AI SDK harness layer now supports native subscription authentication
UpdateVerifiedAdded Sep 22, 2026
The AI SDK harness layer now supports authenticating harnesses through their native subscriptions, where the underlying harness supports them. The harness layer runs different coding agents through the same HarnessAgent interface, so you can switch agents without changing your application code. No code changes or new settings are required.
