Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare destructiveHint=true, readOnlyHint=false, and idempotentHint=false, so the mutation profile is covered. The description adds genuinely new behavioral context: only the caller's own dispute is withdrawn, other participants' holds persist, cleanup resumes, and canonical outcomes are unaffected — precisely the effect scope an agent needs for a destructive call.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
