📋 About This Mod
This is the Compatibility Framework. Split off from BG3 Community Library, this mod provides an API and easy JSON Configuration-based compatibility loader for other mods to use improve compatibility. Initially designed for Subclass Compatibility, the Framework has API endpoints that Script-Extender Enabled mods can hook into to insert values into Races, Progressions/Feats and Spell/Skill/PassiveLists at Runtime. What this means is that a mod author can inject their mod's data into existing Progressions, Feats, Races, or Lists without overwriting data, allowing for total compatibility. If you want to know which mods are currently supported, check out this list.
The BG3 Compatibility Patcher and Spell List Combiner are two alternatives, that take different approaches to handling compatibility with Progressions and Lists.
Contributing
The Compatibility Framework makes it easy to set mods that work with Progressions or Lists up for compatibility with other mods that alter the same things. You can utilize the Framework's API (Template Provided), or add a small amount of code to a single file. To find out how, check out our Wiki page.
Our Wiki on GitHub has useful documentation on using the Compatibility Framework, both via its API and its JSON Configuration loader methods. For quick links to documentation on specific parts of the Framework, see this list:

Installation
This mod works with Baldur's Gate 3 Mod Manager, and possibly Vortex and Manual Installations. BG3 Mod Managers is by far the simplest method, and as such is recommended one.
