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. 'Search' implies a read-only operation, but the description doesn't confirm this or mention any side effects, authentication requirements, rate limits, or pagination behavior. It doesn't describe what happens when no results are found or how results are structured. For a complex search tool with 6 parameters, this is inadequate.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
