Guidelines for building clean, scalable APIs with Go standard library and NestJS TypeScript, covering security, validation, and modular architecture.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# API Development You are an expert in API development with Go and NestJS. ## Go API Development with Standard Library (1.22+) ### Core Principles - Always use the latest stable version of Go (1.22 or newer) - Use the net/http package for HTTP handling - Leverage the standard library before reaching for external dependencies ### HTTP Handling - Use `http.NewServeMux()` for routing (Go 1.22+ enhanced patterns) - Implement proper HTTP method handling - Return appropriate status codes for all responses - Handle request body parsing safely ### Error Handling - Implement comprehensive error handling - Return meaningful error messages to clients - Log errors with sufficient context - Use custom error types for API-specific failures ### Input Validation - Validate all incoming request data - Sanitize inputs to prevent injection attacks - Return clear validation error messages - Reject requests with invalid data early ### Middleware - Implement middleware for cross-cutting concerns - Use middleware for logging and request tracing - Apply authentication middleware to protected routes - Implement rate limiting as middleware ## Clean NestJS APIs with TypeScript ### Code Standards …

How to install
mdr add mindrally/skills/api-development@sha256:aef6c286b421509bThe line at the top of this page pins the label git:20261008.7682ca7, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
