TypeScript Advanced Types

What it does

Once installed, the agent gets a reference guide on TypeScript's advanced type system, so when you ask for complex typing it can write generics, conditional types, mapped types, template literal types and utility types with clearer, more type-safe patterns. It includes worked code examples and best-practice notes, and points to a longer companion file for further patterns. It is guidance only: it shapes the code the agent writes rather than running tools.

Try asking

• “Create a generic function that merges two objects and keeps both types in the result”Copy
• “Write a mapped type that makes every property of my Config interface readonly and optional”Copy
• “Build a type that generates getter method names from the keys of my Person interface”Copy
• “Explain how to use conditional types to extract the return type of a function”Copy

Get better results

• Name the TypeScript version and strict-mode settings in your request so the generated types match your compiler.
• Ask the agent to show a type test or run tsc on the result, since the skill itself does not execute checks.
• Start with a concrete example of the data shape you need; the skill works best on specific type problems.
