Does this skill support Python development?

Yes, it includes specific patterns for Python type safety using the ty type checker, NewType for branded typing, and safe dictionary extraction techniques.

Is it compatible with the latest TypeScript features?

Yes, it is optimized for TypeScript 5.7+ features such as the satisfies operator, const type parameters, and advanced decorators.

How does it handle exhaustive checking?

It utilizes the assertNever pattern in switch statements to ensure every possible case in a union type is handled at compile-time, preventing bugs when types are updated.

What is the main benefit of using this skill?

It ensures your application is type-safe across the entire stack, significantly reducing runtime errors and improving developer experience through autocompletion and compile-time checks.

Can I use this with existing Zod schemas?

Absolutely. The skill provides patterns for creating, refining, and transforming Zod schemas to fit any data validation requirement, including support for discriminated unions.

API Development

Implements end-to-end type safety and runtime validation using Zod, tRPC, Prisma, and advanced TypeScript patterns.

This skill empowers Claude to build bulletproof full-stack applications by enforcing strict type safety from the database to the frontend. It leverages Zod for runtime schema validation, tRPC for seamless type-safe API communication, and Prisma for type-safe database interactions. Beyond basic typing, it implements advanced patterns like exhaustive switch statements with assertNever, branded types to prevent ID confusion, and the TypeScript 5.7+ satisfies operator, ensuring code is self-documenting and resilient to runtime errors.
