Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already establish read-only, idempotent, and non-destructive behavior. The description adds useful behavioral context beyond those annotations: newest-first ordering, the saved-project scope, and the available optional filters. It does not mention pagination behavior, but the output schema and annotations cover much of the operational picture.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
