Why does this skill discourage the use of the 'any' type?

Using 'any' bypasses the TypeScript compiler's safety checks. The skill promotes the use of 'unknown' combined with type predicates and guards to ensure your code is truly type-safe at runtime.

When should I use 'type' over 'interface' with this skill?

This skill defaults to 'type' for most definitions. You should only use 'interface' for declaration merging with third-party libraries or when defining a contract for a class.

How does Zod help with TypeScript types?

Zod allows you to create a single schema that validates data at runtime (like API responses) while automatically inferring the corresponding TypeScript types for your development environment.

Can this skill help validate external configuration files?

Yes, it provides patterns for using Zod to parse and validate environment variables, JSON configs, and form inputs to ensure they meet your application's requirements before execution.

Developer Tools

Enforces best-practice TypeScript type definitions and implements robust runtime data validation using Zod.

This skill provides a standardized framework for TypeScript development, focusing on type safety and architectural consistency. It guides developers on choosing between types and interfaces, mandates the use of unknown over any with proper type guards, and implements robust runtime validation for external data using Zod. By applying these patterns, the skill helps eliminate runtime errors, ensures data integrity from APIs and forms, and maintains a clean, scalable codebase through consistent type-level programming.

Key Features

01Elimination of unsafe 'any' types in favor of 'unknown' and type guards

02Implementation of string literal union types over TypeScript enums

03Integration of Zod for schema-based runtime validation of external data

04Standardized decision logic for type vs interface usage
