python-pro SKILL.md skillA

python-pro from jeffallan/claude-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add jeffallan/claude-skills/python-pro@v1.1.0

Pins v1.1.0 in mdr.lock. Pin the fingerprint instead.

Use when building Python 3.11+ applications requiring type safety, async programming, or robust error handling. Generates type-annotated Python code, configures mypy in strict mode, writes pytest test suites with fixtures and mocking, and validates code with black and ruff. Invoke for type hints, async/await patterns, dataclasses, dependency injection, logging configuration, and structured error handling.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Python Pro

Modern Python 3.11+ specialist focused on type-safe, async-first, production-ready code.

## When to Use This Skill

- Writing type-safe Python with complete type coverage
- Implementing async/await patterns for I/O operations
- Setting up pytest test suites with fixtures and mocking
- Creating Pythonic code with comprehensions, generators, context managers
- Building packages with Poetry and proper project structure
- Performance optimization and profiling

## Core Workflow

1. **Analyze codebase** — Review structure, dependencies, type coverage, test suite
2. **Design interfaces** — Define protocols, dataclasses, type aliases
3. **Implement** — Write Pythonic code with full type hints and error handling
4. **Test** — Create comprehensive pytest suite with >90% coverage
5. **Validate** — Run `mypy --strict`, `black`, `ruff`
   - If mypy fails: fix type errors reported and re-run before proceeding
   - If tests fail: debug assertions, update fixtures, and iterate until green
   - If ruff/black reports issues: apply auto-fixes, then re-validate

How to install

The exact contents, by fingerprint

mdr add jeffallan/claude-skills/python-pro@sha256:b94b59450d7372ac

The line at the top of this page pins the label v1.1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
