"""
E2B Tools Example - Demonstrates how to use the E2B toolkit for sandboxed code execution.
This example shows how to:
1. Set up authentication with E2B API
2. Initialize the E2BTools with proper configuration
3. Create an agent that can run Python code in a secure sandbox
4. Use the sandbox for data analysis, visualization, and more
Prerequisites:
1. Create an account and get your API key from E2B:
- Visit https://e2b.dev/
- Sign up for an account
- Navigate to the Dashboard to get your API key
2. Install required packages:
uv pip install e2b_code_interpreter pandas matplotlib
3. Set environment variable:
export E2B_API_KEY=your_api_key
Features:
- Run Python code in a secure sandbox environment
- Upload and download files to/from the sandbox
- Create and download data visualizations
- Run servers within the sandbox with public URLs
- Manage sandbox lifecycle (timeout, shutdown)
- Access the internet from within the sandbox
Usage:
Run this script with the E2B_API_KEY environment variable set to interact
with the E2B sandbox through natural language commands.

"5. List files in the sandbox (list_files)",
"6. Read and write file content (read_file_content, write_file_content)",

"Guidelines:",
"- ALWAYS share the complete code with the user, properly formatted in code blocks",
"- Verify code functionality by executing it in the sandbox before sharing",
"- Iterate and debug code as needed to ensure it works correctly",
"- Use pandas, matplotlib, and other Python libraries for data analysis when appropriate",
"- Create proper visualizations when requested and add them as image artifacts to show inline",
"- Handle file uploads and downloads properly",
"- Explain your approach and the code's functionality in detail",
"- Format responses with both code and explanations for maximum clarity",
