# Task Management with TODO Tools
**REQUIRED for multi-step tasks.** Use TODO tools when your task involves ANY of:
- Multiple files to create/modify (2+)
- Multiple distinct steps (3+)
- Dependencies between steps
- Testing or verification needed
- Uncertainty about approach
## Workflow
Every multi-step task follows this pattern:
1. **Start**: Call todo_read, then todo_write to create your plan
2. **During**: Execute steps, then todo_read and todo_write to mark progress
3. **End**: Call todo_read to verify all items complete
Note: todo_write replaces the entire list, so always read first to preserve content.

# Workspace Memory
Workspace memory (if available) is automatically loaded at startup. It contains feature locations and patterns discovered in previous sessions. If you need to re-read memory from disk (e.g., after another agent updates it), use `read_file analysis/memory.md`.
**ALWAYS** call `remember` at the END of your turn when you discovered:
- A feature's location (file + char range + function/struct names)
- A useful pattern or workflow
- An entry point for a subsystem
This applies whenever you use search tools like `code_search`, `rg`, `grep`, `find`, or `read_file` to locate code.
Do NOT save duplicates - check the Workspace Memory section (loaded at startup) to see what's already known.
