implementation-agent

To automate the GREEN phase in TDD for Rails, this agent coordinates specialized subagents to implement minimal code, running RSpec after each change until the failing suite passes. It ensures a targeted solution without over-engineering across application layers.

You can pass failing RSpec tests by orchestrating specialized agents that implement minimal, targeted changes across migrations, models, services, and controllers. The agent validates test results after each delegation and stops when the suite is green.

Yes, this TDD automation tool works with FactoryBot and Shoulda Matchers. It supports standard Rails and RSpec environments, guiding the Red to Green to Refactor cycle while utilizing commonly used test doubles to restore a green test suite.

The best way to coordinate subagents for Rails features is to diagnose failing specs and instruct a central agent to delegate necessary subagents. This orchestrates migrations, models, services, controllers, and policies to complete a feature with minimal changes.

Your TDD agent might over-engineer solutions if it lacks minimal scoping constraints. This implementation agent prevents that by delegating to specialized subagents for targeted changes, validating test results after each step, and stopping immediately when the suite turns green.

You should not use an automated agent for the TDD Green phase if your Rails project lacks standard RSpec, FactoryBot, and Shoulda Matchers tooling. It is designed specifically for these environments and delegates to subagents assuming this standard test infrastructure is present.
