Realism Tweaks Tag Lib is a small library mod that provides a set of shared block and item tags used by the Realism Tweaks
It doesn’t add any gameplay features on its own – instead, it defines consistent tag groups (e.g. blocks that can be broken by falling anvils, fragile glass variants, etc.) that other mods can reference to ensure compatibility and maintainability.
