Today we are adding Cline, which runs through the same `HarnessAgent`\n\ninterface as other supported harness.\n\n`@ai-sdk/harness-cline`\n\nis the official harness adapter for Cline, implemented in collaboration with the Cline team.\n\nCline runs fully in the host process and uses the sandbox as a remote filesystem and shell, so only its tools operate in the sandbox. No bridge process is installed inside the sandbox, similar to the existing Pi harness.\n\nRead the [Cline harness documentation](https://ai-sdk.dev/providers/ai-sdk-harnesses/cline) to get started.\n\nThe full supported list of harnesses is now: Claude Code, Cline, Codex, Deep Agents, Grok Build, OpenCode, and Pi, with more coming soon.", "url": "https://wpnews.pro/news/cline-is-now-available-in-the-ai-sdk-harness-layer", "canonical_source": "https://vercel.com/changelog/cline-harness-adapter", "published_at": "2026-08-18 00:00:00+00:00", "updated_at": "2026-08-18 18:42:05.061328+00:00", "lang": "en", "topics": ["ai-tools", "developer-tools", "ai-agents"], "entities": ["Vercel", "AI SDK", "Cline", "@ai-sdk/harness-cline", "Claude Code", "Codex", "Deep Agents", "Grok Build"], "alternates": {"html": "https://wpnews.pro/news/cline-is-now-available-in-the-ai-sdk-harness-layer", "markdown": "https://wpnews.pro/news/cline-is-now-available-in-the-ai-sdk-harness-layer.md", "text": "https://wpnews.pro/news/cline-is-now-available-in-the-ai-sdk-harness-layer.txt", "jsonld": "https://wpnews.pro/news/cline-is-now-available-in-the-ai-sdk-harness-layer.jsonld"}}
