Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden for behavioral disclosure. It only states what the tool does at a high level, without mentioning pagination behavior (implied by skip/limit parameters), rate limits, authentication requirements, error conditions, or what format the results will be in. For a search tool with 3 parameters, this leaves significant behavioral aspects undocumented.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
