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 what the tool does ('Get account nonce') but lacks behavioral details: it doesn't specify if this is a read-only operation (implied but not explicit), potential errors (e.g., invalid address), rate limits, network calls, or return format. For a tool with zero annotation coverage, this is insufficient disclosure.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
