@harness-kernel/provider-ai-sdk

@harness-kernel/provider-ai-sdk provides AiSdkModelProvider and createAiSdkModelProvider. It lets a runtime host bridge a Vercel AI SDK LanguageModel into the HarnessModelProvider contract.

import { createAiSdkModelProvider } from "@harness-kernel/provider-ai-sdk";

const provider = createAiSdkModelProvider({
  namespace: "custom",
  label: "Custom AI SDK Provider",
  resolveModel(model, input) {
    return resolveLanguageModel(model, input);
  },
});

The provider handles model messages, AI SDK tool wiring, streaming text deltas, context refresh between tool steps, and MessageDeltaEvent emission.

Use this package when your host already uses the AI SDK and wants to keep model provider ownership explicit.
