Inspect a .unitypackage against your project before importing it, decide what comes in, and import with colliding GUIDs remapped.

The hazard it exists for: a package claiming a GUID that already belongs to a different asset in your project. The paths differ, so Unity's own import dialog looks completely clean while existing references get silently re-pointed.

Usage

Features

Diffs a .unitypackage against the current project before anything is written
Flags GUID collisions and remaps them on import instead of overwriting
Audits scripts inside the package
Shows what each entry would land on, as a tree
Drag a .unitypackage straight into the window, or double-click one, or use

Choose Package

Export a password-protected .unitypackage.enc; opening one prompts for the

password before anything is read. This is a distribution gate, not DRM - the ciphertext and the code that decrypts it both ship in the file, so it only stops "double-click and it just opens," not a determined recipient. Authentication is pluggable (see IUpkgAuthMethod); password is the only method implemented today.
