TradeWatch

A wishlist holds the enchantments of interest, each with a maximum emerald price set per level from 1 to 64. Entries use Minecraft registry identifiers, and the search field accepts short names such as eff or mend to select an enchantment. Prices are configured per enchantment level, so Efficiency IV can be watched at 15 emeralds while Efficiency V is watched at 32. When a matching offer appears on a merchant screen, the matching rows turn green, a vanilla ping sounds once per opened screen, and a center-screen panel reports the result. Only enchanted-book offers are checked, and the comparison uses the actual emerald cost shown on the offer, including any discounts.

The mod never clicks, rerolls, trades, interacts with blocks or breaks lecterns. It only reads and highlights offers, so the purchase stays with the player. Entries that refer to registry identifiers no longer present are removed safely after registry synchronization. The configuration screen opens with the G key by default, and the key can be rebound in Minecraft Controls. Mod Menu is optional and adds a Configure button. The mod requires Fabric Loader and Fabric API and is open source under the MIT License.
