Crypto Wallet Safety Check — Agent Skill (SKILL.md)

A pre-flight safety check for any wallet before you send funds to it.

A drop-in agent skill (SKILL.md) that teaches your AI agent to check EIP-7702 delegations, token approvals, fresh-wallet status, honeypot behavior, and permit-phishing signatures — using only public RPC endpoints.

WHY IT MATTERS

An EIP-7702-delegated wallet can look completely normal on an explorer. The moment you send ETH to it, the delegate contract forwards it out — sometimes in the same block. A "small test amount" is not safe either: the drainer takes that too. This skill teaches your agent to check the code first, always.

WHAT IT CHECKS

• EIP-7702 delegation — wallets whose incoming funds get forwarded to a drainer automatically

• Approval audit — dangerous allowances to unknown spenders

• Fresh-wallet detection — nonce 0 wallets that never sent a transaction

• Honeypot checks — whether a token can actually be sold, not just bought

• Permit phishing — off-chain signature requests that move funds without a transaction
