What problem does it solve? Multi-step features often get implemented without a clear plan, leading to vague tasks, missing context, and inconsistent code. This Skill produces detailed implementation plans that assume the implementer has zero context for the codebase, so execution becomes obvious rather than guesswork. ## Core Features & Use Cases - Bite-Sized Task Breakdown: Splits work into 2-5 minute tasks, each with exact file paths, complete copy-pasteable code, and verification commands. - TDD-First Structure: 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 delegation with two-stage review. - Use Case: Before building a new API endpoint, generate a plan that lists each file to create or modify, the complete code for each step, the exact pytest commands to run, and the expected output, then hand it to a subagent for execution. ## Quick Start Ask the agent to write an implementation plan for your feature after completing a brainstorming phase, and it will produce a task-by-task plan saved to docs/plans/.
