Create an INDEPENDENT task for unrelated work. Use for: new topics, context switches, or parallel workstreams. Adds a new top-level task to your workspace. Previous task keeps its status. Example: working on Feature A, need to research Topic B → create_new_task for Topic B. For breaking down current work, use extend_current_task.

Add a subtask to organize and decompose work. Creates hierarchical structure for complex tasks. Subtasks help break down work into manageable pieces. You can work on tasks in any order using switch_focus. Example: Task A → Task B → Task C creates a nested structure, but you can jump between them freely. For unrelated work, use create_new_task.

Get the task with CURRENT status (your active focus). May be manually set via switch_focus, or automatically determined. In zen state (no tasks OR all tasks completed), returns appropriate message.

See ALL tasks in your task stack (including completed ones). Shows full work context as a living document. Marks current task with 'YOU ARE HERE'. Indicates zen state when no tasks exist OR all tasks are completed.

Mark current task as COMPLETED. Task remains visible in structure (living document approach). Focus automatically moves to a nearby incomplete task. Creates permanent record in history. You can use switch_focus to work on any specific task instead. Use remove_task to clean up workspace later.

View chronological history of ALL completed tasks. This is a permanent archive separate from the visible structure. Tasks remain here even after being removed from the workspace. Useful for reviewing what you've accomplished over time.

Update notes/content of the task you're currently focused on (current task only)

Get structured data of your entire task stack (JSON format with all task details and relationships)

Look at parent task and previous sibling without changing focus (understand WHY you're doing current task)

See all sibling tasks to the left of current focus. May include both pending and completed tasks. Helpful for understanding your position in the current task sequence.

Switch focus to ANY task by ID. The primary way to navigate your task workspace - jump between tasks in any order, revisit completed work, or change priorities on the fly. Current task retains its status, target task becomes current. Use get_big_picture or get_stack_overview to see task IDs.

Remove a task from the structure (cleanup your workspace). The task remains in completed_tasks history if it was completed. Can remove any task (completed or not). Removing a parent task removes all its subtasks. Use get_big_picture or get_stack_overview to see task IDs.
