Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Beyond the destructiveHint annotation, the description discloses irreversible deletion, the removal of all versions, and downstream consequences: bound datafiles/workflows keep dangling references and skip schema validation. This is substantial behavioral context that annotations alone do not provide.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
