Can I use this for fixing existing bugs?

Absolutely. The workflow encourages writing a failing test that reproduces the bug before implementing the fix to ensure the issue is resolved and won't regress.

Does this skill provide output in Japanese?

Yes, all user-facing output, reports, and summaries are generated in Japanese, while internal reasoning is kept in English.

What is the default coverage requirement?

The skill enforces a minimum of 80% code coverage for general code, with a target of 90%+ for public APIs and 100% for critical business logic.

How does it handle complex dependencies?

It utilizes standard Python mocking patterns and pytest fixtures to isolate units of code and simulate external API or database behaviors.

What testing frameworks does this skill support?

This skill is optimized for pytest, utilizing pytest-cov for coverage reporting, pytest-asyncio for async operations, and pytest-xdist for parallel execution.

Enforces a strict Red-Green-Refactor development cycle for Python using pytest and automated coverage verification.

The Python TDD Workflow skill transforms Claude into a test-driven development specialist, ensuring high-quality Python code through the Red-Green-Refactor cycle. It prioritizes writing failing pytest tests before any implementation and mandates a minimum of 80% code coverage to ensure reliability. This skill is particularly useful for building mission-critical logic, fixing bugs with regression tests, and maintaining complex codebases. While internal reasoning is performed in English, all user-facing reports and summaries are provided in Japanese, making it ideal for Japanese-speaking development teams following strict QA standards.
