CLAUDE_BG_POST_CLEAR_RESPAWN

Updated October 14, 2026 by Alex Sorokoletov

CLAUDE_BG_POST_CLEAR_RESPAWN is a Claude Code environment variable. Removed in v2.1.295, so current releases ignore it. It is not in the official reference.

How to set it

For one session, export it in the shell that starts Claude Code:

export CLAUDE_BG_POST_CLEAR_RESPAWN=<value>
claude

To apply it to every session, add it to the env object of a settings file:

// ~/.claude/settings.json
{
  "env": {
    "CLAUDE_BG_POST_CLEAR_RESPAWN": "<value>"
  }
}
