Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, destructiveHint=false, idempotentHint=true, and openWorldHint=true, covering the core safety profile. The description adds minimal value by implying this is a GET operation (which aligns with annotations) but doesn't disclose any additional behavioral traits like authentication requirements, rate limits, or what the token is used for. With comprehensive annotations, the bar is lower, but the description could still add more context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
