WHY IT NEEDS A POLICY

Why whatsapp_star_message needs a policy

Starring/unstarring a message is a reversible modification that changes only the flag or metadata associated with a message. It is not destructive (no deletion), not financial, not executing code, and not a simple read operation since it modifies state. This clearly falls into the Write category—creating or modifying data reversibly.

From the tool's definition Tool name 'whatsapp_star_message' and description 'Star or unstar a message' indicate toggling a message's starred status, which modifies metadata within WhatsApp without deleting, overwriting core data, or executing external operations.
