What problem does it solve? Engineers often start coding multi-step features without a clear roadmap, leading to missed requirements, inconsistent testing, and lost context. This Skill turns a spec or requirements document into a comprehensive implementation plan that any engineer 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 and Command References: Every task lists exact file paths to create or modify, complete code snippets, and test commands with expected output. - Execution Handoff: After saving the plan to docs/plans/YYYY-MM-DD-<feature-name>.md, it offers subagent-driven or parallel-session execution options. - Use Case: Given a feature spec for a new API endpoint, produce a plan document where each task includes the failing test code, the minimal implementation, the pytest command, and the git commit step. ## Quick Start Ask the AI to use the writing-plans skill to create an implementation plan from your feature spec before writing any code.
