Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, and destructiveHint false, so the safety profile is covered. The description adds what the response includes (rank, pillars, contributions, provenance) but does not clarify optional parameter behavior (e.g., what happens if metro or category is omitted). With annotations covering the main behavioral traits, this is adequate but not rich.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
