What problem does it solve? Backend code often ships with hidden production risks: missing idempotency keys, absent graceful shutdown handlers, unsafe database migrations, and no observability. This Skill audits services, APIs, and schemas against production-grade standards and returns specific, actionable findings. ## Core Features & Use Cases - Six Audit Dimensions: Checks idempotency, observability, graceful shutdown, migration discipline, API design, and reliability/scalability with concrete checklists. - Prioritized Audit Report: Produces findings ranked Critical/Important/Improvement with scores for observability, idempotency, and shutdown safety. - Corrected Code & Migration Review: Generates fixed implementations for critical findings and Expand-Migrate-Contract sequences for schema changes. - Use Case: Paste your Fastify route files and Prisma migrations before a deploy, and receive a report flagging a missing SIGTERM drain handler, an unsafe NOT NULL column addition, and N+1 queries — each with the corrected code. ## Quick Start Ask the AI to audit your backend service code or migration files for production readiness using this skill.
