Individual skill

breakdown

Break an epic or a design document into owned, sequenced tasks: one deliverable each, an owner, a dependency order, the parallel lanes that avoid two people editing the same file, and a definition of done per task. Use before a sprint starts, when work has to be shared across several developers, or when a piece of work needs owners and parallel lanes. Work that stays with one person is planned with `atk:plan` instead, however many days it takes. Triggers on: "break down", "breakdown", "chia task", "phân chia công việc", "split this epic", "task list", "WBS", "タスク分解", "who does what", "assign tasks", "/atk:breakdown".

# Task Breakdown (`atk:breakdown`)

Turns one large piece of work into tasks a team can run at the same time without colliding. The
value is in the dependency order and the file ownership, not in the list itself.

## Scope

Handles: decomposing an epic or design into tasks, assigning an owner to each, ordering by
dependency, grouping into parallel lanes with explicit file ownership, and writing a per-task
definition of done.

Does NOT handle: sizing (`atk:estimate`), designing the solution (`atk:design-doc`), or
implementation. It divides work between people; how one person's share is then carried out, in
phases and steps, is `atk:plan`, which the assignee writes for themselves afterwards. Work that
