SDK
A software development kit that packages an API into libraries, types, and helpers for a programming language.
Definition
SDKs handle authentication, retries, streaming, and typed responses so developers can integrate AI capabilities quickly. Official SDKs track API changes and document supported features; community SDKs cover additional languages. Choosing tools with mature SDKs in your stack reduces integration effort.
Why it matters when choosing a tool
A good SDK shortens time to integration and reduces subtle bugs around streaming, tool calls, and error handling.
