Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With annotations declaring readOnlyHint, openWorldHint, and idempotentHint, the description adds valuable context about sources (USPTO/EPO), outputs (patents, ownership status, flagged gaps), and the audit nature. It does not contradict annotations and provides extra detail beyond the structured metadata.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
