+# Agent.md
+
+## 1. Deployment Configuration
+
+### Target Space
+- **Profile:** `AUXteam`  
+- **Space:** `Maxun`  
+- **Full Identifier:** `AUXteam/Maxun`  
+- **Frontend Port:** `7860` (mandatory for all Hugging Face Spaces)
+
+### Deployment Method
+- **Docker SDK** — for all other applications (recommended default for flexibility)
+
+### HF Token
+- The environment variable **`HF_TOKEN` will always be provided at execution time**.
+- Never hardcode the token. Always read it from the environment.
+- All monitoring and log‑streaming commands rely on `HF_TOKEN`.
+
+### Required Files
+- `Dockerfile`
+- `README.md` with Hugging Face YAML frontmatter:
+  ```yaml
+  ---
+  title: Maxun
+  sdk: docker
+  app_port: 7860
+  ---
+  ```
+- `.hfignore` to exclude unnecessary files
+- This `Agent.md` file (must be committed before deployment)
+
+---
+
+## 2. API Exposure and Documentation
+
+### Mandatory Endpoints
+Every deployment **must** expose:
+
+- **`/health`**  
+  - Returns HTTP 200 when the app is ready.  
+  - Required for Hugging Face to transition the Space from *starting* → *running*.
+
+- **`/api-docs`**  
+  - Documents **all** available API endpoints.  
+  - Must be reachable at:  
+    `https://AUXteam-Maxun.hf.space/api-docs`
+
+### Functional Endpoints
+- **Method:** GET
+- **Path:** `/api/runs/{run_id}/vision`
+- **Purpose:** Get VNC connection details for a run
+- **Request Example:** `GET /api/runs/1/vision`
+- **Response Example:** 
+  ```json
+  {
+    "status": true,
+    "vnc_url": "http://localhost:6080/vnc.html?autoconnect=true&resize=scale",
+    "has_vnc": true
+  }
+  ```
+
+---
+
+## 3. Deployment Workflow
+
+### Standard Deployment Command
+After any code change, run:
+
+```bash
+hf upload AUXteam/Maxun --repo-type=space
+```
+
+This command must be executed **after updating and committing Agent.md**.
+
+### Deployment Steps
+1. Ensure all code changes are committed.  
+2. Ensure `Agent.md` is updated and committed.  
+3. Run the upload command.  
+4. Wait for the Space to build.  
+5. Monitor logs (see next section).  
+6. When the Space is running, execute all test cases.
+
+### Continuous Deployment Rule
+After **every** relevant edit (logic, dependencies, API changes):
+
+- Update `Agent.md`
+- Redeploy using the upload command
+- Re-run all test cases
+- Confirm `/health` and `/api-docs` are functional
+
+This applies even for long-running projects.
+
+---
+
+## 4. Monitoring and Logs
+
+### Build Logs (SSE)
+```bash
+curl -N \
+  -H "Authorization: Bearer $HF_TOKEN" \
+  "https://huggingface.co/api/spaces/AUXteam/Maxun/logs/build"
+```
+
+### Run Logs (SSE)
+```bash
+curl -N \
+  -H "Authorization: Bearer $HF_TOKEN" \
+  "https://huggingface.co/api/spaces/AUXteam/Maxun/logs/run"
+```
+
+### Notes
+- If the Space stays in *starting* for too long, `/health` is usually failing.  
+- If the Space times out after ~30 minutes, check logs immediately.  
+- Fix issues, commit changes, redeploy.
+
+---
+
+## 5. Test Run Cases (Mandatory After Every Deployment)
+
+These tests ensure the agentic system can verify the deployment automatically.
+
+### 1. Health Check
+```
+GET https://AUXteam-Maxun.hf.space/health
+Expected: HTTP 200, body: {"status": "ok"} or similar
+```
+
+### 2. API Docs Check
+```
+GET https://AUXteam-Maxun.hf.space/api-docs
+Expected: HTTP 200, valid documentation UI or JSON spec
+```
+
+### 3. Functional Endpoint Tests
+- Example request:
+```
+GET https://AUXteam-Maxun.hf.space/api/runs/1/vision
+```
+- Expected response structure:
+```json
+{
+  "status": true,
+  "vnc_url": "...",
+  "has_vnc": true
+}
+```
+- Validation criteria: HTTP 200, JSON response with keys `status`, `vnc_url`, `has_vnc`.
+
+### 4. End-to-End Behaviour
+- Confirm the UI loads (if applicable)
+- Confirm API endpoints respond within reasonable time
+- Confirm no errors appear in run logs
+
+---
+
+## 6. Maintenance Rules
+
+- `Agent.md` must always reflect the **current** deployment configuration, API surface, and test cases.
+- Any change to:
+  - API routes  
+  - Dockerfile  
+  - Dependencies  
+  - App logic  
+  - Deployment method  
+  requires updating this file.
+- This file must be committed **before** every deployment.
+- This file is the operational contract for autonomous agents interacting with the project.

+     - Test: Add a unit test in `tests/` checking if the endpoint returns valid connection info.
+   - Task 2 (Backend WS): Broadcast screenshots.
+     - Update WebSocketManager in `src/magentic_ui/backend/web/managers/websocket.py` to relay `screenshot` type messages from agents like `FaraWebSurfer`.
+     - Test: Unit test the WebSocketManager to ensure `screenshot` messages are broadcasted properly.
+   - Task 3 (Frontend): Implement Tabs in Chat UI.
+     - Update `frontend/src/components/views/chat/chat.tsx` to wrap the chat interface in an Ant Design `<Tabs>` component (Chat vs Vision).
+     - Test: Write a Playwright test ensuring the Tabs render and clicking 'Vision' switches the view.
+   - Task 4 (Frontend): Implement Vision Component.

+
+3. **Functionality Expectations**
+   - User perspective: User clicks 'Vision' tab and sees exactly what the agent sees (browser viewport, desktop) via VNC or updating screenshots. Switching tabs doesn't interrupt the run. The app is accessible on Hugging Face Spaces.
+   - Technical perspective: Agents emit visual state. Backend routes it to the frontend via WS or provides a VNC endpoint. Frontend maintains connection regardless of active tab. Docker container serves the app on port 7860.
+   - Constraints: VNC requires Docker configuration exposing the noVNC port. Fallback to screenshots if VNC is unavailable. HF Space deployment constraints apply.
+
+4. **API Endpoints to be Exposed**
+   - `GET /health` (Required by HF)
+   - `GET /api-docs` (Required by HF)
+   - `GET /api/runs/{run_id}/vision`
+     - Request: None
+     - Response: `{ "status": true, "vnc_url": "ws://localhost:5900", "has_vnc": true }`
+     - Auth: Inherits existing run access auth.
+   - WebSocket `/api/ws/runs/{run_id}` (Existing, modified)
+     - New message type from server: `{ "type": "screenshot", "data": "base64_encoded_image_string" }`
