Harness.WinUI 1.0.10

Read-only mode. A lock button in the toolbar. While it's on, the agent can read and search, but anything that changes files or runs commands is refused, whatever you had allowed before (this includes tools an MCP App calls). The agent is told when you switch it. It isn't remembered across launches, so the app never starts locked.

Allow for this chat. The approval card has a new option: the same action runs without asking until you start a new chat or open another one. It isn't saved; "Always allow" still is.

Retry. When a reply fails or you stop it, a Retry button under it sends the same message again, with the agent back where it was before that message.

Shortcuts. Ctrl+N starts a new chat and Ctrl+H opens the history.

About. More menu → About Harness.WinUI shows the version, that the app is open source (MIT), and links to the source code, where to report an issue, the privacy policy and the third-party notices.

唯讀模式。 工具列新增鎖頭按鈕。開啟後，agent 只能讀取與搜尋，任何會修改檔案或執行指令的動作都會被拒絕，即使你之前設過允許也一樣（MCP App 發起的工具呼叫也包含在內）。切換時 agent 會被告知。唯讀模式不會被記住，所以 app 不會在啟動時就處於鎖定狀態。

本次對話都允許。 核准卡片多了一個選項：同一個動作在你開新對話或切換到別的對話之前，不會再詢問。這個選擇不會被儲存，「永遠允許」則照舊會。

重試。 回覆失敗或被你停止後，下方會出現「重試」按鈕，用同一句話再送一次，並讓 agent 回到那則訊息之前的狀態。

快速鍵。 Ctrl+N 開新對話，Ctrl+H 開對話紀錄。
