+## 🖥️ Local Web GUI
+
+If the terminal isn't your thing, launch the bundled browser GUI:
+
+```bash
+python3 -m src.gui --cwd . --allow-write --allow-shell
+```
+
+Your default browser opens to `http://127.0.0.1:8765` with a modern dark-themed chat UI.
+
+| Flag | Description |
+|------|-------------|
+| `--host <addr>` | Bind address (default `127.0.0.1`) |
+| `--port <n>` | Port to listen on (default `8765`) |
+| `--cwd <path>` | Workspace directory the agent operates in |
+| `--model <name>` | Override the model name |
+| `--base-url <url>` | Override the OpenAI-compatible API base URL |
+| `--api-key <key>` | API key for the model server |
+| `--session-dir <path>` | Where saved sessions live |
+| `--allow-write` | Allow file write/edit tools |
+| `--allow-shell` | Allow shell execution |
+| `--no-browser` | Don't auto-open a browser tab |
+
+The GUI surfaces:
+
+- multi-turn chat with tool-call cards (collapsible JSON args + results)
+- saved sessions sidebar with one-click resume
+- slash command and skill pickers (`/` and `★` buttons, or `Cmd/Ctrl+K`)
+- live settings panel (model, base URL, working dir, permissions)
+- usage / cost meta in the composer footer
+
+> **Note:** The GUI uses [FastAPI](https://fastapi.tiangolo.com/) and [Uvicorn](https://www.uvicorn.org/) under the hood. These get installed automatically if you install the package via `pip install -e .`. The core Python agent runtime itself remains dependency-free.

 ## 🔄 Session Persistence
 
 Each `agent` run automatically saves a resumable session:
