SDK Design

Design client libraries (SDKs) with excellent developer experience through intuitive APIs, robust error handling, automatic retries, and consistent patterns across programming languages.

When to Use This Skill

Core Architecture Patterns

Client → Resources → Methods

Organize SDK code hierarchically:
