What problem does it solve? Turning a feature spec into code without a clear plan leads to missed requirements, inconsistent structure, and untested changes. This Skill converts requirements into a comprehensive, step-by-step implementation plan that any engineer can execute without prior codebase context. ## Core Features & Use Cases - Bite-Sized Task Breakdown: Splits work into 2-5 minute steps following a strict TDD cycle: write failing test, verify failure, implement, verify pass, commit. - Standardized Plan Format: Produces a Markdown plan saved to docs/plans/ with exact file paths, complete code snippets, exact commands, and expected outputs. - Execution Handoff: Offers subagent-driven execution in the current session or parallel-session execution with an executing-plans skill. - Use Case: Given a spec for a new API endpoint, generate a plan document listing every file to create or modify, the tests to write first, and the commit sequence, ready for task-by-task execution. ## Quick Start Ask the assistant to use the writing-plans skill to create an implementation plan for your feature spec before writing any code.
