Generate production-ready Flask Cursor rules for Project Rules (.mdc), AGENTS.md, or legacy .cursorrules. This template encodes stack-specific conventions for projects using Flask. Lightweight Python micro-framework with Jinja templates and Werkzeug routing.
The template focuses Cursor AI on concrete Flask practices instead of generic coding advice. Required sections are always included; optional sections can be enabled when they match your project.
The generator turns these sections into Project Rules with frontmatter, AGENTS.md, or a single .cursorrules file depending on the output format you choose.
- Use the application factory pattern (create_app()).
- Use 4 spaces for indentation.
- Use snake_case for variables and functions.
- Use Blueprints for modular route organization.
- Register extensions in create_app() with init_app() pattern.
- Use app.config.from_object() and from_envvar() for configuration.- Use @bp.route() decorators within Blueprints.
- Use type hints for route parameters (<int:id>, <uuid:id>).
- Use request.get_json() for JSON request bodies.
- Return proper HTTP status codes for all responses.
- Use jsonify() or return dictionaries for JSON responses.
- Use url_for() for generating URLs — never hardcode paths.- Use @bp.errorhandler() for route-level error handling.
- Use @app.errorhandler() for application-level error handlers.
- Define custom exception classes with appropriate HTTP status codes.
- Use abort() with status codes for expected error scenarios.
- Log errors with traceback information in production.
- Return structured JSON error responses for API endpoints.
