WHY IT NEEDS A POLICY

Why save_draft needs a policy

This tool modifies persistent state by writing draft data to Firebase. It is clearly a Write operation (creates/updates data reversibly) rather than Read (no querying), Execute (no command execution with side effects), Destructive (the save is reversible), or Financial.

From the tool's definition Tool description states 'Save the current draft to Firebase', which creates or persists data reversibly in cloud storage. The operation is a write that can be undone (draft can be overwritten or deleted).
