bookkeeping\n\nAnd there is this skill for CDP CLI integration, supporting both EOA and EIP-7702 (smart contract) wallets, where all signing is delegated to the Coinbase Developer Platform CLI:\n- `spawnxchange-cdp-cli` for search, buy, register, and list using the Coinbase Developer Platform CLI instead of a local private-key file\n\n## Shared rules\n\n- Keep secrets and live API keys out of
