WHY IT NEEDS A POLICY

Why addClozeCard needs a policy

This tool creates a new cloze deletion card in an Anki deck. Creating data is a Write operation. Severity is low because: (1) the action is reversible—cards can be deleted; (2) the blast radius is limited to flashcard study material with no external consequences; (3) misuse would only affect the user's own Anki learning system. The tool does not execute code, modify financial systems, or permanently destroy data.

From the tool's definition Tool name 'addClozeCard' and description 'Add a cloze deletion card to a deck' indicate creation of new flashcard data.
