# AI SDK harness层支持原生订阅认证，切换编码代理无需改代码

Vercel 的 AI SDK harness 层现在支持通过harness自身的原生订阅进行认证（前提是底层harness支持）。该层用统一的 HarnessAgent 接口运行不同的编码代理，开发者切换代理时无需改动应用代码。这简化了多代理切换的认证流程，对需要在不同编码代理之间灵活切换的开发者来说，集成成本进一步降低。

## English Version

**AI SDK Harness Layer Adds Native Subscription Auth for Coding Agents**

Vercel's AI SDK harness layer now supports authenticating harnesses through their native subscriptions where the underlying harness allows it. The layer runs different coding agents through the same HarnessAgent interface, letting developers switch agents without changing application code. This simplifies authentication for multi-agent setups and lowers integration overhead for teams that need flexibility across coding agents.
