Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare destructiveHint=true and openWorldHint=false, so the safety profile is covered. The description adds genuinely useful context beyond that: only unclaimed plans are discarded, claimed plans retain recovery references, and already-submitted tasks are unaffected — all non-obvious consequences of the call.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
