What problem does it solve?

Duplicated type definitions lead to inconsistencies, maintenance burden, and bugs. This skill shows how to derive types from a single source of truth using TypeScript's type operations and generics, so types stay in sync automatically.

Core Features & Use Cases

• Derive types from base definitions using extends, Pick, Partial, and keyof to create related variants (e.g., optional versions, subsets, or derived types).
• Promote base + extensions, input/output types, and mapped/utility types to reduce drift across interfaces and data structures.
• Real-world scenarios include keeping User, Form, and API response types aligned without duplicating fields.

Quick Start

Create or identify a base interface and derive a new type with Partial and Pick to produce an update model.
