SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill automates the GREEN phase of Test-Driven Development by implementing the minimal code required to make failing tests pass, coordinating specialist sub-agents for efficient development.

Core Features & Use Cases

  • Automated Test Passing: Implements code precisely as dictated by failing RSpec tests.
  • Sub-agent Orchestration: Delegates specific implementation tasks (migrations, models, services, etc.) to specialized AI agents.
  • Use Case: After writing failing tests for a new feature, you can invoke this Skill to automatically generate the necessary database migrations, model validations, and controller logic to make those tests pass.

Quick Start

Use the implementation agent to make the failing tests pass by implementing the minimal code required.

FAQPage Schema
How do I make failing RSpec tests pass automatically in Ruby on Rails?

To make failing RSpec tests pass, you can use an automated TDD green phase agent that implements the minimal Ruby on Rails code required to satisfy your failing test specifications.

What is the TDD green phase and how does automated code generation work?

The TDD green phase is the step where you write the minimal code to make failing tests pass. Automated code generation analyzes your failing tests and delegates implementation tasks to specialized subagents for efficient development.

Can I use this to generate Rails database migrations and models from failing specs?

Yes, you can generate Rails database migrations, model validations, and controller logic from failing specs. The agent orchestrates specialist subagents to implement each specific layer of your application.

What is the best way to automate code implementation after writing red phase tests?

The best way to automate code implementation after red phase tests is to invoke an agent that applies test-driven development principles, ensuring only the minimal code required to pass tests is generated.

Do I need to write failing tests before using an automated implementation agent?

Yes, you must write failing tests during the red phase first. The agent requires existing test specifications to analyze and determine the exact code needed to make them pass.

Why does my test-driven development workflow require manual coding for each layer?

Your TDD workflow requires manual coding because it lacks sub-agent orchestration. Delegating migrations, models, and services to specialized AI agents automates the green phase and eliminates manual implementation.
