What is openzeppelin-skills?

OpenZeppelin Skills gives AI coding assistants like Claude a set of specialized "skills" for building and auditing smart contracts. Instead of relying on the AI's general programming knowledge, these skills teach it the specific best practices, setup steps, and security standards for OpenZeppelin's widely trusted contract libraries. The result is an AI that helps you write safer blockchain code from the start. The project works by installing small instruction modules that Claude can reference when you ask it to help with a blockchain project. Once installed, the skills cover two main jobs. First, they can scaffold a new project for several blockchain platforms, including Solidity (Ethereum), Cairo (Starknet), Stylus, Stellar, and Sui Move. Second, they guide the AI through upgrading existing contracts and reviewing Sui Move code for security issues. The main development skill also ties into a command-line tool that generates reference implementations, giving the AI a concrete example of best practices to follow. This tool is for developers, founders, or technical PMs who are building decentralized applications and want to use AI to speed up their workflow without sacrificing security. For example, if you are launching a token on Ethereum, you could use this to have Claude safely scaffold a Solidity project using OpenZeppelin's audited standards. If you are expanding to a newer network like Sui or Starknet, the skills ensure your AI helper knows the correct setup and upgrade procedures for those specific platforms rather than guessing. The project is notably platform-agnostic for the blockchain space, supporting five different blockchain ecosystems out of the box. It also offers flexible installation options, meaning you can plug it directly into Claude Code as a plugin or manually copy the skill files into your local AI assistant configuration. The README doesn't go into deep detail on exactly what each setup or upgrade skill does, but the structure makes clear that it functions as a guided, security-focused checklist for AI agents.
