Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden. 'Trigger' implies an action that initiates something, but it doesn't disclose what happens when triggered (e.g., starts playback, advances to next item, or activates a playlist), whether it's reversible, or any side effects like audio output changes. This leaves significant behavioral gaps for a tool with potential audio system impact.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
