Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The annotations already establish that this is a read-only, idempotent, non-destructive open-world operation. The description adds useful behavioral context by specifying that only metadata/approved fields are returned and that secrets, contacts, and original files are excluded.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
