# AI Kit API Reference

> Signatures and options for the main AI Kit classes.

This section documents the public classes and functions exported by `@ai_kit/core`. The next pages detail the constructors, options, and methods for `Agent`, `Workflow`, `WorkflowRun`, and `RuntimeStore`.

## Conventions

* Types come from the AI SDK whenever relevant (`LanguageModel`, `ToolSet`, …).
* Signatures are expressed in TypeScript; adapt them to your target language.
* Options marked as *optional* have defaults explained in the documentation.

See the dedicated pages:

* [`Agent`](/en/api-reference/agent)
* [`Workflow`](/en/api-reference/workflow)
* [`WorkflowRun`](/en/api-reference/workflow-run)
* [`RuntimeStore`](/en/api-reference/runtime-store)
