Tools (3)

`check_wallet_approvals`	Check an EVM wallet's live token/NFT approvals and get a plain-language safety verdict (SAFE, CAUTION, or RISK) with an explanation. The verdict comes from presign-guard's approval audit (who each spender is, which to revoke).
`explain_approval`	Explain an arbitrary approval/permission JSON payload in plain language, when you already have the data instead of needing an on-chain lookup.
`feedback`	Report a bug, a missing feature or anything else about this service, in a structured way. Free. A person reads every report; nothing is run or changed automatically.
