which files work?
Places (.rbxl, .rbxlx) and models (.rbxm, .rbxmx), binary or XML. In Studio, use File → Save to File As, or right-click a model and Save to File. Rojo builds work too, and Studio's autosaves live in %LOCALAPPDATA%\Roblox\RobloxStudio\AutoSaves.
The demo place is made up: physics crates, glass bridges, shadowed street lamps, and a "free model" tree with fake backdoor patterns for the scan to find.
$ stat
most common classes
$ likely lag sources
$ script scan
$ explore
Pick an instance in the tree, a finding, or a script issue.
The checks are heuristics, not verdicts: a flagged part may be unanchored on purpose, and a script with no flagged patterns isn't proven safe. Comments and the inside of strings are skipped, so only real code is matched.
