Contract Diff

Set up a new bot for me I can hand two PDFs. Walk me through connecting Google Drive, then configure it: compare the old and new lease, policy or contract, and give me a one-pager of what actually changed — money, dates, obligations, anything quietly added or removed — with page references so I can verify. Ask me nothing it can read for itself. Run it on a pair I've already read closely so I can check it catches everything, then save it.
