What are Object Calisthenics constraints?

Object Calisthenics are a set of rules (such as 'no else keyword' or 'wrap all primitives') designed to force better object-oriented design and cleaner code structure.

How does the agent coordination work?

The skill manages transitions between three specialized states: the Tester (writes the failing test), the Implementer (writes minimal code to pass), and the Refactorer (cleans the code).

Does this skill support specific programming languages?

Yes, it can detect and configure toolchains for Rust, JavaScript, TypeScript, Python, and Java, following standard testing conventions for each.

Why does this skill use strict commit conventions?

Strict commits (e.g., test:, feat:, refactor:) provide a clear audit trail of the TDD cycle, helping developers and AI agents understand the context of every change.

A code kata is a practice exercise where you solve a small, well-defined problem repeatedly to build muscle memory for TDD cycles and clean code principles.

セキュリティとテスト

Facilitates professional Test-Driven Development practice by enforcing strict Red-Green-Refactor cycles and code kata constraints.

The TDD Kata Workflow skill transforms Claude into a disciplined development coach, guiding users through the rigorous Red-Green-Refactor cycle using the 'Three Laws of TDD.' It automates the orchestration between specialized agent roles—Tester, Implementer, and Refactorer—ensuring that production code is only written to satisfy failing tests and that design improvements occur only during dedicated refactoring phases. By incorporating Object Calisthenics constraints and tracking progress through structured TODO logs, it helps developers build deep muscle memory for clean code, minimal implementations, and professional testing standards.
