+### ToolDef 字段说明
+
+`RegisterTool` 的 `def` 参数类型为 `sdk.ToolDef`，包含以下字段：
+
+| 字段 | 类型 | 说明 |
+|------|------|------|
+| `Name` | `string` | 工具名，建议插件名前缀避免冲突 |
+| `Description` | `string` | 工具描述，LLM 据此选择调用 |
+| `Parameters` | `map[string]interface{}` | JSON Schema 格式参数定义 |
+| `NoMemory` | `bool` | 默认为 `false`；设为 `true` 时输出不参与向量/jieba/蒸馏计算（原文保留） |
+| `Cleaner` | `func(string) string` | 可选，输出进入计算层前的清洗函数（如 JSON 提取 `.content`） |
+
+`NoMemory` 和 `Cleaner` 的详细设计意图参见核心仓 `docs/zh/PLUGIN_DEV.md`。
+
 ### New 构造函数
 
 `New()` 由内核在加载插件时调用，插件开发者无需手动构造 PluginSDK：

 - `SubjectType` — subject type
 - `ObjectType` — object type
 
+### ToolDef Field Reference
+
+The `def` parameter of `RegisterTool` is of type `sdk.ToolDef`, with the following fields:
+
+| Field | Type | Description |
+|-------|------|-------------|
+| `Name` | `string` | Tool name, use plugin name prefix to avoid conflicts |
+| `Description` | `string` | Tool description, LLM uses this for tool selection |
+| `Parameters` | `map[string]interface{}` | JSON Schema parameter definition |
+| `NoMemory` | `bool` | Default `false`; when `true`, output skips vector/jieba/distill computation (original text preserved) |
+| `Cleaner` | `func(string) string` | Optional, filters output before computation layer (e.g., extract `.content` from JSON) |
+
+For detailed design rationale of `NoMemory` and `Cleaner`, see `docs/en/PLUGIN_DEV.md` in the core repository.
+
 ### New Constructor
 
 `New()` is called by the kernel when loading a plugin. Plugin developers do not need to construct PluginSDK manually:
