PackCheck

Check your gear before heading out. PackCheck is a read-only, client-side inventory readiness checklist for Minecraft. Choose an activity and see what you have and what is missing.

Features

• Activity templates for Mining, Nether, End, Exploration, Building, Farming and PvP.
• Create, rename, favorite and customize loadouts with an item icon picker.
• A live HUD with Ready, Partially Ready and Missing Items states.
• Rules for quantities, alternative items and tags, equipped armor, offhand, enchantments, remaining durability and exact component values.
• Optional checks of carried shulker contents; disabled by default.
• Separate profiles per world or server, plus JSON import and export.

Installation

Install Fabric Loader and the matching Fabric API. Put the PackCheck jar for your exact Minecraft version in your client mods folder. No server installation is needed.

• Minecraft 26.3: Java 25, Fabric Loader 0.19.5+, matching Fabric API.
• Minecraft 1.21.11: Java 21+, Fabric Loader 0.18.4+, Fabric API 0.141.6+ for 1.21.11.

Press K to open the editor. Rebind it in Options > Controls > PackCheck. Assign the HUD toggle key or use the editor HUD button.

Scope

PackCheck never moves items or changes your inventory. It checks client-visible data. It does not inspect nearby chests, infer ender chest contents, or integrate with storage mods. Carried shulker checks require content data actually supplied to the client.

The two supported Fabric builds passed real client smoke tests. Live multiplayer, inventory-overhaul compatibility and full narrator accessibility remain unverified. Older Minecraft versions, Forge and NeoForge are not supported.
