What does this skill do?

The Python Developer skill is an open-source skill that establishes production-quality standards for modern Python 3.12+ codebases.

It requires type hints, a src/ layout, and current tooling — uv, ruff, ty or mypy, and pytest — and covers modern syntax, dataclasses with slots, pattern matching, and async task groups.

It also includes a priority-based code-review framework and security imperatives, with version-specific guidance for Python 3.12, 3.13, and 3.14.

  • Enforces modern type hints and project structure

  • Uses uv, ruff, ty/mypy, and pytest tooling

  • Covers async patterns, dataclasses, and pattern matching

  • Provides a priority-based code-review framework

How it works

1

Set up the project

The agent scaffolds a src/ layout with pyproject.toml as the single source of truth and current tooling defaults.

2

Write typed, modern code

It uses modern type hints, dataclasses with slots, pattern matching, pathlib, and async task groups with error handling.

3

Test and secure

It writes pytest tests with mocking and applies security imperatives — parameterized queries, secret management, and safe input handling.

4

Review by priority

It reviews code by priority — critical security and correctness first — commenting only with high confidence.

Best use cases for this skill

  • New projects: Scaffold a modern Python 3.12+ project with the right tooling.

  • Code review: Review Python PRs by priority with a security-first focus.

  • Modernization: Update a codebase to modern type hints and pathlib.

  • Async work: Write async code with task groups and proper error handling.

Frequently asked questions

What does the Python Developer skill do?

It helps an agent write modern Python 3.12+ following current best practices — type hints, uv, ruff, pytest, async patterns, and project structure — plus a code-review framework.

When should an agent use it?

Use it when creating Python 3.12+ projects, reviewing Python code, refactoring, or answering questions about project structure, typing, testing, or async.

Which tooling does it standardize on?

uv for dependencies, ruff for linting and formatting, ty (or mypy for established projects) for type checking, and pytest for testing, with a mandatory src/ layout.

Does it cover code review?

Yes. It includes a priority-based review framework — critical security and correctness first — and an autonomous CI mode with comment limits.
