95 / 100 · Low risk

Fine to try. Some of what it can do is expected: a devops skill usually runs commands, installs tools and uses cloud credentials.

Ethereum L2 landscape — Arbitrum, Optimism, Base, zkSync, Unichain, Celo. How they work, how to deploy, how to bridge, and which to use when. Includes 2025–2026 updates like Celo migration and Polygon zkEVM shutdown.

Works with any agent that supports SKILL.md skills.

What this skill can do

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'layer-2s' ] || [ -L ~/.agents/skills/'layer-2s' ]; then echo 'A skill folder named layer-2s already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/BankrBot/skills' "$d" && git -C "$d" checkout --quiet 'b440a49efee0c0b4cab6f6967232657a69810858' -- 'ethskills-l2s' && mkdir -p ~/.agents/skills && cp -R "$d"/'ethskills-l2s' ~/.agents/skills/'layer-2s' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'layer-2s' ~/.claude/skills/'layer-2s' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
