Cursor does RAG based on the active state of the editor (focused window, cursor location, recently touched files, etc). This works really well for copilot style small modifications, but it's unhelpful for larger changes, and can actually cause some context rot.

Claude only loads specific files (e.g. CLAUDE.md) and any files those reference with @syntax on load. Everything else is discovered using grep/find mostly.
