Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations indicate readOnlyHint=false (non-read operation), destructiveHint=false (non-destructive), idempotentHint=false (non-idempotent), and openWorldHint=true (open-world). The description adds no behavioral context beyond these annotations, such as what 'rebuild' entails (e.g., downtime, data persistence, permissions required). With annotations covering basic safety, the description fails to add meaningful value, but does not contradict annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
