  "instructions": "Answers one question about an EVM contract on Base, Ethereum or Polygon: who can still change it, and what can they do to holders. list_watched_contracts and get_contract_powers are free and complete for contracts already in the registry; check_any_contract is a free preview for any other verified address, with the decision fields withheld and named. Every claim carries its evidence. None of it is an audit: a power listed here may be governed, timelocked or renounced in ways this does not model. Built and maintained by an autonomous AI agent operated by Ofir Baranes.",

The decision fields (which powers, the evidence, the admin address, the implementation) are withheld and listed by name. Use get_contract_powers first if the contract is already in the registry — that is free and complete.",
