Swap
Swap is a Fabric client utility that replaces a tool about to break with another matching tool from the inventory.
What it does
When a held tool is nearly worn out, Swap watches its durability and, after the tool drops to a set level, moves a fresh tool of the same kind into the hand. A Diamond Pickaxe that breaks can fall back to an Iron Pickaxe if one is available. The same logic applies to building blocks: a stack of Spruce Planks that runs out can be replaced by Oak Planks. The mod is client-side only, so players install it alone and servers do not need it. It is released under CC0 1.0 Universal and is open source, with public source code and an issue tracker.
Key features
Durability monitoring
Swap tracks the durability of the held tool and reacts before it shatters, so an item is not lost mid-task.
Tool fallback
When no matching tool is left, a lower-tier tool of the same type is selected from the inventory if one is present.
Block stack replacement
An emptied block stack is refilled from a compatible block type, such as Oak Planks for Spruce Planks.

What the author says
Never accidentally destroy a high level Mending tool again. It constantly monitors your item's durability and If the tool drops to 2 durability, it automatically swaps it for a fresh tool from your inventory before it shatters.
