typescript-advanced-types

Quick Review

Exceptional skill documentation for TypeScript advanced types. The description clearly articulates when to use this skill (complex type logic, type-safe applications, reusable utilities). The content is comprehensive with extensive examples covering generics, conditional types, mapped types, template literals, utility types, and 6 sophisticated real-world patterns (type-safe event emitter, API client, builder pattern, deep readonly/partial, form validation, discriminated unions). Structure is logical with clear sections, though could benefit from splitting very large sections into separate files. The skill is highly novel—implementing these advanced type patterns from scratch would require extensive token usage and deep TypeScript expertise. Minor improvements could include more explicit CLI invocation examples and modularizing the longest sections, but overall this is production-ready documentation that significantly reduces complexity for agents working with advanced TypeScript types.
