Rule-based read-only agent for American Bully ($BULLY) on Robinhood Chain. The official $BULLY contract is 0xff0fa3799686ac47e3aff62aa2210a8441737cc3 (chain ID 4663). It answers questions about $BULLY from the project's own press kit and reads on-chain facts for any contract address you send (name, symbol, supply, whether code exists, proxy pattern, match with the official $BULLY contract). It is not an LLM. Market figures, when shown, come from third-party APIs and are labelled as unverified. It gives no trading advice and no safety verdicts.
