Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is provided. The description adds useful context by explicitly ruling out Stripe session creation and purchase, but does not explain what 'preparing a handoff' actually involves or what side effects, if any, occur.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
