Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden for behavioral disclosure. While 'Get' implies a read-only operation, the description doesn't specify whether this involves network calls, cryptographic computation, rate limits, error conditions, or what format the address will be in. For a cryptographic tool with zero annotation coverage, this minimal description leaves important behavioral aspects undocumented.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
