After user lost 6 months of work to `rm -rf ~/.claude`, ALL 4 uninstall
scripts (claude, codex, gemini, qwen) now require explicit choice:
Modes:
1) safe (default) — remove binary + env + settings.json
KEEP projects, history, commands(skills),
plans, file-history, plugins
2) settings-only — clear settings.json only, keep binary + data
3) full — wipe everything (tar backup first, requires
typing 'WIPE' to confirm)
4) cancel — exit, do nothing
Default flow:
- Interactive prompt with PREVIEW of user data (size, project count,
command count, history line count) before any destructive op
- Cancel option always available
- Each file backed up to *.uninstall.bak.<TS> before removal
- /etc/environment + .bashrc + /etc/profile.d backed up before sed
Non-interactive (CI / scripts):
UCLAUDE_MODE=safe sudo bash uclaude_uninstall.sh
UCLAUDE_MODE=full sudo bash uclaude_uninstall.sh # creates tar backup
UCLAUDE_YES=1 # skip prompt, default to safe mode
NEVER again should an uninstaller silently destroy user data.
Per-tool env vars: UCLAUDE_MODE / UCODEX_MODE / UGEMINI_MODE / UQWEN_MODE.
