## What it is
A macOS shell-based CLI tool that automatically excludes development dependency directories (like node_modules, .venv, target) from Apple Time Machine backups. It scans the home directory for dependency folders paired with sentinel config files and registers them with Time Machine, running daily via a service.

## Use cases
- stop time machine backing up node_modules
- exclude .venv and target folders from mac backups
- reduce time machine backup size for developer projects
- automatically skip dependency directories in backups
- free up time machine disk space on macos
- exclude build artifacts from backups

## When to choose
- you develop on macOS and use Time Machine
- your backups are bloated with node_modules, .venv, or build directories
- you want a set-and-forget daily exclusion tool installed via Homebrew

## When to avoid
- you don't use macOS or Time Machine
- you want to back up dependency folders for full restore without reinstalling
- you need a cross-platform backup solution
