복잡한 제네릭 타입을 설계하고, `any` 타입을 엄격한 대안으로 리팩토링하며, 타입 가드와 유틸리티 타입을 생성하고 TypeScript 컴파일러 오류를 해결합니다.
mcollina/typescript-magician은 TypeScript 개발자를 위한 전문화된 AI 에이전트 스킬입니다. 이 스킬은 복잡한 제네릭 타입, 조건부 타입, 매핑된 타입, 템플릿 리터럴 타입 등의 고급 타입 시스템 기능을 설계하고 구현하는 데 특화되어 있습니다. 또한 `any` 타입을 엄격한 타입으로 리팩토링하고, 사용자 정의 타입 가드와 유틸리티 타입을 생성하며, TypeScript 컴파일러 오류를 진단하고 해결합니다. 이 스킬은 Claude Code, Cursor, Codex와 같은 주요 AI 에이전트 플랫폼에서 사용할 수 있으며, 개발자가 TypeScript의 타입 시스템을 최대한 활용하여 더 안전하고 유지보수 가능한 코드를 작성할 수 있도록 지원합니다. `infer`, `extends`, `Partial`, `Record`, `ReturnType`, `Awaited`와 같은 키워드 및 유틸리티 타입과 관련된 질문에 특히 효과적입니다.

This repo contains 4 individual skills — each has its own dedicated page.
Creates, structures, and reviews technical documentation following the Diátaxis framework (tutorials, how-to guides, reference, and explanation pages). Use when a user needs to write or reorganize docs, structure a tutorial vs. a how-to guide, build reference docs or API documentation, create explanation pages, choose between Diátaxis documentation types, or improve existing documentation structure. Trigger terms include: documentation structure, Diátaxis, tutorials vs how-to guides, organize docs, user guide, reference docs, technical writing.
Guides development of Fastify Node.js backend servers and REST APIs using TypeScript or JavaScript. Use when building, configuring, or debugging a Fastify application — including defining routes, implementing plugins, setting up JSON Schema validation, handling errors, optimising performance, managing authentication, configuring CORS and security headers, integrating databases, working with WebSockets, and deploying to production. Covers the full Fastify request lifecycle (hooks, serialization, logging with Pino) and TypeScript integration via strip types. Trigger terms: Fastify, Node.js server, REST API, API routes, backend framework, fastify.config, server.ts, app.ts.
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.
Debugs native module crashes, optimizes V8 performance, configures node-gyp builds, writes N-API/node-addon-api bindings, and diagnoses libuv event loop issues in Node.js. Use when working with C++ addons, native modules, binding.gyp, node-gyp errors, segfaults, memory leaks in native code, V8 optimization/deoptimization, libuv thread pool tuning, N-API or NAN bindings, build system failures, or any Node.js internals below the JavaScript layer.
ElevenLabs text-to-speech with mac-style say UX.
Oracle CLI second-model review/debug/refactor/design with selected files, dry-run token checks, API or browser engine.
Capture and automate macOS UI with the Peekaboo CLI.
Generate multiple radically different interface designs for a module using parallel sub-agents. Use when user wants to design an API, explore interface options, compare module shapes, or mentions "design it twice".
Build a throwaway prototype to flesh out a design — a runnable terminal app for state/business-logic questions, or several radically different UI variations toggleable from one route.
Interview the user relentlessly about a plan or design until reaching shared understanding, resolving each branch of the decision tree. Use when user wants to stress-test a plan, get grilled on their design, or mentions "grill me".
