Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full responsibility for behavioral disclosure. It only mentions the encoding pipeline and does not address side effects, resource requirements (e.g., microphone access), read-only nature, or output details. This is insufficient for safe and effective tool use.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
