It refuses some special files, such as devices. Its refusal now says that the path names a device or process file that the tool does not read. Before, it said the device file would block or produce endless output.\n\n**Why**\n\nIf you see Claude unable to read one of these paths, the message is worded differently and now also names process files.\n\n- Area: Elsewhere\n- Tier: You'll notice\n- Useful: 1\/5\n- Signal: 1\/5\n- Scope: individual\n- Heads-up: no"}
