Harness.WinUI 1.0.9

Copy buttons. Every finished code block has a copy button that copies just the code, and each reply has one in its footer that copies the reply's text. They appear when you point at them, and the layout of the conversation doesn't change.

Skills from the message box. Type / at the start of a message to list your skills, filtered as you type. Pick one with the arrow keys and Enter or Tab (or a click), then write your request: the agent is told to load and follow that skill. The conversation shows just what you typed.

History.

• A search box finds a conversation by its title or anything said in it.
• Each conversation has a "⋯" menu to rename it or export it as a Markdown file.

Observability.

• Statistics shows the prompt-cache hit rate, overall and per model. A provider that doesn't report cached tokens shows a dash instead of 0%.
• The labels now explain themselves: hover a card to see what it counts, and each table has a short note on its columns. The AI analysis also looks at the cache hit rate.

複製按鈕。 每個完成的程式碼區塊都有複製按鈕（只複製程式碼），每則回覆的頁尾也有一個（複製回覆的文字）。滑鼠移上去才會出現，不會改變對話的版面。

在訊息框用 / 選技能。 訊息一開頭輸入 / 會列出你的技能，並隨著輸入篩選。用方向鍵加 Enter 或 Tab（或直接點選）選好後再寫需求，agent 會被告知載入並照著這個技能做。對話裡只會顯示你打的字。

對話紀錄。

• 新增搜尋框，可以用標題或對話中說過的內容找對話。
• 每個對話旁有「⋯」選單，可以重新命名，或匯出成 Markdown 檔。

觀測。

• 統計頁新增提示快取命中率（整體與各模型）。供應商沒有回報快取 token 時會顯示「—」，不會誤顯示成 0%。
• 說明文字更清楚：滑鼠停在卡片上會說明它統計什麼，每張表格上方有各欄位的簡短說明。AI 分析也會看快取命中率。

下載後解壓縮，執行 Harness.WinUI.exe 即可。
