Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The annotations already disclose read-only, idempotent, non-destructive behavior. The description adds the qualifier 'lightweight', which hints at a reduced payload but does not elaborate on response structure or any side effects. No contradiction exists, but the description contributes minimal behavioral insight beyond the annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
