SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill audits Flask projects for app structure, extension usage, request handling, and testing practices to reduce bugs and improve maintainability.

Core Features & Use Cases

Application structure: evaluates blueprint organization and factory patterns.
Extension configuration: checks proper init_app patterns and extension setup.
Request handling: validates requests, handles errors, and improves validation.
Testing & security basics: suggests test coverage and basic security checks.
Use Case: Restructure a Flask app to use an application factory and blueprints with validated requests.

Quick Start

Run the flask-reviewer on a Flask project to obtain an actionable improvement list for structure and request handling.

FAQPage Schema

How do I structure a Flask app with blueprints and an application factory?▼

Flask application factories and blueprints organize code into modular, testable units. A factory function creates and configures the app instance, while blueprints group related routes and logic. This pattern improves maintainability, enables testing, and simplifies configuration management across environments.

What should I validate in Flask request handling?▼

Request validation in Flask covers input data types, required fields, and format constraints before processing. Proper validation prevents bugs, improves error handling, and strengthens security. Tools like marshmallow or Flask-Inputs streamline schema definition and error reporting.

How do I properly configure Flask extensions?▼

Flask extensions should use the init_app pattern: initialize the extension object without an app, then call init_app during application creation. This pattern enables multiple app instances, simplifies testing, and prevents circular import issues.

What testing practices should a Flask project follow?▼

Flask projects benefit from unit tests covering route handlers, integration tests validating request/response flows, and fixtures for app and database setup. Adequate test coverage catches bugs early and ensures refactoring doesn't break functionality.

Can flask-reviewer work with REST APIs?▼

Yes. Flask-reviewer analyzes Flask projects featuring RESTful APIs, examining blueprint organization, request/response handling, error handling patterns, and testing practices to ensure API reliability and maintainability.
