A command can run in the background with the `run_in_background` option, which lets Claude carry on while it runs.\n\nIn this version, Claude's instructions for the Bash tool no longer explain how `timeout` applies to background commands. The removed text said `timeout` sets how long such a command may run (default 1800000, maximum 7200000), and that at the limit the command is stopped and Claude is called back.\n\n**Why**\n\nClaude now gets less guidance about how long background commands may run. That may mean the timeout itself behaves differently, so watch long background commands.\n\n- Area: Bash Tool\n- Names: `run_in_background`\n- Tier: Under the hood\n- Useful: 1\/5\n- Signal: 1\/5\n- Scope: individual\n- Heads-up: no"}
