Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden. It states the tool gets 'processing status' but does not disclose possible status values, whether it's read-only, or any other behavioral traits. While adequate for a simple poll, it lacks extra context that would help an agent.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
