Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The annotations already declare destructiveHint=true, idempotentHint=true, and readOnlyHint=false, so the safety profile is fully covered by structured data. The description adds almost nothing beyond that: it does not say whether the deposit's associated transaction is also removed, whether the estimate balance is recalculated, or whether the deletion is reversible.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
