Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It names the subject (Monad EVM metrics, JSON-RPC latency) but does not state whether the operation is read-only, what happens on invalid input, any rate limits, or whether results are historical or real-time. Without annotations, this is a significant gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
