arbitrum-dapp-skill
High-risk skill: provides guidance and installer scripts to scaffold and deploy Arbitrum dApps (Stylus, Solidity, frontend) and installs into `~/.claude/skills`. It instructs executing a remote installer (`bash <(curl -s https://raw.githubusercontent.com/hummusonrails/arbitrum-dapp-skill/main/install.sh)`), runs `git clone`, posts to `https://arbitrum-dapp-skill.goatcounter.com/api/v0/count`, and requires `PRIVATE_KEY` and other env vars.
