Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It mentions 'pagination and filtering' which hints at some behavior, but doesn't describe what the tool returns (e.g., format, structure), whether it's read-only or has side effects, error conditions, rate limits, or authentication requirements. For a tool with 5 parameters and no annotation coverage, this leaves significant behavioral gaps.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
