Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The annotation already declares readOnlyHint=true, so the read-only safety profile is covered. The description adds useful behavioral context beyond that by specifying the result contents: header fields, parameters, SQL, tables touched, and lint findings. It does not mention behavior for a missing saved query, but that is minor for a read-only retrieval tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
