What problem does it solve? Turning a spec or requirements document into an actionable implementation plan is error-prone: tasks end up too vague, file paths are missing, and engineers without codebase context get stuck. This Skill produces a complete, bite-sized task plan that an engineer (or subagent) with zero context can execute directly. ## Core Features & Use Cases - Structured Plan Documents: Generates plans with a mandatory header (goal, architecture, tech stack, global constraints) and per-task blocks listing exact files to create or modify, interfaces consumed and produced, and checkbox steps. - Bite-Sized TDD Tasks: Breaks work into 2-5 minute steps following a failing-test, implement, verify, commit cycle, with complete code and exact commands in every step. - Self-Review and Handoff: Runs a spec-coverage, placeholder, and type-consistency check, then offers subagent-driven or inline execution of the finished plan. - Use Case: Given a feature spec for a new API endpoint, produce a dated plan file in docs/superpowers/plans/ with tasks covering tests, implementation, and commits that a fresh subagent can execute task-by-task. ## Quick Start Ask the AI to use the writing-plans skill to create an implementation plan from your spec before writing any code.
