Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the disclosure burden but provides only one concrete behavioral trait: no streaming. 'Full parity' implies standard OpenAI-compatible request/response behavior, yet auth, rate-limit, error, and side-effect characteristics are not spelled out.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
