 - **Smart framework detection** : automatically identifies Node.js, Next.js, Python, Django, FastAPI, Rust, Go, Ruby and applies the right exclusion rules for each
 - **Respects your `.gitignore`** : patterns from your existing gitignore are honoured automatically
+- **Git-aware packaging** : package only modified, staged, unstaged, and untracked files with `--git-changes` — perfect for AI review sessions, incremental debugging, and PR workflows
 - **Warns before it's a problem** : flags large files (≥ 1 MB) and binary files that AI tools can't read, before you waste an upload
 - **Handles the messy stuff** : dangling symlinks, unreadable files, and files outside the project tree are all caught and reported, never silently dropped
 - **Full CLI control** : `--include`, `--exclude`, `--dry-run`, `--verbose`, `--output`, all composable
