Illegal weapons and forbidden items are the confirmed categories
Those are the exact broad categories named in the Roblox experience description. The wording does not establish a complete list, value table, scanner formula, or rule for every specific object.
In the core game loop, you search inmates and visitors for contraband. When the current interface identifies something, use the prompts shown in your session. A screenshot or third-party list can help you recognize the theme of the task, but it should not replace the live inspection result.
