SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Automates the execution of design-phase work in a TDD-driven workflow by selecting and running red-green-refactor cycles for tasks in a plan, coordinating collaboration, and preserving session state.

Core Features & Use Cases

  • Orchestrates end-to-end TDD phase execution by loading plan.md, determining which tasks to run, and performing red-green-refactor cycles.
  • Spawns subagents for independent tasks within a phase and coordinates parallel work while avoiding conflicts.
  • Enforces preflight checks, commit discipline, and post-phase review to ensure safety and traceability.

Quick Start

Ask Claude to execute the next incomplete phase for a given design by name, and it will guide you through selection, confirmation, and the red-green-refactor workflow.

FAQPage Schema
How do I automate red-green-refactor cycles for tasks in a design plan?

To automate red-green-refactor cycles, you orchestrate end-to-end TDD phase execution by loading a valid plan.md, determining which tasks to run, and performing the cycles while coordinating parallel work and enforcing commit discipline.

Can I run independent TDD tasks in parallel using agent orchestration?

Yes, agent orchestration spawns subagents for independent tasks within a phase. It coordinates parallel work to avoid conflicts while executing the red-green-refactor cycles concurrently for those independent tasks.

What do I need to start TDD phase execution for a given design?

To start TDD phase execution, you need a valid docs/tdd-designs/<design-name>/plan.md file and must adhere to preflight collaboration and commit conventions before running the red-green-refactor cycles.

How does a TDD workflow handle commit discipline and post-phase review?

A TDD workflow enforces commit discipline and post-phase review through preflight checks before executing red-green-refactor cycles, ensuring safety and traceability across all staged design-phase work.

When should I use multi-phase TDD orchestration instead of single-phase?

Use multi-phase TDD orchestration when your design plan contains multiple dependent stages requiring staged execution, whereas single-phase suffices for isolated task sets within one red-green-refactor cycle.
