planning-and-task-breakdown

What problem does it solve? Large or vague work items cause agents to produce tangled, unverifiable implementations. This Skill turns a spec or clear requirements into small, ordered tasks with explicit acceptance criteria, dependencies, and checkpoints so implementation stays on track. ## Core Features & Use Cases - Structured Planning Process: Guides read-only plan mode, dependency graph mapping, and vertical slicing so each task delivers working, testable functionality. - Task Templates and Sizing: Provides a task format with acceptance criteria, verification steps, dependencies, and size guidelines (XS through XL) to keep tasks small enough for a single focused session. - Plan and Todo Outputs: Produces a plan document at tasks/plan.md and a checklist at tasks/todo.md, including phases, checkpoints, risks, and open questions. - Use Case: Given a spec for a user authentication feature, generate a phased task list covering schema, API, and UI slices with checkpoints after each phase before any code is written. ## Quick Start Ask the agent to break your feature spec into an ordered task list with acceptance criteria and save the plan to tasks/plan.md and tasks/todo.md.
