Skill is based on Arbitrum Nitro (OffchainLabs/nitro), generated from source at the listed date. Main docs live at nitro-docs and developer.arbitrum.io.
Nitro is the current Arbitrum L2 stack: Geth for execution, ArbOS for L2 chain services (bridges, batching, compression), and WASM-based interactive fraud proofs. The Nitro repo contains the node implementation, ADRs, and the BOLD dispute protocol integration; run/build and operator docs are in the external documentation.
