# US-004: Automatically replace broken tools

As a **player**, I want an equivalent tool moved into my hand when my current tool breaks so that I can continue working without searching my inventory.

## Acceptance criteria

- [x] When a player's main-hand tool breaks, the plugin searches the player's inventory for a replacement.
- [x] A replacement must have the same tool type and material as the broken tool; for example, a diamond pickaxe replaces only a diamond pickaxe.
- [x] Eligible replacements may come from the main storage inventory or another hotbar slot.
- [x] The replacement is moved into the currently selected hotbar slot.
- [x] Existing durability, enchantments, custom names, persistent data, and other metadata on the replacement are preserved.
- [x] No unrelated item is moved when an equivalent replacement is unavailable.
- [x] Off-hand tool breakage does not replace the main-hand item.
- [x] Cancelled damage or break events do not trigger replacement.
- [x] Automated tests cover matching, unavailable replacements, hotbar and main-storage candidates, metadata preservation, and off-hand behavior.
