What is the PIV methodology mentioned in the repository?

PIV stands for Prime-Implement-Validate, a structured specification and implementation methodology specifically designed to optimize AI-assisted development.

Which programming languages does this skill support?

This skill supports a wide range of popular languages including Java, TypeScript, JavaScript, Python, and Go.

How does this improve AI-generated code?

By forcing the AI to define requirements via tests first, it reduces hallucinations and ensures the resulting code meets specific, verifiable functional requirements.

What is the TDD Claude Code Skill?

It is a specialized capability that enforces a strict test-driven development workflow, requiring failing tests to be written before any functional code is implemented.

What happens if implementation code is written before a test?

The skill follows a strict 'Code before tests → DELETE' rule to ensure the integrity of the TDD methodology and prevent technical debt.

보안 및 테스팅

Enforces the strict Red-Green-Refactor cycle to ensure high code quality and test coverage in AI-assisted development.

The TDD Skill implements a rigorous Test-Driven Development methodology within Claude Code, following the PIV (Prime-Implement-Validate) framework. It prevents the AI from generating implementation code before a corresponding failing test exists, mandating a workflow of writing a failing test (Red), implementing the minimal code necessary to pass (Green), and then optimizing the solution (Refactor). This skill is essential for developers looking to eliminate technical debt, improve software reliability, and maintain a high-quality codebase across multiple programming languages including Java, Python, and TypeScript.
