Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the burden of behavioral disclosure. It does disclose the credential requirement, which is useful signal about the tool's environment dependency)Skip. It does not describe the return format, whether the call has side effects, or what happens if credentials are missing, but for a simple listing operation the prerequisite disclosure provides moderate transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
