Vercel's changelog announces that Cline is now available in the AI SDK harness layer.

By adding Cline as an adapter, developers can now use Cline within this harness, which likely simplifies the workflow for developing and validating agent behaviors. The announcement is brief, but it indicates a direct integration between Cline and the AI SDK's harness, expanding the tools available to developers who use Vercel's AI SDK. This update is part of Vercel's continuous improvements to its AI development ecosystem, and it provides a new option for developers who prefer Cline as their agent framework.
