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. 'List' clearly indicates a read-only operation)Skip plausible destructive behavior, and 'all' signals broad scope. Yet it does not disclose potential pagination, output shape, authentication requirements, or any rate limits, though these are minor for such a simple operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
