+\# Agent Collaboration Example
+
+
+
+This sample demonstrates how multiple AI agents can collaborate using
+
+Microsoft Semantic Kernel.
+
+
+
+\## Agents
+
+\- Planner: breaks a task into steps
+
+\- Executor: executes the plan and produces output
+
+
+
+\## How it Works
+
+1\. User provides a task
+
+2\. Planner agent creates a plan
+
+3\. Executor agent produces the final response
+
+
+
+\## Requirements
+
+\- Python 3.9+
+
+\- OpenAI API key set as an environment variable
+
+
+
+\## Run
+
+```bash
+
+python main.py
+
+
+
