Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure. It states 'Execute multiple API queries simultaneously', implying a write or action operation, but doesn't specify if it's read-only, destructive, requires authentication, has rate limits, or what the output looks like. For a tool with no annotations, this is a significant gap in transparency about its behavior and constraints.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
