+# Runnable Recipe Examples
+
+This folder contains standalone, executable Python examples for each cookbook recipe. Each file can be run directly as a Python script.
+
+## Prerequisites
+
+- Python 3.8 or later
+- Install dependencies (this installs the local SDK in editable mode):
+
+```bash
+pip install -r requirements.txt
+```
+
+## Running Examples
+
+Each `.py` file is a complete, runnable program with executable permissions:
+
+```bash
+python <filename>.py
+# or on Unix-like systems:
+./<filename>.py
+```
+
+### Available Recipes
+
+| Recipe               | Command                          | Description                                |
+| -------------------- | -------------------------------- | ------------------------------------------ |
+| Error Handling       | `python error_handling.py`       | Demonstrates error handling patterns       |
+| Multiple Sessions    | `python multiple_sessions.py`    | Manages multiple independent conversations |
+| Managing Local Files | `python managing_local_files.py` | Organizes files using AI grouping          |
+| PR Visualization     | `python pr_visualization.py`     | Generates PR age charts                    |
+| Persisting Sessions  | `python persisting_sessions.py`  | Save and resume sessions across restarts   |
+
+### Examples with Arguments
+
+**PR Visualization with specific repo:**
+
+```bash
+python pr_visualization.py --repo github/copilot-sdk
+```
+
+**Managing Local Files (edit the file to change target folder):**
+
+```bash
+# Edit the target_folder variable in managing_local_files.py first
+python managing_local_files.py
+```
+
+## Local SDK Development
+
+The `requirements.txt` installs the local Copilot SDK using `-e ../..` (editable install). This means:
+
+- Changes to the SDK source are immediately available
+- No need to publish or install from PyPI
+- Perfect for testing and development
+
+If you modify the SDK source, Python will automatically use the updated code (no rebuild needed).
+
+## Python Best Practices
+
+These examples follow Python conventions:
+
+- PEP 8 naming (snake_case for functions and variables)
+- Shebang line for direct execution
+- Proper exception handling
+- Type hints where appropriate
+- Standard library usage
+
+## Virtual Environment (Recommended)
+
+For isolated development:
+
+```bash
+# Create virtual environment
+python -m venv venv
+
+# Activate it
+# Windows:
+venv\Scripts\activate
+# Unix/macOS:
+source venv/bin/activate
+
+# Install dependencies
+pip install -r requirements.txt
+```
