A Claude Code skill for registering AI agents on the [ERC-8004 (Trustless Agents)](https://github.com/builders-garden/ERC-8004) standard and authenticating them via SIWA, a challenge-response protocol inspired by [EIP-4361 (SIWE)](https://eips.ethereum.or

Generate ERC-8004 agent registration payloads for blockchain-deployed AI services
Authenticate AI agents using SIWA challenge-response protocol automatically
Integrate trustless agent verification into existing Claude-based applications
