How does the Result pattern improve code quality?

By treating errors as values rather than exceptions, it forces explicit error handling and prevents unhandled runtime crashes by making failure states visible to the compiler.

Why is Zod preferred in this skill?

Zod bridges the gap between compile-time types and runtime data, ensuring that external inputs match your expected TypeScript definitions exactly.

Can I use this for refactoring existing projects?

Yes, the skill provides specific patterns for eliminating 'any' types and migrating to strict type-safe configurations.

Does this skill support the latest TypeScript versions?

Yes, it specifically covers modern features from TypeScript 5.2 through 5.5+, including inferred predicates, 'satisfies', and resource management.

API 개발

Implements strict type safety and modern TypeScript patterns to ensure runtime reliability and eliminate type-related errors.

소개

This skill optimizes Claude's ability to write robust, enterprise-grade TypeScript by enforcing strict configurations, modern 5.5+ features, and runtime validation patterns. It helps developers eliminate the 'any' type, implement sophisticated domain modeling via branded types and discriminated unions, and handle errors predictably using the Result pattern. It is particularly useful when building complex systems where type-level documentation and runtime safety are paramount.
