 const tuiUsageText = `gitcrawl tui opens the local terminal cluster browser.
 
 Usage:
-  gitcrawl tui [owner/repo] [--limit N] [--min-size N] [--sort recent|size] [--hide-closed]
+  gitcrawl tui [owner/repo] [--limit N] [--min-size N] [--sort recent|oldest|size] [--hide-closed]
 
 If owner/repo is omitted, gitcrawl uses the most recently updated repository in the local database.
 The TUI starts with ghcrawl-style cluster display defaults: --min-size 5, --sort size, and closed historical clusters visible. Pass --min-size 1 for singleton clusters or --hide-closed to focus open-only.
