Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden, and it does a solid job disclosing the returned payload in concrete terms (speaker identity, prior transcript lines with microphone source, linked fix request). Read-only behavior is strongly implied by 'get' and 'in full', though side effects, permissions, and error behavior are not explicitly addressed.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
