Install

Skills CLI

npx skills add OpenZeppelin/openzeppelin-skills

Asks which skills and agents to install. Just one: npx skills add OpenZeppelin/openzeppelin-skills --skill develop-secure-contracts — add -g for every project.

Claude Code

git clone https://github.com/OpenZeppelin/openzeppelin-skillscp -r "openzeppelin-skills/skills/develop-secure-contracts" ~/.claude/skills/

Copies the develop-secure-contracts skill into ~/.claude/skills/ for every project (use .claude/skills/ for one project). Repeat for the other skills listed below.

Plugin

/plugin marketplace add OpenZeppelin/openzeppelin-skills

Run inside Claude Code if the repository ships a plugin marketplace, then pick plugins from /plugin.

Skills can run code on your machine — read the SKILL.md first.

What it does

In the author's own words, from each skill's SKILL.md.

  • develop-secure-contracts

    Develop secure smart contracts using OpenZeppelin Contracts libraries. Use when users need to integrate OpenZeppelin library components — including token standards (ERC20, ERC721, ERC1155), access control (Ownable, AccessControl, AccessManager), security primitives (Pausable, ReentrancyGuard), governance (Governor, timelocks), or accounts (multisig, account abstraction) — into existing or new con…

  • review-sui-contracts

    Review Sui Move code that integrates OpenZeppelin Contracts for Sui against the library's own patterns and conventions. Use this when a developer wants their integration checked before shipping. Triggers: "review my Sui Move code", "am I using OpenZeppelin correctly", "check this integration", "is this idiomatic", "review before audit". Checks correct use of OZ primitives, deviations from example…

  • setup-cairo-contracts

    Set up a Cairo smart contract project with OpenZeppelin Contracts for Cairo on Starknet. Use when users need to: (1) create a new Scarb/Starknet project, (2) add OpenZeppelin Contracts for Cairo dependencies to Scarb.toml, (3) configure individual or umbrella OpenZeppelin packages, or (4) understand Cairo import conventions and component patterns for OpenZeppelin.

  • setup-solidity-contracts

    Set up a Solidity smart contract project with OpenZeppelin Contracts. Use when users need to: (1) create a new Hardhat or Foundry project, (2) install OpenZeppelin Contracts dependencies for Solidity, (3) configure remappings for Foundry, or (4) understand Solidity import conventions for OpenZeppelin.

  • setup-stellar-contracts

    Set up a Stellar/Soroban smart contract project with OpenZeppelin Contracts for Stellar. Use when users need to: (1) install Stellar CLI and Rust toolchain for Soroban, (2) create a new Soroban project, (3) add OpenZeppelin Stellar dependencies to Cargo.toml, or (4) understand Soroban import conventions and contract patterns for OpenZeppelin.

  • setup-stylus-contracts

    Set up a Stylus smart contract project with OpenZeppelin Contracts for Stylus on Arbitrum. Use when users need to: (1) install Rust toolchain and WASM target for Stylus, (2) create a new Cargo Stylus project, (3) add OpenZeppelin Stylus dependencies to Cargo.toml, or (4) understand Stylus import conventions and storage patterns for OpenZeppelin.

  • setup-sui-contracts

    Set up a Sui Move smart contract project with OpenZeppelin Contracts for Sui. Use when users need to: (1) install the Sui CLI and Move toolchain, (2) create a new Sui Move package, (3) discover and add OpenZeppelin Sui dependencies to Move.toml via the Move Registry (MVR), (4) learn the integration pattern from the library's examples and API docs before implementing, or (5) understand Sui Move im…

  • upgrade-cairo-contracts

    Upgrade Cairo smart contracts using OpenZeppelin's UpgradeableComponent on Starknet. Use when users need to: (1) make Cairo contracts upgradeable via replace_class_syscall, (2) integrate the OpenZeppelin UpgradeableComponent, (3) understand Starknet's class-based upgrade model vs EVM proxy patterns, (4) ensure storage compatibility across upgrades, (5) guard upgrade functions with access control,…

  • upgrade-solidity-contracts

    Upgrade Solidity smart contracts using OpenZeppelin proxy patterns. Use when users need to: (1) make contracts upgradeable with UUPS, Transparent, or Beacon proxies, (2) write initializers instead of constructors, (3) use the Hardhat or Foundry upgrades plugins, (4) understand storage layout rules and ERC-7201 namespaced storage, (5) validate upgrade safety, (6) manage proxy deployments and upgra…

  • upgrade-stellar-contracts

    Upgrade Stellar/Soroban smart contracts using OpenZeppelin's upgradeable module. Use when users need to: (1) make Soroban contracts upgradeable via native WASM replacement, (2) use Upgradeable or UpgradeableMigratable derive macros, (3) implement atomic upgrade-and-migrate patterns with an Upgrader contract, (4) ensure storage key compatibility across upgrades, or (5) test upgrade paths for Sorob…

  • upgrade-stylus-contracts

    Upgrade Stylus smart contracts using OpenZeppelin proxy patterns on Arbitrum. Use when users need to: (1) make Stylus Rust contracts upgradeable with UUPS or Beacon proxies, (2) understand Stylus-specific proxy mechanics (logic_flag, WASM reactivation), (3) integrate UUPSUpgradeable with access control, (4) ensure storage compatibility across upgrades, or (5) test upgrade paths for Stylus contrac…

Review before you install

A skill is a set of instructions and scripts your agent will follow, and it can run code on your machine. Read the SKILL.md and any scripts first — this listing is not a security review.
