+
+## Overview
+
+AI Agent 沉浸式 3D 命令中心——一个 VisionOS + WebXR 应用，为 AI Agent 编排提供空间化的监控、构建和协作环境。
+
+由 8 个 [[The-Agency]] 专业 Agent 并行协作规划（[[nexus-spatial-discovery]]），10 分钟 wall-clock time 产出完整产品规划。
+
+## Core Capabilities
+
+- **3D Node Graph Visualization**：将 Agent 工作流可视化为 3D 节点图，数据流朝向用户
+- **Real-time Spatial Monitoring**：实时监控面板以空间面板形式展示
+- **Drag-and-Drop 3D Workflow Building**：3D 空间内拖放构建工作流
+- **Shared Spatial Collaboration**：多人进入共享 3D 空间协作
+- **AI Support Agent in Workspace**：支持代理以内嵌节点形式存在于用户空间工作区
+
+## Pricing
+
+| Tier | Price | Target |
+|------|-------|--------|
+| Explorer | Free | 开发者、solo builders（3 agents，WebXR viewer）|
+| Pro | $99/user/month | 小团队（25 agents，协作）|
+| Team | $249/user/month | 中型 AI 团队（unlimited agents，分析）|
+| Enterprise | Custom ($2K-10K/mo) | 大型企业（SSO，RBAC，on-prem，SLA）|
+
+## Strategy
+
+- **Phase 1 (Months 1-6)**：2D web dashboard with Three.js 2.5D → 50 paying teams，$60K MRR
+- **Phase 2 (Months 6-12)**：WebXR spatial mode → 200 teams，$300K MRR
+- **Phase 3 (Months 12-18)**：Native VisionOS app（仅在 spatial 需求验证后）→ 500 teams，$1M+ MRR
+
+## Technical Architecture
+
+- Orchestration engine：Rust（亚毫秒调度，零 GC 停顿）
+- WebXR client：TypeScript + React Three Fiber
+- VisionOS client：Swift 6 + SwiftUI + RealityKit
+- Collaboration：Yjs (CRDT) + WebRTC
+- 8-service architecture：Auth / Workspace / Workflow / Orchestration / Collaboration / Streaming / Plugin / Billing
+
+## Key Insights from Discovery
+
+1. **2D-first, spatial-second**：所有 8 个 Agent 独立得出相同结论
+2. **Debugging is the killer use case**：空间叠加调试追踪是 3D 真正优于 2D 的场景
+3. **WebXR over VisionOS**：~100 万 Vision Pro 安装量无法支撑业务；Safari 2025 年末采纳 WebXR
+4. **"War room" collaboration**：多人共享 3D 空间进行事故响应是最强的空间价值主张
