Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# 03 — 物品开发

> 适用版本：Fabric 1.14.4
> Yarn：[`Item.mapping`](https://github.com/FabricMC/yarn/blob/1.14.4/mappings/net/minecraft/item/Item.mapping)、[`FoodComponent.mapping`](https://github.com/FabricMC/yarn/blob/1.14.4/mappings/net/minecraft/item/FoodComponent.mapping)、[`ToolMaterial.mapping`](https://github.com/FabricMC/yarn/blob/1.14.4/mappings/net/minecraft/item/ToolMaterial.mapping)

## 约束

### 核心原则

- 物品必须在 `Registry.register(Registry.ITEM, id, item)` 中注册
- mod ID 使用 `new Identifier(MOD_ID, "name")` 构造
- **禁止**通过 `new Item()` 后不注册的方式使用
- Yarn `Item.Settings` 默认 `maxCount(64)`、`maxDamage` 为 0（不可损坏）。不要写 MCP `Item.Properties` / `maxStackSize`，也不要说默认耐久是 `Integer.MAX_VALUE`

---

## Decision Flow

### Decision: 选择物品类型

```
IF 只是手持物品（无特殊行为）
  → new Item(new Item.Settings())

IF 是工具（剑/镐/斧/铲）
  → SwordItem / PickaxeItem / AxeItem / ShovelItem（镐斧铲的公共父类是 MiningToolItem）
  → 不要 DiggerItem（那是后期 Yarn 名）

IF 是盔甲
  → 使用 ArmorItem + ArmorMaterial

IF 是食物
  → Item.Settings.food(FoodComponent)

IF 是可耐久工具
  → Settings.maxDamage(...)；工具材质实现 ToolMaterial（含 getRepairIngredient）

IF 需要自定义行为
  → 继承 Item 并重写 use()、useOnBlock()、useOnEntity() 等
```

How to install

The exact contents, by fingerprint

mdr add guguzea/mc-ai-coding-assistant-tool/fabric/1.14.4/.cursor/rules/03-item.mdc@sha256:0ab0f6c0a1ed7035

The line at the top of this page pins the label git:20260819.ca99162, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
