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, but it only restates the basic action. It doesn't reveal whether the display rate change affects existing keyframes, whether the asset must be saved after, what valid fps ranges exist, or how 'display frame rate' relates to the sequence's time formatting. The term 'display' hints at a specific concept but is never explained.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
