What problem does it solve? Vague or incomplete implementation plans cause bugs, wasted effort, and failed handoffs when developers or subagents lack context about a codebase. This Skill produces detailed implementation plans where every task is small, explicit, and verifiable, so execution becomes obvious. ## 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 verification commands. - TDD-Structured Tasks: Every coding task follows the full test-driven development cycle: failing test, minimal implementation, passing verification, and 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 authentication feature, generate a plan that decomposes it into tasks like creating the User model, adding password hashing, and writing tests, each with exact commands and expected output. ## 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.
