Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden but only states 'analyze' without disclosing behavioral traits like whether it performs calculations, generates reports, requires data inputs, or has side effects. It lacks details on permissions, rate limits, or output format, making it insufficient for a mutation or read operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
