Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It indicates a write operation ('Persist') and mentions authentication context, but it does not explain side effects (e.g., whether queued outcomes are cleared), idempotency behavior, failure semantics, or authorization requirements. This leaves significant behavioral ambiguity.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
