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 upgrades, or (7) understand upgrade restrictions between OpenZeppelin Contracts major versions.
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.
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.
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 Soroban contracts.
Vendor-overridden Livewire skill
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 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, or (6) test upgrade paths for Cairo contracts.
Neon serverless Postgres with autoscaling, instant database branching, and zero-downtime deployments. Use when building serverless applications, implementing database branching for dev/staging, or deploying with Vercel/Netlify.
Full Sentry SDK setup for Node.js, Bun, and Deno. Use when asked to "add Sentry to Node.js", "add Sentry to Bun", "add Sentry to Deno", "install @sentry/node", "@sentry/bun", or "@sentry/deno", or configure error monitoring, tracing, logging, profiling, metrics, crons, or AI monitoring for server-side JavaScript/TypeScript runtimes.
Creates comprehensive API changelogs documenting breaking changes, deprecations, and migration strategies for API consumers. Use when managing API versions, communicating breaking changes, or creating upgrade guides.
Database sharding for PostgreSQL/MySQL with hash/range/directory strategies. Use for horizontal scaling, multi-tenant isolation, billions of records, or encountering wrong shard keys, hotspots, cross-shard transactions, rebalancing issues.
Implements real-time WebSocket communication with connection management, room-based messaging, and horizontal scaling. Use when building chat systems, live notifications, collaborative tools, or real-time dashboards.
