Manage local development networks (devnets) for lean consensus multi-client testing. This skill should be used when the user asks to run a devnet, start or stop devnet nodes, spin up a local testnet, configure validator nodes, regenerate genesis files, change Docker image tags, collect or dump node logs, troubleshoot devnet issues, restart a node with checkpoint sync, run a long-lived devnet with detached containers, or perform rolling restarts to upgrade images.

Review and analyze devnet run results. Use when users want to (1) Analyze devnet logs for errors and warnings, (2) Generate a summary of a devnet run, (3) Identify interoperability issues between clients, (4) Understand consensus progress and block production, (5) Debug forks and finalization issues.

Test ethlambda PR changes in multi-client devnet. Use when users want to (1) Test a branch/PR with other Lean clients, (2) Validate BlocksByRoot or P2P protocol changes, (3) Test sync recovery with pause/unpause, (4) Verify cross-client interoperability, (5) Run integration tests before merging.

Expert knowledge for using the eth-agent library - the simplest, safest way for AI agents to send stablecoins on Ethereum. Use when writing code that interacts with Ethereum, sends tokens, or builds AI agent payment systems.

Operate, inspect, monitor, and debug ethrex EL nodes on ethpandaops devnets (status sweeps, peers/logs, blob & fork tracking, Hive results, wipe/resync, incident history). Use whenever the user asks to check/inspect a devnet node, ssh into one, read logs, investigate a devnet error, track blob inclusion or fork schedule, see Hive conformance, deploy/wipe a node, or ask about past devnet problems.
