TypeScript

Advanced TypeScript — generics, utility types, discriminated unions, type narrowing, strict configuration, and declaration files.

What is TypeScript?

TypeScript is one of 70 specialized agent skills built into the Multos AI platform. When you describe a task related to languages, this skill activates automatically — bringing domain-specific knowledge about typescript, types, generics, type safety, tsconfig, type narrowing directly into your development workflow.

Goes beyond basic typing — generates discriminated unions, template literal types, conditional types, mapped types, and generic constraints. Knows when to use type vs interface, generates type guards and assertion functions, and implements builder pattern with full type safety.

Key Capabilities

  • ✓Generates complete, working implementations for typescript with proper error handling and edge cases
  • ✓Understands best practices and security patterns specific to languages development
  • ✓Provides step-by-step guidance from setup through production deployment
  • ✓Adapts to your existing codebase — works with any framework, language, or architecture
  • ✓Generates tests alongside implementation code to ensure reliability
  • ✓Specialized knowledge of types patterns, common pitfalls, and optimization techniques

How to Use TypeScript on Multos AI

Example Prompts

  • "Create a type-safe event emitter with autocomplete for event names"
  • "Build a generic API client that infers response types from endpoints"
  • "Add strict TypeScript to my JS project with migration strategy"

Example Output

type ApiRoutes = {
  'GET /users': { response: User[]; query: { page: number } };
  'POST /users': { response: User; body: CreateUserInput };
  'GET /users/:id': { response: User; params: { id: string } };
};

async function api<T extends keyof ApiRoutes>(
  route: T, options: Omit<ApiRoutes[T], 'response'>
): Promise<ApiRoutes[T]['response']> { /* ... */ }

Real-World Use Case

A team migrating a large untyped JS codebase created shared type definitions for their API contract and generic utility types that eliminated repetitive declarations across 200+ files — catching 47 runtime bugs during migration.

Frequently Asked Questions

What is the TypeScript skill in Multos AI?

The TypeScript skill is a specialized AI capability within Multos AI that advanced typescript — generics, utility types, discriminated unions, type narrowing, strict configuration, and declaration files. It activates automatically when your prompt relates to languages tasks, providing expert-level guidance and production-ready code.

Do I need to configure TypeScript manually?

No. Multos AI uses intent detection to activate the TypeScript skill automatically when your request involves typescript. There's no setup, no plugins to install, and no configuration files to manage.

Which AI models work best with TypeScript?

All 33 models on Multos AI can leverage the TypeScript skill. For complex languages tasks, we recommend models with larger context windows like Claude Opus 4.6 (1M tokens) or Gemini 3.1 Pro (1M tokens). For quick iterations, faster models like GPT-5.4 Mini or Claude Haiku 4.5 work well.

Can I use TypeScript with my existing project?

Yes. You can connect your GitHub, GitLab, or Bitbucket repository to Multos AI and the TypeScript skill will work with your existing codebase. It understands your project structure, dependencies, and coding patterns to provide contextual assistance.

Is TypeScript available on the free plan?

Yes, all 70 agent skills including TypeScript are available on every plan. Free users get access to lite-tier models, while paid plans unlock more powerful models for complex languages tasks.
