    No harmful code found in the projects we checked

    We checked 101 of its 103 projects, without running them.

    We have not checked the files in the pack itself yet (settings, scripts).

    Why we show this: a modpack installs the files of its mods, and each mod runs on your computer like any program. Our checks look for known signs of harm. They cannot prove that a file is harmless. In the grade: a modpack has no grade of its own, and each mod's result counts in that mod's grade.

    4 mods send something about you

    We read the code of 100 of its 102 mods, without running it.

    Why we show this: a modpack runs the code of its mods, and a mod can send things about you over the internet, like your player name or your login. Contacting an address to check for updates or download files sends nothing about you. Not in the grade: sending data can be normal for what a mod does.

    AI

    AI used in 3 of the 49 mods we checked

    We found an AI tool in them, or their authors declared AI content.

    53 mods are not checked yet.

    No sign so far that AI was used to make the pack itself

    We looked for AI tools in its texts and found none.

    We have not read its files and images yet.

    Why we show this: some players and servers avoid projects made with AI, and AI in the game can send what you write to an online service. Not in the grade: using AI does not tell whether a project works well or is kept up to date.
