A Claude Code environment variable, read out of the shipped bundle.
It has been in the build since v2.1.181, including the newest one read.
Set to 0 to make a non-interactive session report an idle status to its host at every turn end, even while background work is still running. By default, the session keeps reporting a running status past turn end while background work such as a background agent or a workflow run is still live. This keeps a host that watches the status, such as a remote session list, from announcing that Claude is waiting for your input mid-work. Background shell commands, such as a dev server, don't hold the running status. The running-status default and the 0 opt-out require Claude Code v2.1.269 or later; on earlier versions, set 1 to hold the running status
Set an environment variable to dump running tasks and teammate state whenever a session is judged idle.

The earliest release whose published evidence quoted CLAUDE_CODE_BG_TASKS_REPORT_RUNNING was v2.1.239, 21 Aug 2026. That is the oldest release this project wrote about it, so it is a floor on the name's age and not the release that introduced it. It is not a presence reading: which builds carried the name is the table below.

One row per release since the first build this name was read out of. Absent means the build was read and the name was not in it, never mined means no bundle for that release was ever archived, and a declared type or a default is only ever what that release's own bundle stated.

Read out of the published npm bundle release by release, and out of Anthropic's own documentation as this site captured it. Nothing on this page is a description anybody here wrote about what the environment variable does. All environment variables.
