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. The verb 'Register' implies a write operation, but there is no detail on side effects (e.g., whether a new record is created, whether duplicates are rejected), required permissions, or error behavior. The mention of 'with results and evidence' hints at stored data but does not disclose validation or processing semantics.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
