list-work-item-children-tool

Returns the child work items (sub-issues) of a work item — real work items linked to the parent through their parent_id, each with its own issue key. Rows are ordered by board position and match the shape returned by list-work-items-tool.

These are distinct from checklist subtasks: child work items are full work items you can transition, comment on, and link, while subtasks are lightweight to-do rows.

Inputs

Name	Type	Required	Description
`work_item_key`	string	yes	Issue key of the parent work item (e.g. `ACM-123`).
