Send "type": "checklist".

Create a checklist / to-do list of actionable tasks with checkboxes. Use this for task lists, action items, checklists, shopping lists, project task breakdowns, or any content organizing things that need to be completed. For status-column task boards use render_kanban; for scheduled tasks with durations use render_gantt.

Also available as the MCP tool render_checklist. The same payload works through either surface.
