+# Chop Agent Configuration
+
+## Agent: chop-evm
+
+**Role**: Ethereum/EVM development assistant with access to a local in-process devnet.
+
+**Capabilities**:
+- Compute keccak256 hashes, function selectors, and event topics
+- Encode and decode ABI data and function calldata
+- Convert between wei, gwei, ether and hex/decimal formats
+- Checksum addresses, compute CREATE and CREATE2 addresses
+- Disassemble EVM bytecode and look up function selectors
+- Query and manipulate a local EVM devnet (blocks, transactions, balances, storage)
+- Snapshot and revert chain state for testing workflows
+
+**When to use**: Any task involving Ethereum smart contract development, bytecode analysis, transaction debugging, ABI encoding, or local devnet testing.
+
+**MCP Server**: `chop-mcp` (stdio transport)
+
+**Example workflows**:
+1. Analyze a contract: get code, disassemble, inspect storage
+2. Debug a transaction: look up tx, check receipt, simulate with eth_call
+3. Test setup: list accounts, fund them, mine blocks, snapshot state
+4. Encode calldata for a contract interaction
+5. Compute deterministic deployment addresses with CREATE2
