User: "Check if Django 4.2 is compatible with Python 3.9"
AI Assistant: I'll check Django 4.2's compatibility with Python 3.9 for you.
[Uses get_package_info and check_package_python_compatibility tools]
User: "What are the main dependencies of FastAPI?"
AI Assistant: Let me get the dependency information for FastAPI.
[Uses get_package_dependencies tool]
User: "Show me the download statistics for the requests package and tell me which is more popular: requests or urllib3?"
AI Assistant: I'll get the download statistics for both packages and compare their popularity.
[Uses get_download_statistics tool for both packages]
