SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Python library maintainers often struggle with inconsistent linting, missing type hints, and brittle code that slows delivery. This skill standardizes quality by applying Ruff for linting/formatting, MyPy for type checking, and guidance for organizing project structure and refactoring.

Core Features & Use Cases

  • Ruff-based linting and formatting for Python code.
  • Strict typing through MyPy, with practical type hint patterns.
  • Project structure guidance and targeted refactoring to improve maintainability.
  • Use Case: preparing a Python library for public release or improving an existing codebase.

Quick Start

Run Ruff to lint and format Python code, then progressively add type hints and run MyPy to enforce type safety.

Frequently Asked Questions about improving-python-code-quality

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I enforce strict typing and linting in a Python library?▼

Enforce strict typing and linting by configuring Ruff for formatting and MyPy for type checking within a minimal pyproject.toml setup. This combination standardizes code quality by catching static analysis errors before runtime.

What is the best way to add type hints to an existing Python codebase?▼

The best way to add type hints is to apply them progressively alongside Ruff linting, then enforce the new hints using MyPy static analysis. This refactoring approach improves maintainability without breaking existing functionality.

Do I need a pyproject.toml file to configure Ruff and MyPy?▼

Yes, you need a minimal pyproject.toml file to configure Ruff and MyPy. Standard Python packaging practices require this setup to properly enforce static analysis rules across your project.

Can I use Ruff and MyPy together for static analysis?▼

Yes, using Ruff for linting and formatting alongside MyPy for type checking provides comprehensive static analysis coverage. This dual-tool approach catches both style violations and type errors in Python code.

Why does my Python code fail type checking when preparing for public release?▼

Python code fails type checking due to missing type hints or inconsistent typing patterns. Applying strict MyPy configuration and progressively adding type hints resolves these static analysis failures before release.
