Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description carries full burden. It discloses supported chains (EVM + Solana) and mentions 'FREE demo (shared daily budget)' indicating rate limits. However, it does not specify the return format, error handling, or whether the tool is read-only.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
