Unity Project Hygiene Tool is an editor extension for safely identifying unused assets, protecting scene dependencies and creating recoverable external backups in growing Unity projects.
It analyzes the reference graph rather than deleting files blindly, exports assets with their .meta data and produces auditable reports with one-step restoration.
Together with VR QuickTest, Unity HandBrake Video Optimizer and Asset Usage Checker, it forms part of my developer tool ecosystem for faster everyday production.
