Don't YOLO your file system
Summary
The jai tool provides a lightweight containment boundary for AI agents on Linux, preventing unauthorized access to the user's home directory by using a copy-on-write overlay. It emphasizes safety by discouraging one-line installers and AI-generated commands that touch real homes, offering three isolation modes (Casual, Strict, Bare) to fit different workflows. It positions jai as a free, simpler alternative to full containers and highlights real-world incidents of AI tools causing data loss.
