CLAUDE_CODE_FORCE_FULLSCREEN_UPSELL

Updated October 13, 2026 by Alex Sorokoletov

CLAUDE_CODE_FORCE_FULLSCREEN_UPSELL is a Claude Code environment variable: Forces the fullscreen TUI upsell prompt past the normal fullscreenUpsellSeenCount cap and the tengu_ochre_hollow gate. Internal test/demo affordance. Added between v2.1.108 and v2.1.114 and still present in v2.1.294. 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_CODE_FORCE_FULLSCREEN_UPSELL=<value>
claude

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

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