Optimism and OP Stack development — deployment, cross-chain messaging (CrossDomainMessenger), SuperchainERC20, predeploy contracts, gas model (L1 data fee + EIP-4844), and Superchain interop.
Optimism is an EVM-equivalent Layer 2 using optimistic rollups. Transactions execute on L2 with data posted to Ethereum L1 for security. The OP Stack is the modular framework powering OP Mainnet, Base, Zora, Mode, and the broader Superchain. Smart contracts deploy identically to Ethereum — no custom compiler, no special opcodes.
--legacy flag, no custom compiler. forge create and hardhat deploy work identically to Ethereum. If someone tells you to change your Solidity for "OP compatibility", they are wrong.eth_estimateGas, your cost estimate will be wrong. The L1 data fee often dominates total cost.

Clear and well structured, with only minor parts that might need a second read.
How directly an agent can act on the SKILL.md instructions, rated from 1 to 5.
Mostly actionable with clear steps; only a few small gaps remain.
