Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden of behavioral disclosure. It only states that details are returned, but does not mention read-only nature, authentication requirements, rate limits, or whether the call is safe. The verb 'Get' implies idempotency, but explicit safety cues are missing.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
