Claude Code used to always try to save incoming attachments to disk. In a session that writes no files to the machine's disk, it now refuses them with the reason: \"this session is diskless and writes no files to this machine's disk\".\n\n**Why**\n\nWhen an attachment does not arrive in such a session, you get a clear reason instead of an unexplained failure.\n\n- Area: Sessions\n- Tier: You'll notice\n- Useful: 2\/5\n- Signal: 3\/5\n- Scope: individual\n- Heads-up: no"}
