What problem does it solve? Engineers often start coding from a spec without a clear roadmap, leading to missed requirements, inconsistent types, and vague tasks. This Skill turns a spec or requirements document into a complete, bite-sized implementation plan 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 TDD: write failing test, verify failure, implement, verify pass, commit. - No-Placeholder Enforcement: Every step includes exact file paths, complete code blocks, exact commands, and expected output — no TODOs or vague instructions. - Self-Review Checklist: Validates spec coverage, scans for placeholder patterns, and checks type/name consistency across tasks before saving. - Use Case: Given a feature spec for a new API endpoint, produce a plan saved to docs/plans/ with checkbox-tracked tasks, then hand off to subagent-driven or inline execution. ## Quick Start Use the writing-plans skill to turn this feature spec into a step-by-step implementation plan saved under docs/plans.
