What is -creamapi-dlc-unlocker-for-cities-skylines-steam-unlock-all-dlcs-free-?

This repository is a tool that claims to unlock all paid downloadable content for the city building game Cities: Skylines on Steam, using a method called CreamAPI. Downloadable content, or DLC, refers to extra game content, expansion packs, themed building sets, and radio stations, sold separately from the base game. The README explains that CreamAPI works by creating what it calls a fake Steam DLC manifest, which tricks the game into behaving as if the player owns all available DLC. It describes this as a client side only method that does not modify the game's core files. The README states there is no VAC ban risk and that the provided files are pre configured with a file called cream_api.ini listing all DLC identifiers. It also states that once unlocked, the game treats the player as a DLC owner, allowing access to Steam Workshop assets that normally require owning specific expansions. DLC content the README lists includes expansions such as After Dark, Snowfall, Natural Disasters, Mass Transit, Green Cities, Parklife, Industries, Campus, Sunset Harbor, Airports, and Plazas and Promenades, plus content creator packs including Art Deco, High Tech Buildings, and Modern Japan, and all radio station DLCs. Installation is described as downloading an archive, temporarily disabling antivirus software, running Loader.exe as administrator, and pressing INSERT to open a menu. System requirements are Windows 10 or 11 with Cities: Skylines installed and 20 MB of free space. The repository has no listed programming language, and running an unverified executable with antivirus disabled carries real risk regardless of the no ban claim.
