Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden of behavioral disclosure. It only says 'Returns', which is mildly read-only, but it does not explain how detail_level alters the output, what happens when no robot_name is provided, or how robot_name and robot_names interact. The phrase 'summary and parameter details' may even mislead when detail_level is set to 'examples'.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
