dune

Expert assistant for querying and analyzing on-chain blockchain data using Dune Analytics. Use whenever the user wants to: analyze blockchain/on-chain data, write SQL for Dune, find wallet activity, track DeFi protocol metrics, analyze NFT trades, monitor token transfers, investigate smart contract events, check token prices on-chain, find top holders, measure DEX volume, or explore any crypto/web3 data. Trigger even if the user doesn't mention "Dune" explicitly — if they want blockchain data insights or on-chain analysis, this skill applies. Also trigger when the user provides a contract address and wants data for it. Enforces credit budget rules (500 warn / 700 block) and free-vs-paid key separation.
