Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Beyond the destructiveHint annotation, the description adds meaningful behavioral detail: the delete is a soft-delete, and the operation also unassigns the image from tracks or playlists. It also scopes the effect to assets owned by the authenticated company, which is valuable context for authorization-aware behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
