SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Automates and guides a test-driven development workflow with AI agents, turning vague feature ideas into executable tests early to improve code quality and reduce debugging time.

Core Features & Use Cases

  • Guided Red-Green-Refactor cycles with AI agents.
  • Automated test generation from user stories or requirements.
  • Iterative debugging: AI suggests minimal implementations to make tests pass with safety checks.

Quick Start

Describe a feature scenario to the AI agent and let it generate failing tests, implement minimal code, and iterate until tests pass.

FAQPage Schema
How do I use AI agents for test-driven development in TypeScript?

Test-driven development with AI agents involves guiding the AI to write failing tests first, then suggesting minimal implementations to pass them. This Skill automates that workflow by generating executable Vitest tests from your feature scenarios.

What is the Red-Green-Refactor cycle and how can AI automate it?

The Red-Green-Refactor cycle is writing a failing test, making it pass, then refactoring. This Skill automates the cycle by having the AI generate tests, write minimal code to pass them, and iterate with safety checks to ensure code quality.

Can I automatically generate Vitest tests from feature requirements?

Yes, you can automatically generate Vitest tests from feature requirements. By describing a user story or scenario to the AI, it will generate the corresponding failing tests early to anchor development and reduce debugging time.

How do I ensure safe code refactoring when using AI for TDD?

Safe code refactoring with AI is ensured through iterative debugging and safety checks. After tests pass, the AI suggests refactoring steps while maintaining the existing test suite as a safety net to prevent regressions.

Does this TDD workflow support Vitest and TypeScript?

Yes, this TDD workflow explicitly supports Vitest and TypeScript. It is designed to integrate with your existing TypeScript testing setup to automate test creation and guide the Red-Green-Refactor cycles.
