Shiv
by SilverAndro
Shiv is a Quilt mod that rewrites other mods' code through mixins, aimed at modders and developers rather than general players.
What it does
Shiv works by changing or removing mixins that other mods apply to Minecraft, and where needed it swaps them for code that fits better. The author describes its purpose as collection hacks and compatibility repair, for cases where two mods would otherwise conflict. Some of its tools are built for the Quilt loader developer workflow.
Shiv runs on client and server, so the server and every player need it. It is published only for Quilt, across three game versions: 1.18.2, 1.19.2 and 1.19.4, with 1.0.1 for 1.19.4 as the latest file. It needs a full JDK to run during development, while a JRE is enough for normal play and the mod attaches through the Java agent API. The source code and issue tracker are public, and the license is custom and not open source.
Key features
Mixin removal
Individual mixins applied by other mods can be removed, so their changes no longer take effect in the game.
Mixin condition control
The shouldApplyMixin condition can be overridden, which lets a mixin be switched off for specific cases.
Injection overwriting
Existing injections into Minecraft code can be replaced with new ones, which changes how a method behaves.
Bytecode transformations
Arbitrary transformations of compiled class bytecode can be applied while the game loads.
Compatibility
Latest build for each game version and loader.
Only full game releases are shown. This mod publishes no snapshot builds.
Use cases
Resolving mod conflicts
A modder can disable or replace a conflicting mixin from another mod so that two mods can share the same game code.
Who it’s for: Shiv suits mod developers and advanced users who debug mixin conflicts. Players looking for new content will not find it here.
