Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and destructiveHint=false, covering safety and side-effect behavior. The description adds 'random' as a behavioral trait and mentions the content type, but does not disclose additional details like rate limits or pagination. This is acceptable given annotation coverage, so a baseline 3 applies.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
