Cancel Swarm

Stop any active swarm workers.

Works with all swarm commands: `/implement-swarm`, `/plan-swarm`, `/tasks-swarm`, `/beads-swarm`.

Note: Loop and swarm commands are interchangeable - use `/cancel-swarm` for swarms and `/cancel-loop` for loops.

Instructions

1. Call TaskList to see all tasks and their status 2. For any tasks with status `in_progress`:

• Note the owner (worker name)
• The worker may still be running

3. Use TaskStop to halt any background workers still active 4. Report:

• Completed tasks: N
• In-progress (interrupted): N
• Pending (not started): N

If no in-progress tasks found:

• Say "No active swarm found."

After Cancellation

Task progress is preserved:

• Completed tasks remain completed
• In-progress tasks may complete if worker finishes
• Pending tasks remain pending

To check task status:

TaskList

Note

Unlike loop cancellation, swarm workers are independent agents. If a worker completed its current task before cancellation, that work is saved. For Agent Teams (tmux-based), use `/cancel-team` instead.
