Claude Code now knows a new one, `CLAUDE_CODE_DISABLE_RESPONSE_COMPARISON`. It is listed alongside variables such as `CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC`, `DISABLE_TELEMETRY` and `CLAUDE_CODE_DISABLE_WEB_FETCH`.\n\n**Why**\n\nA switch to turn off response comparison suggests Claude Code has a response comparison behaviour. If you turn off nonessential traffic or telemetry, check whether you also want to set this one.\n\n- Area: Settings\n- Names: `CLAUDE_CODE_DISABLE_RESPONSE_COMPARISON`\n- Tier: Use it now\n- Useful: 5\/5\n- Signal: 3\/5\n- Scope: both\n- Heads-up: no"}
