Its description is the text that tells Claude how to use it. That description now says a background command, one that keeps running while Claude carries on, has a default time limit of 600000 milliseconds, which is 10 minutes. Before, it said 1800000 milliseconds, which is 30 minutes. The maximum is still 7200000 milliseconds, which is 2 hours. The description also tells Claude that a command which reaches its limit is stopped and Claude is called again.\n\n**Why**\n\nIf you rely on long background jobs such as builds or test runs, Claude is now told to expect them to stop after 10 minutes unless a longer limit is set.\n\n- Area: Bash Tool\n- Tier: You'll notice\n- Useful: 3\/5\n- Signal: 2\/5\n- Scope: individual\n- Heads-up: yes"}
