Implements high-quality TypeScript patterns to reduce cognitive load and improve code maintainability.
The Clean TypeScript skill guides Claude to treat TypeScript as a tool for correctness and clarity rather than empty ceremony. It enforces modern best practices such as favoring type aliases over interfaces, replacing enums with union types, and eliminating unsafe 'any' assertions. By focusing on explicit return types, predictable function signatures, and robust error handling through result objects, this skill ensures that generated code is robust, readable, and easy to maintain over the long term.
