To Avoid Paying $120, I Turned a Computer Cleaner into an Open-Source Skill

为了不花那120刀，我把电脑清理软件做成了开源skill

The author open-sourced a cross-platform AI cleaning skill for Mac and Windows, generating interactive HTML reports from file scans; in a test, it freed nearly 120GB, compared with CleanMyMac identifying 15.8GB.

Why it matters: This is not a platform-level release, but HKR-H/K/R all land through the $120 replacement hook, concrete scan/report mechanism, and 120GB test result. It fits the practical open-source tool band near the featured threshold.
