# Quickstart: Plugin Architecture & Svelte Web UI

## Prerequisites
- Python 3.9+
- Node.js 18+
- npm or pnpm

## Setup

1. **Install Backend Dependencies**:
   ```bash
   cd backend
   python -m venv venv
   source venv/bin/activate  # or venv\Scripts\activate on Windows
   pip install -r requirements.txt
   ```

2. **Install Frontend Dependencies**:
   ```bash
   cd frontend
   npm install
   ```

## Running the Application

1. **Start Backend Server**:
   ```bash
   # From backend/ directory
   uvicorn src.app:app --reload --port 8000
   ```

2. **Start Frontend Dev Server**:
   ```bash
   # From frontend/ directory
   npm run dev
   ```

3. **Access the UI**:
   Open `http://localhost:5173` in your browser.

## Adding a Plugin

1. Create a new Python file in `backend/src/plugins/` (e.g., `my_plugin.py`).
2. Define your plugin class inheriting from `PluginBase`.
3. Implement `execute` and `get_schema` methods.
4. Restart the backend (or rely on auto-reload).
5. Your plugin should appear in the Web UI.
