What problem does it solve? Turning a spec or requirements document into an actionable implementation plan is error-prone: engineers get vague tasks, missing file paths, and placeholder steps that stall progress. This Skill produces complete, self-contained implementation plans that an engineer with zero codebase context can execute task by task. ## Core Features & Use Cases - Bite-Sized Task Decomposition: Breaks work into 2-5 minute steps following a strict TDD cycle (failing test, verify failure, minimal implementation, verify pass, commit). - No-Placeholder Enforcement: Requires exact file paths, complete code blocks, exact commands with expected output, and bans vague instructions like "add error handling" or "TBD". - Self-Review & Execution Handoff: Runs a spec-coverage, placeholder, and type-consistency check, then offers subagent-driven or inline execution of the finished plan. - Use Case: After brainstorming a new feature spec, invoke this Skill to produce a dated plan document in docs/superpowers/plans/ with checkbox-tracked tasks ready for subagent-driven implementation. ## Quick Start Ask the AI to use the writing-plans skill to turn your feature spec into a step-by-step TDD implementation plan saved under docs/superpowers/plans/.
