Propagate Guardian contract changes safely across server, Rust client, TypeScript client, multisig SDKs, examples, docs, and tests. Use when Codex changes `guardian.proto`, HTTP JSON payloads, response shapes, status enums, auth requirements, or any…

Set up and run the end-to-end qualification suite in this repository: the deterministic profile against a provisioned stack, and the live profile driving real Miden transactions from a CI-held treasury. Use when Codex needs to run or debug…

Run, evaluate, and report production GUARDIAN benchmarks with the repository's distributed ECS client harness. Use when Codex needs to prepare benchmark profiles, verify prod benchmark readiness, execute ECDSA/Falcon/mixed gRPC runs against GUARDIAN, clean up…

Drive manual smoke testing of the Rust `miden-multisig-client` SDK in this repository through the interactive `examples/demo` CLI and targeted Rust checks. Use when Codex needs to verify account creation, cosigner sync, proposal creation/sign/execute, offline…

Drive manual smoke testing of the TypeScript `@openzeppelin/miden-multisig-client` SDK in this repository through the browser-only `examples/smoke-web` harness and targeted TypeScript checks. Use when Codex needs to verify browser multisig account creation,…

Implement and debug Guardian authentication and signature flows across server, clients, multisig SDKs, and examples. Use when Codex changes request signing, auth metadata, ack signing, Falcon or ECDSA behavior, key managers, public key handling, or signature…

Identify the impact radius of a proposed or in-progress change in the Guardian repository and turn it into a concrete edit and validation plan. Use when Codex needs to map a request, bug, or diff across server, Rust client, TypeScript client, multisig SDKs,…

Implement, debug, and validate proposal lifecycle changes across the Rust and TypeScript multisig SDKs and their example harnesses. Use when Codex touches proposal creation, listing, signing, readiness, execution, import or export, offline signing, sync…

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…

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…

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…

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…

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…

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…

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…

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,…

Testing conventions for openzeppelin-contracts. Use when writing or modifying tests, mocks, or formal verification specs. Covers hardhat-exposed $-wrappers, when manual mocks are warranted, Hardhat+Chai patterns (loadFixture, shouldBehaveLike, multi-target…

Add a changelog entry for a PR. Use when the user asks for a changeset, when finishing a PR that changes user-visible contract behavior, or when the changeset-bot has flagged the PR. Skip for NatSpec-only edits, internal refactors with no observable effect,…

API design rules for openzeppelin-contracts. Use when adding, modifying, or reviewing any contract under contracts/. Covers virtual, memory vs calldata, public vs external, overloads, no-op vs revert, _update single-override pattern, internal/external split,…

Solidity style and safety conventions for contract source files. Use when writing or editing any .sol file under contracts/. Covers errors, events, NatSpec, imports, file structure, assembly, unchecked, casting, numeric literal formatting, and inheritance…

Add a changeset file for a package version bump

Manage WireMock proxy for RPC testing. Starts the proxy, arms scenarios to simulate transient errors (timeouts, 500s, connection resets, and network-specific errors like Stellar TRY_AGAIN_LATER), and checks metrics. Use to verify relayer behavior under…

Creates commits following the monorepo's Conventional Commits standard with proper GPG signing, scope selection, and pre-commit validation. Reminds about changesets for package changes. Use when creating commits, writing commit messages, or when the user asks…

Use this skill to update the centralized OpenZeppelin docs repo after a smart contracts library changes. Trigger after a contracts release, a merged PR in a contracts library, or any time a docs slice (library + version) needs to be brought back in line with…
