You’ve written Bash scripts before. Maybe you’ve automated a deployment, wrangled some log files, or stitched together a few commands to save time. But as your scripts grow, something changes. What started as a clean 20-line helper becomes a 200-line sprawl. Functions call functions that modify global variables. You copy-paste code between scripts because extracting shared logic feels harder than it should be. The script works, but it’s fragile, and you’re the only person who can maintain it.
