ChainSafe

Run Ethereum multi-client devnets using Kurtosis and the ethpandaops/ethereum-package. Use for spinning up local testnets, validating cross-client interop, testing fork transitions, running assertoor checks, debugging CL/EL client interactions, or verifying new feature implementations across multiple consensus and execution clients.

Debug Lodestar beacon node issues by running a local mainnet node with checkpoint sync and engineMock. Use for investigating networking bugs, peer discovery issues, identify failures, metrics anomalies, or any behavior that needs real-world peer interactions without a full execution client.

Write Lodestar release notes and Discord announcements for new versions. Use when cutting a new release, drafting announcement text, or updating the GitHub release body. Covers header text, Discord announcement, and changelog formatting. Requires access to the Lodestar repo and GitHub CLI for changelog generation.

Use when comparing Ethereum consensus client implementations, looking up how a specific client implements a spec feature, checking client activity (PRs, issues, releases), or understanding architectural differences between Lodestar, Lighthouse, Prysm, Teku, Nimbus, and Grandine.

Search the Ethereum R&D Discord Archive for protocol discussions. Use when looking up what was discussed about a specific topic (ePBS, PeerDAS, inclusion lists, etc.), finding decisions made in Eth R&D Discord, or tracking research conversations. Requires a local clone of ethereum/eth-rnd-archive.

Use when working on Ethereum protocol development, consensus layer, execution layer, beacon chain, EIPs, networking, or any Ethereum R&D topic. Provides reference lookup across specs, APIs, research forums, and governance resources.
