Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate read-only, idempotent, open world, and non-destructive. The description adds that results are 'public prospecting clues' and not permissions or inventory guarantees, providing further context. No contradictions. Could mention rate limits or freshness but not necessary.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
