What problem does it solve?
TypeScript projects often have fragile or inconsistent type definitions, duplicated runtime values, inline nested types, and unsafe uses of any; this Skill provides concise patterns and best practices to make types reliable, refactorable, and aligned with runtime values for safer and more maintainable code.
Core Features & Use Cases
- Single-source-of-truth runtime enums: prefer creating const objects and deriving union types to enable autocomplete, runtime validation, and easier refactors.
- Flat interface design: extract nested inline object types into dedicated interfaces to improve clarity, reuse, and extendability across domains and APIs.
- Strict typing guidance: avoid any, prefer unknown with type guards, use utility types, and import type annotations to keep public APIs explicit.
Use cases include migrating legacy TypeScript code, enforcing repository-wide style during code review, and scaffolding new modules with robust type-safe patterns.
Quick Start
Refactor my TypeScript file to replace inline union strings with a const object extraction pattern, extract nested inline object types into named interfaces, and remove uses of any by introducing appropriate type guards and utility-type transformations.
