What problem does it solve? Engineers often start coding multi-step features without a clear roadmap, leading to missed requirements, poor test coverage, and inconsistent execution. This Skill turns a spec or requirements document into a comprehensive implementation plan that any developer can follow, even with zero codebase context. ## Core Features & Use Cases - Bite-Sized Task Breakdown: Splits work into 2-5 minute steps following TDD: write failing test, verify failure, implement, verify pass, commit. - Exact File Paths and Code: Every task specifies exact files to create or modify, complete code snippets, and exact commands with expected output. - Execution Handoff: After saving the plan to docs/plans/, offers subagent-driven execution in the current session or parallel execution in a new session. - Use Case: You have a feature spec for adding user authentication. Run this Skill to produce a dated plan document with ordered tasks, test code, implementation code, and commit steps ready for execution. ## Quick Start Use the writing-plans skill to create an implementation plan for the feature spec I just described.
