AUP

WordPress and Astro both ask a site to declare its content model. That is not a flaw; it is a different trade-off. ARC's Web Device tries to make common web work a runtime, while leaving the meanings of products, terms, and events to object data and application components. This is about where that boundary belongs, and what still has to be supplied to make it hold.

Web Device is one of ARC's core capabilities: declare a .web/ folder anywhere in AFS, and the data and AUP under it get rendered server-side into a website, SEO checks, broken-link detection, and visitor analytics included for free. This piece covers how it differs from UI Device (/dev/ui/web), how to use it, and which situations call for which.

ArcBlock founder and CEO Robert Mao will give a keynote at the 1st Harness4GenUI workshop, held during ASE 2026 in Munich, Germany.

Blocklet 的執行時。它給開發者一個地方來執行以 Blocklet 描述的應用，連同那個 Blocklet 宣告自己需要的資源。

AFS（Agentic File System）把與任務有關的檔案、服務和正在進行的工作組織成可檢視的資源檢視。它不是把一整台機器或一堆 API 交給 agent，而是給任務一塊有名字、有邊界的工作範圍。

ARC 是 Blocklet 的 runtime。它讓開發者把應用、執行位置和所需資源分別說清楚：Blocklet 描述應用，ARC 執行它，AFS 表達它要接觸的資源。

把瀏覽器當作一個可以即時操作的 device，AUP 直接在瀏覽器裡算繪。

在 AFS 目錄下宣告一個 .web/，這個目錄裡的資料和 AUP 就會在伺服器端被算繪成一個網站。

一項任務的 context 包括相關資料、可用工具和允許的操作。它們被放進清楚的範圍裡，agent 才知道該從哪裡找資訊、能用什麼完成工作。
