What
CLAUDE_CODE_TUI_TRIAL=fullscreen starts a session in the fullscreen renderer without saving the choice; it is read once at startup and then removed from the environment. The prompt offering fullscreen can be forced with CLAUDE_CODE_FORCE_FULLSCREEN_UPSELL, and is suppressed once you have a tui setting, under tmux control mode, on Windows SSH, and after it has been shown 3 times.
Details
- A trial session reports its renderer reason as
upsell_trial_onrather thansettings_on, which is how the rest of the code knows the choice is not yet persisted. - The showing count is tracked as
fullscreenUpsellSeenCountagainst a limit of 3. - The advertisement text is unchanged, but the check that decides whether to show it now also consults the crash auto-disable state.
Usage
