Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations indicate readOnlyHint=false and destructiveHint=false, so the tool may modify state but not destructively. The description adds that dry_run defaults to true, hinting at safety, but does not explain the effect of setting dry_run to false or other behavioral traits.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
