SKILL.md

Skill based on OP Stack specs (ethereum-optimism/specs), generated from sources/optimism. Doc path: sources/optimism/specs/.

The OP Stack is the software stack powering Optimism (OP Mainnet), Base, and other L2s. It defines how the L2 chain is derived from L1, how deposits and withdrawals work, standard predeploys/precompiles, fault proof components, and system configuration. Use this skill when building or debugging L2 nodes, batchers, bridges, withdrawal tooling, or contract integrations.
