Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description provides some behavioral context ('assertive playback, overrides lower priorities') but lacks details on side effects, permissions, or whether it interrupts other executors. The return type is mentioned as 'str' but no specifics.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
