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 the tool 'shows' information, implying a read-only operation, but doesn't clarify if it requires authentication, has rate limits, or what happens if no profile is active. For a tool with zero annotation coverage, this is a significant gap in transparency, as it lacks details on permissions, errors, or response format.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
