描述
Work decomposition, dependency ordering, and status tracking for software tasks. Provides hierarchical decomposition (features into stories into leaf tasks), Slice-to-Task decomposition (walking skeleton first, then acceptance tests before implementation), GWT acceptance criteria on every task, explicit dependency declarations, estimated scope, and a strict lifecycle (Open/Active/Closed with one-at-a-time active task rule). Use when breaking down features, managing work items, tracking dependencies, creating stories or epics, slicing work for incremental delivery, or deciding what to work on next. Triggers on: "decompose this feature", "create tasks", "what should I work on next", "break this into smaller pieces", "walking skeleton", "slice into tasks", "task dependencies". Works with any task tool.
