WHY IT NEEDS A POLICY

Why create_cards_bulk needs a policy

This tool creates flashcard data through the Mochi API. While it modifies state by adding records, the operation is reversible via delete_card or similar mechanisms. The blast radius is moderate: an AI could flood the system with spam cards or create thousands of unwanted records, but no data is permanently destroyed and no financial transactions occur.

From the tool's definition Tool name 'create_cards_bulk' and description 'Create multiple flashcards at once' indicate data creation. The bulk operation affects multiple records but is reversible (cards can be deleted, content modified).
