Implementation Planning Skill

Use this skill to convert a spec.md into a step-by-step TDD implementation plan.

Protocol

1. Context Scan: Analyze existing code and relevant interfaces in the target module.
2. Phase Breakdown:
   • Phase 0: Environment & Baseline (Tests that fail).
   • Phase 1: Core Implementation.
   • Phase 2: Refinement, Documentation, and Edge Case Tests.
3. Atomic Steps: Ensure every step is a discrete, verifiable unit of work.

Validation

Before finalize the plan.md, check:

• Does every requirement in spec.md have a corresponding test step?
• Are file paths resolved according to the project structure?

Execution Mandate

The plan.md is a live tracking document. Agents must:

1. Reference the plan.md at the start of every implementation session.
2. Mark steps as completed ([x]) in plan.md as they are finished and verified.
3. Keep the user informed of progress by referencing the plan's milestones.
