Small differences between almost-identical types can balloon maintenance and duplicate logic. This Skill promotes unifying such types to simplify modeling and reduce boilerplate.
Refactor two near-identical types into a single unified type with clear variant indicators where differences matter.

Unify similar TypeScript interfaces by refactoring them into a single interface containing common fields and explicit variant indicators for differences, which eliminates duplicate type definitions and reduces maintenance overhead.
Repeated narrowing logic often occurs when union types are mostly identical but modeled separately. Unifying these types into a single coherent model with clear variant fields reduces parallel type hierarchies and eliminates redundant narrowing.
Reduce type duplication by consolidating near-identical data models into a single unified type with clearly defined variant indicators, which keeps APIs coherent while preserving explicit semantic differences.
Refactor TypeScript types by merging shared properties into a base structure and applying variant indicators for divergent fields. This preserves domain logic semantics while actively reducing boilerplate and parallel hierarchies.
You should not unify similar types when structural or semantic differences between the types are fundamental. In these cases, carefully justified separation is required instead of forcing a single unified interface.
