- Retrieves EVM opcode documentation. Use when implementing, testing, reviewing, or debugging any opcode — including when an opcode is referenced by mnemonic (ADD, PUSH1, RETURN) or by hex byte (01, 60, F3).
- argument-hint:
- HEX or mnemonic, space-separated (e.g., 01 60 RETURN)
- allowed-tools:
- Bash
- If
$ARGUMENTSis empty, report: "Error: Provide one or more opcodes (hex bytes or mnemonics, e.g., 01 60 RETURN)." - Split
$ARGUMENTSon whitespace. For each token: if it is a mnemonic (e.g., ADD, PUSH1, RETURN), convert it to the corresponding hex byte (e.g., ADD→01, PUSH1→60, RETURN→F3). Then run:$SKILL_DIR/scripts/opcode_doc <HEX>. - Use the output to verify stack inputs, stack outputs, gas costs, error cases, and examples.
