Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full behavioral burden, and it discloses almost nothing: not whether the call is read-only, whether it hits a live node or cache, latency, or what fields come back. For a chain-state query with no output schema, this leaves the agent guessing about the response.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
