Implementation

Use when you have a spec or requirements for a multi-step task, before touching code

Use when executing implementation plans with independent tasks in the current session

This skill helps create detailed implementation plans that break down software features into executable tasks following Test-Driven Development (TDD) principles. It provides templates, examples, and validation checklists to ensure plans are complete, traceable to specifications, and can be followed independently by developers.

This skill helps manage complex implementation plans by breaking them into phases and executing tasks systematically. It tracks progress with TodoWrite, handles parallel task delegation to agents, validates checkpoints before proceeding, and always pauses for user confirmation between phases.
