Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, and destructiveHint, so the safety profile is clear. The description adds the scope of 'tracked companies' and the available filter dimensions, but does not disclose behavior such as result limits, pagination, or how verified_only affects results. With annotations covering safety, the added behavioral context is modest.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
