Does this skill allow the use of the 'any' type?

No, this skill strictly prohibits 'any'. It guides the AI to use 'unknown' for truly unknown inputs or generics for flexible, reusable logic, ensuring the codebase remains type-safe.

Why are flat interfaces required by this skill?

Flat interfaces ensure that nested objects are defined as dedicated interfaces rather than inline. This improves code readability, makes types easier to extend or reuse, and prevents deeply nested type complexity.

Which TypeScript utility types are supported?

It supports and optimizes all major utility types including Pick, Omit, Partial, Required, Readonly, Record, Extract, Exclude, NonNullable, ReturnType, and Parameters.

How does this skill handle TypeScript enums and unions?

The skill utilizes the 'Const Types' pattern, creating a const object and extracting the type from it. This provides a single source of truth, better runtime value access, and superior autocompletion compared to standard union types.

Herramientas para Desarrolladores

Enforces strict TypeScript standards and advanced architectural patterns to ensure type safety and code maintainability.

This skill empowers Claude to write high-quality, production-ready TypeScript code by adhering to industry-leading strict architectural patterns. It prioritizes the 'Const Types' pattern over traditional unions for a single source of truth, mandates flat interface structures for better readability, and strictly prohibits the use of 'any' in favor of safer alternatives like 'unknown' or generics. By integrating these best practices, the skill ensures your codebase remains robust, self-documenting, and easy to refactor during complex development tasks.
