A lot has happened since the alpha, and Alem, Jack, and Tom have put an incredible amount of work into getting here.

That one more thing is an agent harness.
Build an agent that keeps its session between requests, takes new instructions while it works, and runs in your terminal, web app, or editor.
The harness APIs are experimental, and we'd love for you to try them.

@tan_stack モデルだけでなくUIフレームワークやインフラまで選べるのは、既存のアプリに合わせて段階的に組み込みやすそうですね。実装時はストリーミングやツール呼び出しの境界が揃っていると、モデルを替える時も助かります。

@tan_stack in 1.0, does the agent harness log tool steps apart from the chat ui, or do you ship that as one package?
