What problem does it solve? Large or vague work items cause agents and developers to produce tangled, unreliable implementations. This Skill turns a spec or clear requirements into small, ordered tasks with explicit acceptance criteria, verification steps, and dependency mapping. ## Core Features & Use Cases - Structured Planning Process: Read-only plan mode, dependency graph mapping, and vertical slicing so each task delivers working, testable functionality. - Task Templates and Sizing: A standard task format with acceptance criteria, verification commands, dependencies, and sizing guidelines (XS through XL) that force oversized work to be split. - Flexible Output Targets: Writes plans to tasks/plan.md and task lists to tasks/todo.md by default, or maps tasks onto external trackers like GitHub Issues, Jira, or Linear, with safeguards against overwriting incomplete plans. - Use Case: Given a spec for a user authentication feature, produce a plan document plus an ordered checklist of tasks (schema, API, UI slices) with checkpoints after each phase. ## Quick Start Ask the agent to read the attached spec and break the work into an ordered task list with acceptance criteria saved to tasks/plan.md and tasks/todo.md.
