The vanilla durability bar is vague — is that pickaxe at 30% or 3%? DurabilityPing puts the exact number right above your hotbar: 1234 / 1561, updated live as you mine.
When durability drops under 10%, the number turns red and a "pling" sound plays once, so you notice before the tool shatters mid-vein. Swap tools and the warning resets automatically.
Client-side only. No config, no mixins, no networking.
Requires Fabric Loader 0.19+ and Fabric API for Minecraft 26.2.
