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 states this is a 'Get list' operation, implying it's read-only, but doesn't mention any behavioral traits like pagination behavior (though parameters suggest it), rate limits, authentication requirements, or what format the list returns. The description is minimal and lacks important operational context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
