- Mods2.4kA mod changes the game itself. It needs something to load it, it may need other mods first, and it only works on the versions its author built it for.
- Libraries50A library provides shared code other mods depend on rather than any content of its own. It is required, not optional, whenever something else lists it as a dependency.
- Frameworks8A framework is modding infrastructure rather than content: an API, injector or utility that other mods run on top of, or that helps you install, patch or manage them.

Why Halo: The Master Chief Collection mods break
A mod is compiled against one version of a game. When the game updates, anything that reached into the parts that moved stops working, and it usually stops working silently rather than with a message that explains itself.
That is what the table above counts. It is not a guess: each row is a mod the community has reported as broken by that specific release. The number is a fair measure of how disruptive an update was, and it is the reason people delay updating a game they have modded heavily.
Common questions
Does IndexGG host Halo: The Master Chief Collection mods?
No, and it never will. Every download link points at the author's own page on Nexus, GitHub, CurseForge or wherever they published it. We index the ecosystem; the files stay with the people who made them.
Where does the compatibility data come from?
From the communities that maintain it in the open, not from guesswork. Each claim carries how it is known, so a reported breakage is never presented as though the author said it.
Why is a mod listed as broken when it works for me?
Compatibility depends on your exact game version and the rest of your load order. A mod marked as broken in one release may work fine on an older one, which is exactly why the version is recorded next to the claim rather than a bare yes or no.
