Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is established. The description adds that the tool returns workflow expectations including token, status, redemption, and replay, which provides semantic context beyond annotations. However, it does not disclose output format details, error behavior, or what 'agent-native' means operationally—leaving some behavioral traits implicit. No contradiction with annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
