On Linux, Claude Code checks that the system has what the sandbox needs and lists warnings for anything missing. Before, that list came from a check for seccomp (a Linux feature that limits what a program may do) and a permission check. It now runs one extra check and adds its message to the warnings.\n\n**Why**\n\nYou may see a sandbox warning on Linux that you did not see before.\n\n- Area: Sandbox\n- Tier: You'll notice\n- Useful: 1\/5\n- Signal: 1\/5\n- Scope: individual\n- Heads-up: no"}
