tdd-collaboration

What problem does it solve?

This Skill enforces a strict, collaborative Test-Driven Development (TDD) workflow, ensuring every line of code is driven by a failing test. It guides you through the Red → Domain → Green cycle, preventing over-implementation, promoting minimal design, and guaranteeing a robust, well-tested codebase.

Core Features & Use Cases

• Guided Red Phase: Collaboratively write one test with one assertion, ensuring it fails (Red) before any implementation.
• Guided Domain Phase: Collaboratively define minimal types and interfaces to make the test compile, focusing on domain modeling.
• Guided Green Phase: Collaboratively implement only the code necessary to make the failing test pass (Green), strictly avoiding anticipatory features.
• Use Case: Adopt a rigorous TDD approach with AI guidance, ensuring every line of code is driven by a failing test. Collaborate on test design, type definitions, and minimal implementations to build robust, well-tested software.

Quick Start

Initiate a TDD cycle for a new story or feature.

The AI will propose the first test based on the story requirements.

You will review and modify it directly via your IDE.

Example interaction in Rust:

AI proposes:

#[test]

fn test_payment_capture_valid_amount() { /* ... */ }

User adds:

// QUESTION: Should we also test negative amounts here or separately?
