+# Draw.io Agent Frontend
+
+This directory contains the migrated Next.js draw.io intelligent drawing frontend for `ai-agent-scaffold-go`.
+
+## Backend API
+
+The frontend talks to the Go backend through:
+
+```text
+http://localhost:8091/api/v1
+```
+
+Override the API base URL with:
+
+```bash
+NEXT_PUBLIC_API_BASE_URL=http://localhost:8091/api/v1
+```
+
+Used endpoints:
+
+- `GET /query_ai_agent_config_list`
+- `POST /create_session`
+- `POST /chat`
+
+The Go chat endpoint returns:
+
+```json
+{
+  "code": "0000",
+  "info": "success",
+  "data": {
+    "content": "<agent output or draw.io xml>"
+  }
+}
+```
+
+The frontend treats `data.content` as draw.io XML when it looks like `mxfile` or `mxGraphModel`; otherwise it renders the content as a normal Agent message.
+
+## Development
+
+```bash
+npm install
+npm run dev
+```
+
+Open:
+
+```text
+http://localhost:3000
+```
+
+## Build

+```bash
+npm run build
+```
