Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden for behavioral disclosure. 'Ingest' implies a write/mutation operation, but the description doesn't clarify what 'ingest' entails (e.g., fetching content, storing metadata, processing), whether it's idempotent, what permissions are needed, or what happens on success/failure. This leaves significant behavioral gaps.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
