380380* **Commands Claude runs**: a cloud environment doesn't set its own command timeout, so the Bash tool's defaults apply. Claude waits 2 minutes for a foreground command by default and can ask for up to 10 minutes.

382 When a command reaches its [timeout](/docs/en/tools-reference#timeout-and-output-limits), Claude Code [moves it to the background](/docs/en/tools-reference#background-commands) instead of stopping it, unless the command starts with `sleep`. A command moved this way can keep running for up to 30 more minutes before Claude Code stops it at its [background time limit](/docs/en/tools-reference#background-commands). Setting `BASH_DEFAULT_TIMEOUT_MS` above `1800000` milliseconds lengthens that limit as well as the foreground default.
382 When a command reaches its [timeout](/docs/en/tools-reference#timeout-and-output-limits), Claude Code [moves it to the background](/docs/en/tools-reference#foreground-commands-that-move-to-the-background) instead of stopping it, unless the command starts with `sleep`. A command moved this way can keep running for up to 30 more minutes before Claude Code stops it at its [background time limit](/docs/en/tools-reference#time-limit-for-background-commands). Setting `BASH_DEFAULT_TIMEOUT_MS` above `1800000` milliseconds lengthens that limit as well as the foreground default.
383383* **SessionStart hooks**: Claude Code cancels a `command` hook after 600 seconds unless you set [`timeout`](/docs/en/hooks#common-fields), in seconds, on the hook entry. Claude Code doesn't enforce the timeout on a hook you run with [`async: true`](/docs/en/hooks#run-hooks-in-the-background).
384384* **Setup script**: a script that takes longer than roughly five minutes isn't cached. [Script requirements](#script-requirements) covers how to stay under that.
385385* **Idle sessions**: after a few minutes without activity, a session's VM pauses with its files saved, and a paused VM can later be reclaimed. [Set environment variables](#set-environment-variables) describes what a session picks up in each case, and [Environment expired](/docs/en/claude-code-on-the-web#environment-expired) covers how to reopen a session whose VM was reclaimed.
