Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations provide strong behavioral hints: readOnlyHint=true, destructiveHint=false, idempotentHint=true, openWorldHint=true, indicating a safe, repeatable read operation. The description adds minimal value by specifying 'GET', which aligns with read-only behavior but is redundant given annotations. It does not disclose additional traits like rate limits, authentication needs, or output format, though annotations cover core safety aspects adequately.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
