Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full responsibility for disclosing behavioral traits, but it only states the search action. It does not mention read-only nature, authentication requirements (the API key is only in the schema), output format, pagination, error handling, or any side effects. This is a significant gap for an agent assessing safety and expected behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
