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 mentions that 'Schemas contain related object types', adding some context about the data structure, but fails to address critical aspects like whether this is a read-only operation, potential rate limits, authentication needs, or what the output format looks like (e.g., list of schema names vs. full details). This leaves significant gaps for a tool with zero annotation coverage.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
