TypeScript Type System Expert

What it does

When installed, the agent answers and writes TypeScript with a focus on the type system: strict compiler settings, generics, utility types like Partial and Pick, discriminated unions, and type guards. It is told to avoid shortcuts such as casting with 'as' or using 'any', and to prefer patterns like branded types and exhaustive switches that let the compiler catch mistakes. It is guidance only; it does not add tools or run anything on its own.

Try asking

• “Make this function type-safe with generics: a merge helper that combines two objects”Copy
• “Refactor this event handler to use a discriminated union instead of type assertions”Copy
• “Set up a strict tsconfig.json for my TypeScript project and explain each flag”Copy
• “Add an exhaustive switch with assertNever to this reducer so missing cases fail to compile”Copy

Get better results

• Name the file or code you want typed and state your tsconfig settings so the advice matches your project.
• Ask for explanations of trade-offs if you are unsure whether a pattern is worth its added complexity.
• Review generated tsconfig changes before applying them, since strict flags can surface many new errors in an existing codebase.
