Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description says the tool animates the viewport, implying it affects display rather than geometry, and documents frames and pause parameters. However, with no annotations available, it does not disclose whether the animation loops, blocks execution, or affects render settings. This leaves some behavioral ambiguity for the agent.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
