CLI Anything Eth2 Quickstart

DevOps & Security
cli-anything-eth2-quickstart

CLI Anything Eth2 Quickstart is an Agent Skill for devops & security published in the HKUDS/CLI-Anything repository on GitHub: a SKILL.md instruction file an AI agent can load to do this task.

Use eth2-quickstart to autonomously deploy a hardened Ethereum node, install execution and consensus clients, configure validator metadata, expose RPC safely, and inspect node health with structured JSON output.

How to use this skill

Bring this guide into your coding agent with a prompt tailored to the tool you use.

  1. Open your project in Codex.
  2. Copy and paste the prompt below.
  3. Review files and risks before approving any action.
Prompt to paste
Inspect the Agent Skill at https://github.com/HKUDS/CLI-Anything/blob/HEAD/eth2-quickstart/agent-harness/cli_anything/eth2_quickstart/skills/SKILL.md and all supporting files. Report provenance, permissions, scripts, dependencies, and security risks. Propose an exact installation into .agents/skills/cli-anything-eth2-quickstart, but wait for my approval before writing files or running scripts.

Copying this prompt does not install or run the skill. Review third-party files before use.

cli-anything-eth2-quickstart

Agent-native harness for the chimera-defi/eth2-quickstart automation repo. This CLI wraps the repo's canonical shell scripts instead of replacing them.

When To Use

Use this skill when the task involves:

  • bootstrapping a fresh Ethereum node host
  • installing execution and consensus clients with explicit client diversity
  • enabling MEV-Boost or Commit-Boost workflows
  • exposing RPC through Nginx or Caddy
  • updating validator fee recipient or graffiti settings without handling secrets
  • checking machine-readable health with --json

Core Commands

# Canonical machine-readable health
cli-anything-eth2-quickstart --json health-check

# Phase 2 install with explicit client choices
cli-anything-eth2-quickstart --json install-clients \
  --network mainnet \
  --execution-client geth \
  --consensus-client lighthouse \
  --mev mev-boost \
  --confirm

# Guided node setup
cli-anything-eth2-quickstart --json setup-node \
  --phase auto \
  --execution-client geth \
  --consensus-client prysm \
  --mev commit-boost \
  --confirm

# Validator metadata only; no key import
cli-anything-eth2-quickstart --json configure-validator \
  --consensus-client prysm \
  --fee-recipient 0x1111111111111111111111111111111111111111 \
  --graffiti "CLI-Anything"

# Install nginx-backed RPC exposure
cli-anything-eth2-quickstart --json start-rpc \
  --web-stack nginx \
  --server-name rpc.example.org \
  --confirm

Safety Rules

  • Always use --json for agent parsing.
  • Require human confirmation before setup-node, install-clients, or start-rpc.
  • Do not generate validator keys.
  • Do not remove secrets or wallet material.
  • Treat configure-validator as metadata and operator-guidance only.
  • Respect the reboot boundary between Phase 1 and Phase 2.

Runtime Expectations

  • Operates on a local eth2-quickstart checkout.
  • Discovers repo root from --repo-root, ETH2QS_REPO_ROOT, or current working directory.
  • Writes compatible overrides into config/user_config.env when flags map directly to repo settings.
