If you're building anything beyond a basic Flask app, this skill covers the patterns you actually need: application factories, blueprints, SQLAlchemy models with relationships, and JWT authentication that doesn't leave security holes. It walks through Flask-RESTful resources with proper request parsing and response marshalling, plus the extensions ecosystem (Flask-Migrate, Flask-CORS, Flask-Limiter) that turns Flask from a microframework into something production-ready. The code examples show real implementations, not toy demos, like handling pagination, protecting routes with decorators, and structuring endpoints that won't make you cringe during code review. Good for when you're past hello world but before you've memorized every Flask extension's quirks.
