+端级工作台（workbench shell）：`AgentHubWorkbench` 主壳、GlobalRail/会话侧栏/
+右侧 Inspector、UnifiedComposer、WorkbenchRoutes 页面路由、agents/contacts/
+docs/projects/tasks/settings 页面、mainchain 状态条、terminal host、floating
+组件与 team subagent stream 等。
+
+由 `app/shared/src/workbench/` 独立而来（#1759）：`shared` 是跨端原语层，
+workbench 是端级巨石，两者拆包后依赖方向固定为 **workbench → shared 单向**。
+
+## 边界
+
+- 依赖方向：`workbench` 可以 import `shared`（深导入走 `@shared/*` 别名，
+  与 web/desktop 约定一致）；**shared 永远不得 import workbench**
+  （`scripts/verify/verify-frontend-package-boundary.py` + eslint
+  `no-restricted-imports` 双重机器门禁）。
+- 消费者：web / desktop 从 `@agenthub/workbench`（及显式子路径
+  `./hubDataMapping`、`./pages`、`./designIcons`、`./desktopChromeEvents`、
+  `./WorkbenchRoutes`）导入。
+- mobile-rn 不依赖本包（Hub-only，boundary verifier 禁止 workbench 导入）。
+
+## 常用命令
+
+```bash
+pnpm --filter @agenthub/workbench test          # vitest 全量
+pnpm --filter @agenthub/workbench test:coverage # 覆盖率（门禁同源阈值）
+pnpm --filter @agenthub/workbench typecheck     # tsc --noEmit
+```
+
+图标治理：workbench 内图标一律走 `designIcons.tsx` registry
+（`icon-governance.test.ts` 机器把关，禁止直连 lucide-react/@lobehub/icons
+或裸 `<svg>`）。
