Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the agent knows this is a safe read. The description adds the 'published' nuance, indicating the task returns the public profile summary rather than internal data, but it doesn't describe any additional behavioral traits such as field subsets or edge cases. The description is consistent with the annotations and provides some value beyond them.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
