Call once after `until_done_set`. The list is written to `.until-done/tasks.yaml` for human review.",

The North Star (goal, doneCriteria, verifyCommand, askBefore) is LOCKED — call `/until-done cancel` if you need to change those. `done` tasks are immutable. Every call must include a `reason` (one short sentence) which is appended to affected tasks' learnings.",

		"Pause the /until-done loop because user input is needed. Use when ask-before is triggered, when ambiguity blocks progress, or when an external dependency is missing.",
