What changed: TodoWrite tool now controlled by runtime feature flag instead of hardcoded visibility Previous behavior: TodoWrite had hardcoded visibility conditions New behavior: Todo list visibility controlled by todoFeatureEnabled feature flag (defaults to disabled) Implementation: Tool inclusion controlled by dynamic feature flag system rather than hardcoded conditions Impact:
- Todos become opt-in feature rather than always-on
- Tool functionality remains fully implemented but filtered out at runtime by default
- Users must explicitly enable todo feature to see todo list management
- Creates configurable task management system
- Todos still persist to disk and function when enabled
