability/scalability patterns. - Prioritized Audit Report: Produces findings tiered as Critical, Important, and Improvements, each with specific location, risk, and fix, plus numeric scores for observability, idempotency, and shutdown safety. - Corrected Code & Migration Review: Generates fixed implementations with inline before/after comments and a migration safety analysis covering breaking changes, lock duration, and rollback strategy. - Use Case: Before deploying a Fastify service, paste your route handlers and Prisma migration files to receive a full audit report flagging a missing SIGTERM drain handler and an unsafe NOT NULL column addition, along with the corrected code. ## Quick Start Ask the AI to audit your backend service code or migration files for production readiness using this skill.
