The registry for agent skills.
Audits a backend or API for security vulnerabilities, stability bugs, and design flaws, explains each one in plain language, then fixes them on request. Covers authentication, authorization and IDOR, injection, input validation, exposed secrets, database and transaction correctness, race conditions, error handling, rate limiting, and deployment config across any language or framework including Node/Express/Nest/Fastify/Next, Python/Django/FastAPI/Flask, PHP/Laravel, Ruby/Rails, Go, Java/Spring, .NET, and Supabase/Firebase. Use whenever the user asks to review, audit, secure, harden, or production-proof a backend or API; asks whether their backend is safe, secure, or ready to launch; mentions vulnerabilities, auth bugs, SQL injection, exposed API keys, or leaked secrets; is about to deploy a backend; or has AI-generated backend code they do not fully understand. Also use proactively when writing or editing server-side route handlers, database queries, or auth logic.
