Does this stop you from using Cursor

No - Cursor works, but with this issue

Hey @Samuel_Talenti
Almost all of that is User/globalStorage/state.vscdb - your local chat/agent history, which currently grows with no age limit. Nothing’s broken, and it’s an issue we’re tracking. To reclaim space safely:

  1. Fully quit Cursor and check ~/Library/Application Support/Cursor/User/globalStorage/ - a large state.vscdb.backup there is safe to delete (leave state.vscdb itself alone).
  2. Reopen Cursor and run Developer: GC Agent KV Blobs (Cmd+Shift+P) to compact the DB without deleting any chats.
  3. Still large? Run Developer: Delete Old Chats…, pick an age cutoff, then it compacts - back up state.vscdb first if you want to keep older history.

Heads up: compaction temporarily needs free space roughly equal to the DB size, and may not reclaim everything in one pass. If it barely shrinks, reply with the before/after sizes and I’ll walk you through a full reset.
