This is a well-maintained Flask skill that focuses on production patterns rather than toy examples. It covers the application factory pattern, Blueprints, and Flask-SQLAlchemy integration, which is exactly what you need when moving beyond tutorial-level Flask apps. The version tracking is current as of January 2026, and it includes the modern Flask ecosystem (Flask-Login, Flask-WTF, Werkzeug). With 430 installs and 819 GitHub stars, it has some community validation. If you're building anything more complex than a single-file Flask app, the patterns here will save you from reorganizing your project structure later when things get messy.
