What problem does it solve? When facing a multi-step feature or complex requirement, jumping straight into code leads to missed edge cases, vague assumptions, and rework. This Skill produces a concrete, step-by-step implementation plan saved as a markdown file, so execution becomes mechanical and reviewable before any code is written. ## Core Features & Use Cases - Plan-only mode: Inspects the repository with read-only commands and writes a plan without modifying project code, running mutating commands, or committing. - Structured plan format: Generates a markdown document with goal, architecture, tech stack, and bite-sized tasks (2-5 minutes each) containing exact file paths, complete copy-pasteable code, exact test commands with expected output, and commit steps. - TDD and execution handoff: Embeds test-driven development steps (failing test, minimal implementation, verification) in every coding task and hands off to subagent-driven-development for task-by-task execution with two-stage review. - Use Case: You ask for a plan to add user authentication. The Skill explores the codebase, then saves plans/2024-01-15_103000-add-auth.md with sequential tasks covering the User model, password hashing utility, failing tests, and verification commands. ## Quick Start Ask the agent to plan the implementation of your feature and save the plan under the plans directory without writing any code.
