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 sets the active scene, implying a mutation, but does not cover critical aspects like permissions required, whether the change is immediate or reversible, error conditions (e.g., invalid scene name), or impact on ongoing streams/recordings. This leaves significant gaps in understanding the tool's behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
