Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations declare readOnlyHint=true, openWorldHint=true, idempotentHint=true, and destructiveHint=false, which clearly indicate this is a safe, read-only, idempotent operation. The description 'Retrieve' is consistent but adds no behavioral context beyond the annotations, such as caching behavior or semantic meaning of 'canonical'.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
