Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full behavioral disclosure responsibility. It mentions the tool returns a public inventory, implying no authentication, but does not disclose potential response format, pagination, rate limits, or what 'sections' means in practice. This is minimal behavioral context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
