Data & privacy

• Web search sends queries to DuckDuckGo. Disable it in Agentic AI if you prefer no external queries.
• Memory is stored locally in agent_memory.json.

Troubleshooting

• Missing package or rename warning (duckduckgo_search → ddgs):

   pip install ddgs

• PyMuPDF issues on Windows: ensure you’re on a recent Python and run:

   pip install --upgrade pip
   pip install PyMuPDF
