Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations provide clear hints: readOnlyHint=true, destructiveHint=false, idempotentHint=true, openWorldHint=true, indicating a safe, non-destructive, repeatable operation with open-world semantics. The description adds minimal context by specifying 'GET', which aligns with read-only behavior, but does not disclose additional traits like authentication requirements, rate limits, or what data is returned. Since annotations cover the safety profile adequately, the description's limited addition warrants a baseline score.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
