CLAUDE_CODE_DISABLE_REFUSAL_FALLBACK

Updated October 23, 2026 by Alex Sorokoletov

CLAUDE_CODE_DISABLE_REFUSAL_FALLBACK is a Claude Code environment variable. Removed in v2.1.310, so current releases ignore it. It is listed in the official reference.

How to set it

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

export CLAUDE_CODE_DISABLE_REFUSAL_FALLBACK=<value>
claude

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

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