Harness Adapters | AI SDK 한국어

Harness adapters connect HarnessAgent to a specific agent runtime. They are the harness equivalent of AI SDK model providers: each adapter wraps one runtime and normalizes its sessions, stream events, tools, usage, lifecycle state, and configuration into the harness contract.
