-# 用户偏好 RAG 库（待定）
+# 用户偏好库 / 文风库
 
-> 状态：**未实现**。先记设计共识与未决项，尤其 RAG 插入点。
 
-## 已对齐
 
-### 写库（学习，不改游玩上下文）
+> 状态：**节点绑定（无 RAG）**。偏好与文风分库；创作节点声明 `libraries` 后注入，库空跳过。
 
-- 累计对话轮次 ≥ **10**（可在设置中改）后，尝试从最近对话**总结**用户偏好。
-- 弹出**审核卡**：通过 / 编辑后通过 / 合并到已有 / 跳过。
-- 通过后才写入全局偏好库；支持**去重**与**更新已有条目**。
-- 「随机插一条」= 往库里记候选，**不**修改当前轮 prompt。
 
-### 读库（仅创建期）
 
-- 根据用户输入 **Boss 直聘式**召回匹配条目（卡片点选）。
-- 选中结果收成**本局固定上下文**（`resident_context` / 叙事指南合并），不在游玩期动态插入。
+## 两库
 
-### 条目形状（草案）
 
-- `id`, `title`, `kind`（style|taboo|tone|format|other）
-- `keys[]`（检索用）, `content`, `mount[]`, `always_on?`
-- `source`（manual|learned）, `status`（active|archived）
 
-## 未决：RAG 怎么插
+| 库 | 存盘 | 绑定节点 | 注入 |
 
-当前仓库**无 embedding / 向量检索**。需先定插入架构，再写代码。
+|----|------|----------|------|
 
-| 选项 | 做法 | 优点 | 风险 |
-|------|------|------|------|
-| A. 关键词召回 | `keys` + 标题匹配用户输入 | 零依赖、快落地 | 召回弱 |
-| B. 创建期 LLM 选条 | 把库摘要交给 design-flow 一步选 | 与现有编排一致 | token、不稳定 |
-| C. 本地 embedding | 条目向量化 + 相似度 Top-K | 真 RAG | 新依赖、索引维护 |
-| D. 混合 | always_on + 关键词粗筛 +（可选）embedding 精排 | 可渐进 | 实现稍复杂 |
+| **文风库** `style-packs` | `~/.writing-agent/style-packs.json` | 叙事指南、叙事指南与故事推进 | 【文风库 · 可选用】 |
 
-**读库插入落点（创建期）候选：**
+| **偏好库** `preferences` | `~/.writing-agent/preferences.json` | 用户需求 | 【偏好库 · 可选用】 |
 
-1. `设计.用户偏好.选用集` fragment → `refine` 合并进 `resident_context` / 叙事 `情境备用` / `绝对禁忌`
-2. 仅 `resident_context[]`，不经过叙事指南
-3. 新设计步「用户偏好」专产选用集
 
-**写库触发落点候选：**
 
-1. `session-manager` 回合末计数 + 调 summarize API
-2. 独立 `PreferenceService` + `/api/preferences/*`
-3. 审核 UI 挂在 `SessionView.preferenceReview`
+## 读写
 
-## 建议实现顺序（定好 RAG 后再做）
 
-1. 库 store + 手写样例条目
-2. 设置项 `preferenceReviewEveryTurns`（默认 10）
-3. 读库：关键词召回 + Boss 卡片 + 选用集 tag
-4. `refine` 合并选用集 → 固定上下文
-5. 写库：轮次触发 + 总结 + 审核 + 去重写回
-6. （可选）embedding RAG
 
-## 相关现有基建
+| 阶段 | 行为 |
+
+|------|------|
+
+| **库页** | 顶栏「库」：手写 CRUD + LLM 提取入库 |
+
+| **创作节点** | design-step / 对话落盘按 `libraries` 注入目录；节点选用写入本局产物 |
+
+| **开玩** | **不再**全量自动摊偏好；靠产物 `设计.用户需求` / `设计.叙事指南*` 挂载 |
+
+| **游玩** | 每隔 N 回合采集偏好候选（设置项）；收下写入全局偏好库 |
+
+
+
+## 偏好条目形状
+
+
+
+- `id`, `content`, `status`（active|archived）, `createdAt`, `updatedAt`
+
+
+
+## 文风包形状
+
+
+
+- `id`, `name`, `content`, `samples?`, `status`, `createdAt`, `updatedAt`
+
+
+
+## 设置
+
+
+
+- `preferenceCollectEveryTurns`：采集间隔（默认 10；0=关）
+
+- 设置页「用户偏好」：只留间隔；CRUD 在库页
+
+
+
+## API
+
+
+
+- `GET/POST /api/preferences`；`PUT/DELETE /api/preferences/:id`
+
+- `POST /api/preferences/extract`

+- `GET/POST /api/style-packs`；`PUT/DELETE /api/style-packs/:id`
+
+- `POST /api/style-packs/extract`

+- `POST /api/sessions/:id/preferences/review`
+
+
+
+## 实现
+
+
+
+- `src/libraries/registry.ts` — 库注册 + `formatBoundLibrariesForPrompt`
+
+- `src/style-pack/` — 文风库
+
+- `src/preference/` — 偏好库 + extract
+
+- `skills/.../modules/user-requirements/` — 用户需求节点
+
+- `web/libraries.html` — 库页

-- 常驻：`src/skills/resident-context.ts`，`设计.worker集.resident_context`
-- 投影排序：`context-order` inserts
-- 叙事写法档：`设计.叙事指南` → `情境备用`
-- 设置：`src/config/settings.ts`
-- 无游玩期上下文注入需求（与 `context-assembly.md` 一致）
