Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure. While 'Mute or unmute' implies a state-changing operation, the description doesn't address important behavioral aspects: whether this requires specific permissions, what happens to audio signals when muted, whether changes are immediate or require confirmation, or what feedback (if any) the tool provides. For a mutation tool with zero annotation coverage, this is a significant gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
