+## 2025-12-14 - [Bash Script UX]
+**Learning:** CLI tools in this repo are heavily macOS-dependent but lack compatibility checks, leading to confusing errors on other systems.
+**Action:** When working on shell scripts, always add `command -v` checks or OS detection to provide clear feedback instead of raw errors.
