What problem does it solve? Vague or incomplete implementation plans force developers to guess at file paths, code details, and verification steps, causing bugs and rework. This Skill produces plans so detailed that an implementer with zero codebase context can execute them directly. ## Core Features & Use Cases - Bite-Sized Task Breakdown: Splits features into 2-5 minute tasks, each with exact file paths, complete copy-pasteable code, and exact commands with expected output. - TDD-Structured Tasks: Every coding task follows the full test-driven cycle: write failing test, verify failure, implement minimal code, verify pass, commit. - Execution Handoff: Saved plans integrate with subagent-driven-development for task-by-task execution with spec compliance and code quality reviews. - Use Case: Before building a multi-step feature like user authentication, generate a plan that decomposes it into tasks such as creating the User model, adding password hashing, and writing tests, each with exact paths and commands. ## Quick Start Ask the agent to write an implementation plan for your feature, breaking it into small TDD tasks with exact file paths and complete code, saved to docs/plans.
