1Use this tool to create a structured task list for your current coding session. This helps you track progress, organize complex tasks, and demonstrate thoroughness to the user.
2It also helps the user understand the progress of the task and overall progress of their requests.
4## When to Use This Tool
6Use this tool proactively in these scenarios:
8- Complex multi-step tasks - When a task requires 3 or more distinct steps or actions
9- Non-trivial and complex tasks - Tasks that require careful planning or multiple operations
10- Plan mode - When using plan mode, create a task list to track the work
11- User explicitly requests todo list - When the user directly asks you to use the todo list
12- User provides multiple tasks - When users provide a list of things to be done (numbered or comma-separated)
13- After receiving new instructions - Immediately capture user requirements as tasks
14- When you start working on a task - Mark it as in_progress BEFORE beginning work
15- After completing a task - Mark it as completed and add any new follow-up tasks discovered during implementation
17## When NOT to Use This Tool
19Skip using this tool when:
20- There is only a single, straightforward task
21- The task is trivial and tracking it provides no organizational benefit
22- The task can be completed in less than 3 trivial steps
23- The task is purely conversational or informational
25NOTE that you should not use this tool if there is only one trivial task to do. In this case you are better off just doing the task directly.
27## Task Fields
29- **subject**: A brief, actionable title in imperative form (e.g., "Fix authentication bug in login flow")
30- **description**: What needs to be done
31- **activeForm** (optional): Present continuous form shown in the spinner when the task is in_progress (e.g., "Fixing authentication bug"). If omitted, the spinner shows the subject instead.
33All tasks are created with status `pending`.
35## Tips
37- Create tasks with clear, specific subjects that describe the outcome
38- After creating tasks, use TaskUpdate to set up dependencies (blocks/blockedBy) if needed
39- Check TaskList first to avoid creating duplicate tasks
