What This Skill Does
A workflow guide for building full-stack applications, covering backend architecture, frontend-backend integration, auth, real-time features, and production hardening. It enforces a feature-first project structure, typed error handling, and structured logging across TypeScript, Python, and Go backends.
It replaces a dozen scattered docs with a single enforced workflow that catches common mistakes like scattered process.env usage, untyped errors, and N+1 queries before they reach production.
When to use it
- Scaffolding a new Express or Django API with proper service layers
- Wiring up a React frontend to a REST backend with typed API clients and error handling
- Adding JWT authentication with automatic token refresh to an existing app
- Implementing file uploads via presigned S3 URLs instead of streaming through the server
- Setting up SSE or WebSocket endpoints for live notifications or chat
