What is cslol-manager?

CSLoL Manager is a Windows tool for players of League of Legends, the online multiplayer game, that lets them load custom, unofficial skins for their champions and swap other visual and gameplay elements inside the game client. Skins in League of Legends are cosmetic outfits for characters, and this tool lets a player use fan made or modified versions of them instead of only the official ones sold by the game's publisher, Riot Games. Beyond just skins, the tool also includes features to change which champion model is shown, swap models between characters, an auto queue feature that can automatically join matchmaking, a dodge assistant, in game overlays, and some replay related tools. It presents these through its own desktop application with a graphical interface for managing and editing the loaded modifications, shown in the project's screenshots as a main window plus separate views for editing mod info and managing files. To use it, a player downloads a prebuilt zip file from the project's releases page, extracts it, and runs the manager executable as an administrator, then logs into their League of Legends account and turns on whichever features they want before loading custom skins. The README is direct about the risk involved: this is an unofficial third party tool that is not affiliated with or endorsed by Riot Games, and using it may violate Riot's terms of service, which the developers say can lead to account restrictions or permanent bans. The README states this plainly as a caution and tells users the choice to use it is at their own risk. The underlying project is written in C++, though the README itself does not go into technical detail about how the skin loading works internally.
