The harness layer lets your application run different coding agents through the same `HarnessAgent`\n\ninterface, so you can switch agents without changing your application code.\n\nPass `cursor`\n\nto `HarnessAgent`\n\n:\n\nUnder the hood, the adapter uses [ @ai-sdk/harness-acp](https://vercel.com/changelog/use-acp-compatible-harnesses-with-the-ai-sdk-harness-layer) to connect Cursor to\n\n`HarnessAgent`\n\nthrough the Agent Client Protocol (ACP).
