Firebase development guidelines for Firestore, Authentication, Functions, and Storage with TypeScript and Angular.
Configure and build Model Context Protocol (MCP) servers for Claude Code integration. Set up database, filesystem, git, and API connections. Build custom MCP servers with TypeScript/Python SDK, implement tools and resources, configure transports (stdio, HTTP), and deploy for production.
Jotai状態管理ライブラリのエキスパートスキル。Reactアプリケーションでのatomベースの状態管理を実装する際に使用。以下の場合にこのスキルを使用: (1) Jotaiのatom設計・実装 (2) 派生atom、非同期atom、atomFamilyの実装 (3) Jotaiのベストプラクティスに基づくリファクタリング (4) パフォーマンス最適化（selectAtom、splitAtom等） (5) 永続化（localStorage/sessionStorage連携） (6) TypeScript型定義 (7) テスト実装 ユーザーが「Jotai」「atom」「状態管理」に関する質問や実装依頼をした場合に発動。
Provides domain-specific best practices for Node.js development with TypeScript, covering type stripping, async patterns, error handling, streams, modules, testing, performance, caching, logging, and more. Use when setting up Node.js projects with native TypeScript support, configuring type stripping (--experimental-strip-types), writing Node 22+ TypeScript without a build step, or when the user mentions 'native TypeScript in Node', 'strip types', 'Node 22 TypeScript', '.ts files without compilation', 'ts-node alternative', or needs guidance on error handling, graceful shutdown, flaky tests, profiling, or environment configuration in Node.js. Helps configure tsconfig.json for type stripping, set up package.json scripts, handle module resolution and import extensions, and apply robust patterns across the full Node.js stack.
Production Fastify (TypeScript) patterns: schema validation, plugins, typed routes, error handling, security hardening, logging, testing with inject, and graceful shutdown
Expert in Jest testing framework, advanced mocking strategies, snapshot testing, async patterns, TypeScript integration, and performance optimization
Sanity CMS development guidelines for schema creation, GROQ queries, TypeScript integration, and project organization
Initialize a new Bun project with TypeScript and optimal configuration. Use when starting a new Bun project or converting a directory to a Bun project.
React/TypeScript frontend implementation patterns. Use during the implementation phase when creating or modifying React components, custom hooks, pages, data fetching logic with TanStack Query, forms, or routing. Covers component structure, hooks rules, custom hook design (useAuth, useDebounce, usePagination), TypeScript strict-mode conventions, form handling, accessibility requirements, and project structure. Does NOT cover testing (use react-testing-patterns), E2E testing (use e2e-testing), or deployment.
Expert guidance for Jotai state management in React applications. Provides best practices, performance optimization, and architectural patterns. Use when designing atom structures, implementing state management, optimizing re-renders, handling async state, integrating with TypeScript, or reviewing Jotai code for performance issues. Triggers on tasks involving Jotai atoms, derived state, focusAtom, splitAtom, atomFamily, or state management architecture decisions.
Helps create XState v5 state machines in TypeScript and React. Use when building state machines, actors, statecharts, finite state logic, actor systems, or integrating XState with React/Vue/Svelte components.
Guide for building MCP (Model Context Protocol) servers that integrate external APIs/services with LLMs. Covers Python (FastMCP) and TypeScript (MCP SDK) implementations.
