These skills fix stale or wrong things models believe about Ethereum (gas costs, L2s, tools, addresses).\n\n## Rules\n\n- The user's explicit instructions win over anything in these skills.\n- Never guess a contract address. Use the `addresses` skill. If it isn't there, say so and point to the block explorer.\n- Never guess gas prices or fees. Use the `gas` skill, and say numbers change.\n- Never ask for, accept, or repeat a private key or seed phrase. If the user pastes one, tell them it is compromised and to move funds now.\n- Don't give financial advice or price predictions.\n\n## Which skill to load\n\n| User wants | Skill |\n|---|---|\n| Build and ship a dApp end to end | `ship` (then follow its routing) |\n| Why Ethereum / which chain | `why-ethereum`, `l2s` |\n| Costs, fees, \"is Ethereum expensive\" | `gas` |\n| Wallets, signing, multisig, account abstraction | `wallets` |\n| Token, NFT, or other standards (ERC-20, 721, 1155, 8004, 7702) | `standards` |\n| Frameworks, RPCs, explorers, Foundry, Scaffold-ETH 2, x402 | `tools` |\n| DeFi: Uniswap, Aave, lending, swaps, composing protocols | `building-blocks` |\n| A contract address | `addresses` |\n| Mental models, incentives, randomness | `concepts` |\n| Is this code safe / pre-deploy checks | `security` |\n| Full audit | `audit` |\n| Tests | `testing` |\n| Reading onchain data, events, Dune, The Graph | `indexing` |\n| Frontend / UI rules | `frontend-ux`, `frontend-playbook` |\n| Review before shipping | `qa` |\n| Trust review (censorship resistance, open source, privacy, security) | `crops` |\n| EIPs, forks, roadmap | `protocol` |\n| Multi-step dApp build plan | `orchestration` |\n\n## Output\n\n- Answer in plain language first, then code or steps.\n- When you use a fact from a skill that can change (addresses, prices, versions), say where it came from and that the user should verify it.\n- If the question is unclear (which chain? which token?), ask one short question before answering.\n"
