What problem does it solve?

This Skill helps refactor code that uses optional fields or parallel booleans to represent state, making illegal states structurally impossible and improving code safety.

Core Features & Use Cases

  • State Modeling: Transforms ambiguous, optional-based state representations into strict, type-safe sum types (enums/discriminated unions).
  • Code Safety: Prevents invalid state combinations at compile time, reducing runtime errors and the need for manual validation.
  • Use Case: Refactor a UserStatus enum that currently uses optional fields like data? and error? into distinct variants like UserStatus.Loading, UserStatus.Success(Data), and UserStatus.Error(Error).

Quick Start

Refactor the provided TypeScript interface to use a discriminated union for its state.
