CLAUDE_CODE_SKIP_FAST_MODE_ORG_CHECK

Updated October 13, 2026 by Alex Sorokoletov

CLAUDE_CODE_SKIP_FAST_MODE_ORG_CHECK is a Claude Code environment variable: Disables the organization-level eligibility check for fast mode. Fast mode (toggled via /fast) normally verifies that the user's organization supports it. Removed in v2.1.293, 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_SKIP_FAST_MODE_ORG_CHECK=<value>
claude

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

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