Claude Code: ask. ### `simulate_base_transaction` - The input addresses people (input.to): what it sends cannot be taken back. Description, as the server wrote it: ```untrusted-server-text FREE, runs locally against Base Mainnet RPC. Dry-run a transaction before sending it: eth_call + eth_estimateGas at the latest block. Predicts whether it will revert and decodes the reason (Error(string), Panic(uint256) codes, custom-error selector, or node rejection such as insufficient funds). Returns { ok, willRevert, revertReason, estimatedGas, returnData }. ``` ## Changes things (18) Creates or changes something that can be changed back. Claude Code: ask. ### `approval_risk` - Nothing in its name or description says what it does, so it is counted as a write.
