What it does

This skill provides expert assistance with TypeScript type definitions. It can generate, explain, and debug complex types, ensuring code correctness and maintainability. The skill specializes in creating interfaces, type aliases, generics, and utility types to improve developer productivity.

When to use it

• Generating Interfaces: You need a new interface for a data structure but are unsure of the correct typing.
• Understanding Complex Types: Existing TypeScript code uses advanced type constructs you don't fully understand.
• Debugging Type Errors: You’re encountering frustrating type errors and need help identifying the root cause.
• Refactoring Code: You want to improve the type safety of an existing codebase by adding or refining types.

Key capabilities

• Generates TypeScript interfaces and type aliases.
• Explains complex TypeScript type definitions.
• Debugs TypeScript type errors.
• Provides guidance on using generics and utility types.

Example prompts

• "Create a TypeScript interface for a 'Product' object with properties: name (string), price (number), and inStock (boolean)."
• "Explain this TypeScript code: type Result<T, E> = { success: true; value: T } | { success: false; error: E }."
• “I’m getting a type error saying 'Property 'x' does not exist on type 'y''. Can you help me debug it?"

Tips & gotchas

The skill requires familiarity with basic TypeScript syntax. Providing clear and concise descriptions of the desired types will yield more accurate results.
