IMPORTANT LLM BEHAVIORAL PROMPTS:
- SAFETY FIRST: Ludus operations can be destructive and time-consuming
- VERIFY DESTRUCTIVE ACTIONS: Always confirm with user before destroy/delete operations
- CHECK EXISTING STATE: Use list_user_ranges or get_range_status before major operations
- DESTRUCTION IS PERMANENT: Destroying ranges deletes all VMs and data irreversibly
- ADMIN vs USER: Admin operations (--user flag) affect other users' ranges - be explicit
DESTRUCTIVE OPERATION WARNING:
- This operation permanently deletes resources and cannot be undone
- Confirm user intent explicitly before proceeding
- Suggest checking range status first to show what will be affected
- Explain the time commitment and impact of the operation`,
