 ## 记忆系统
 
 你每次会话都是全新的，记忆文件让你保持连续性：
 
-### 📝 每日记忆：`memory/YYYY-MM-DD.md`
-- 原始的对话日志
-- 记录当天发生的事情
-- 如果 `memory/` 目录不存在，创建它
-
 ### 🧠 长期记忆：`MEMORY.md`
-- 你精选的记忆，就像人类的长期记忆
-- **仅在主会话中加载**（与用户的直接聊天）
-- **不要在共享上下文中加载**（群聊、与其他人的会话）
-- 这是为了**安全** - 包含不应泄露给陌生人的个人上下文
-- 记录重要事件、想法、决定、观点、经验教训
-- 这是你精选的记忆 - 精华，而不是原始日志
-- 用 `edit` 工具追加新的记忆内容
+- 你精选的记忆索引，每次会话启动时**自动加载**到上下文中
+- 记录核心事实、偏好、决策、重要人物、教训
+- 保持精简（< 200 行），是精华索引而非原始日志
+- 用 `edit` 工具追加或修改
+
+### 📝 每日记忆：`memory/YYYY-MM-DD.md`
+- 当天的事件、进展、笔记
+- 原始对话日志的沉淀
 
 ### 📝 写下来 - 不要"记在心里"！
-- **记忆是有限的** - 如果你想记住某事，写入文件
+- **记忆是有限的** - 想记住的事就写入文件
 - "记在心里"不会在会话重启后保留，文件才会
 - 当有人说"记住这个" → 更新 `MEMORY.md` 或 `memory/YYYY-MM-DD.md`
 - 当你学到教训 → 更新 RULE.md 或相关技能
-- 当你犯错 → 记录下来，这样未来的你不会重复，**文字 > 大脑** 📝
+- 当你犯错 → 记录下来，**文字 > 大脑** 📝
 
 ### 存储规则
 
 当用户分享信息时，根据类型选择存储位置：
 
-1. **你的身份设定 → AGENT.md**（你的名字、角色、性格、交流风格——用户修改时必须用 `edit` 更新）
-2. **用户静态身份 → USER.md**（姓名、称呼、职业、时区、联系方式、生日——用户修改时必须用 `edit` 更新）
-3. **动态记忆 → MEMORY.md**（爱好、偏好、决策、目标、项目、教训、待办事项）
+1. **你的身份设定 → AGENT.md**（名字、角色、性格、风格）
+2. **用户静态身份 → USER.md**（姓名、称呼、职业、联系方式、生日）
+3. **动态记忆 → MEMORY.md**（偏好、决策、目标、教训、待办）
 4. **当天对话 → memory/YYYY-MM-DD.md**（今天聊的内容）
+5. **结构化知识 → knowledge/**（见下方知识系统）
+
+## 知识系统
+
+知识库 `knowledge/` 是你持续积累的结构化知识。与记忆不同，知识是经过整理和编译的，有明确的主题和交叉引用。
+
+### 自动写入（不要询问，直接写入）
+
+当对话中产生了有沉淀价值的知识——无论是用户分享的资料、讨论的结论、学到的概念、还是重要的决策——你**必须**在回复的同时主动写入知识库，**无需问用户"要不要存到知识库"**。
+
+**关键原则**：学完就记是你的本能，不要征求确认。回复中可以顺带告知"已存入知识库"。
+
+### 目录组织
+
+子目录结构**不是固定的**，由你根据实际内容自主决定：
+- **首次写入时**：先读 `knowledge/index.md`，如果已有分类则延续；如果为空，根据内容选择合适的目录名
+- **默认建议**：按信息类型组织（例如sources/、concepts/、entities/、analysis/），如果用户有明确的分类偏好（例如按领域 work/、life/、tech/ 等），则按用户要求调整
+- **保持一致性**：同一用户的知识库应保持统一的组织风格
+
+### 交叉引用
+
+知识的核心价值在于**关联**。每个页面都应通过 markdown 链接引用相关页面，构建知识网络：
+- 提到已有页面的概念时，添加 `[概念名](../category/page.md)` 链接
+- 新建页面时，检查是否有已有页面应该反向链接到新页面
+- **只链接已存在的页面**——不要引用尚未创建的页面。如果某个概念值得单独建页，先创建该页面再添加链接
+
+### 索引维护
+
+每次创建或更新知识页面后，**必须同步更新** `knowledge/index.md`。
+索引格式：每行一个 `[标题](路径) — 一句话摘要`，按分类分组，不要用表格。
+详细操作规范见技能 `knowledge-wiki`。

-## 2. Task Planning and Tool Use
+## 2. Personal Knowledge Base
+
+> The knowledge base system enables the Agent to continuously accumulate and organize structured knowledge. Unlike memory which records along a timeline, the knowledge base is organized by topics, transforming articles, conversation insights, and learning materials into interconnected Markdown pages that form a continuously growing knowledge network.
+
+The Agent automatically organizes valuable information from conversations into knowledge pages, maintaining cross-references and indexes. The Web console provides document browsing and knowledge graph visualization. Knowledge is stored in `~/cow/knowledge/` within the workspace.
+
+- **Auto-organization**: The Agent autonomously extracts and organizes structured knowledge during conversations, maintaining indexes and cross-references
+- **Knowledge graph**: Automatically builds a knowledge graph from cross-references between pages, with interactive graph visualization in the Web console
+- **Chat integration**: Knowledge document links referenced in Agent replies can be clicked directly in the Web console for viewing
+- **CLI management**: Use `/knowledge` commands to view stats, browse directory, and toggle the feature with `/knowledge on|off`
+
+See [Personal Knowledge Base](/en/knowledge) for details.
+
+## 3. Task Planning and Tool Use
 
 Tools are the core of how the Agent accesses operating system resources. The Agent intelligently selects and invokes tools based on task requirements, performing file read/write, command execution, scheduled tasks, and more. Built-in tools are implemented in the project's `agent/tools/` directory.
 
 **Key tools:** file read/write/edit, Bash terminal, browser, file send, scheduler, memory search, web search, environment config, and more.

+title: Personal Knowledge Base
+description: CowAgent personal knowledge base — structured knowledge accumulation, automatic organization, and knowledge graph
+---
+
+The personal knowledge base is the Agent's long-term structured knowledge store, saved in the `knowledge/` directory within the workspace. Unlike memory, which is organized by timeline, the knowledge base organizes content by topic — articles, conversation insights, and learning materials are structured into interlinked Markdown pages, forming a continuously growing knowledge network.
+
+## Core Concepts
+
+### Knowledge vs Memory
+
+| Dimension | Knowledge Base (knowledge/) | Long-term Memory (memory/) |
+| --- | --- | --- |
+| Organization | By topic, interlinked | By timeline, dated files |
+| Writing | Agent actively structures content | Auto-summarized on context trimming |
+| Content | Refined, structured knowledge | Raw conversation summaries |
+| Use cases | Study notes, tech docs, project knowledge | Conversation history, event records |
+
+### Directory Structure
+
+```
+~/cow/knowledge/
+├── index.md          # Knowledge index, entry point for all pages
+├── log.md            # Change log, records each write
+├── concepts/         # Conceptual knowledge
+│   └── machine-learning.md
+├── entities/         # Entity knowledge (people, orgs, tools)
+│   └── openai.md
+└── sources/          # Source knowledge (articles, papers)
+    └── llm-wiki.md
+```
+
+The directory structure is flexible — the Agent automatically creates appropriate category directories based on actual content. Users can also customize the organization.
+
+## Automatic Organization
+
+Knowledge writing is an autonomous Agent behavior, triggered in these scenarios:
+
+- **User shares an article or document** — The Agent automatically extracts key information and creates a structured knowledge page
+- **Conversation produces valuable conclusions** — The Agent organizes insights into knowledge pages and links them to existing knowledge
+- **User explicitly requests organization** — Users can guide the Agent to organize and update knowledge through conversation
+
+Each knowledge page includes cross-reference links to related pages, gradually building a knowledge graph.
+
+## Knowledge Retrieval
+
+The Agent can retrieve knowledge during conversation through:
+
+- **Index lookup** — Quickly locate relevant pages via `knowledge/index.md`
+- **Semantic search** — Search knowledge content via the `memory_search` tool
+- **Direct read** — Read specific knowledge files via the `memory_get` tool
+
+## Web Console
+
+The web console provides a dedicated "Knowledge" module with:
+
+- **Document browsing** — Tree-style directory structure, searchable and collapsible, click to view content
+- **Knowledge graph** — D3.js force-directed graph visualizing relationships between knowledge pages
+- **Chat integration** — Knowledge document links referenced in Agent replies are clickable for direct navigation
+
+## CLI Commands
+
+Manage the knowledge base with the `/knowledge` command:
+
+| Command | Description |
+| --- | --- |
+| `/knowledge` | Show knowledge base statistics |
+| `/knowledge list` | Display file directory as a tree |
+| `/knowledge on` | Enable the knowledge base feature |
+| `/knowledge off` | Disable the knowledge base feature |
+
+## Configuration
+
+| Parameter | Description | Default |
+| --- | --- | --- |
+| `knowledge` | Whether to enable the personal knowledge base | `true` |
+| `agent_workspace` | Workspace path; knowledge is stored under the `knowledge/` subdirectory | `~/cow` |

+title: パーソナルナレッジベース
+description: CowAgent のパーソナルナレッジベース — 構造化された知識の蓄積、自動整理、ナレッジグラフ
+---
+
+パーソナルナレッジベースは、Agent の長期的な構造化知識ストレージで、ワークスペースの `knowledge/` ディレクトリに保存されます。タイムラインで整理されるメモリとは異なり、ナレッジベースはトピック別にコンテンツを整理します。記事、会話のインサイト、学習資料が相互リンクされた Markdown ページとして構造化され、継続的に成長するナレッジネットワークを形成します。
+
+## コアコンセプト
+
+### ナレッジ vs メモリ
+
+| 次元 | ナレッジベース（knowledge/） | 長期記憶（memory/） |
+| --- | --- | --- |
+| 整理方法 | トピック別、相互リンク | タイムライン順、日付ファイル |
+| 書き込み | Agent が能動的に構造化 | コンテキストトリミング時に自動要約 |
+| コンテンツ | 精製された構造化知識 | 生の会話要約 |
+| 用途 | 学習ノート、技術ドキュメント、プロジェクト知識 | 会話履歴、イベント記録 |
+
+### ディレクトリ構造
+
+```
+~/cow/knowledge/
+├── index.md          # ナレッジインデックス、全ページのエントリポイント
+├── log.md            # 変更ログ、各書き込みの記録
+├── concepts/         # 概念的な知識
+│   └── machine-learning.md
+├── entities/         # エンティティ知識（人物、組織、ツール）
+│   └── openai.md
+└── sources/          # ソース知識（記事、論文）
+    └── llm-wiki.md
+```
+
+ディレクトリ構造は柔軟です — Agent は実際のコンテンツに基づいて適切なカテゴリディレクトリを自動作成します。ユーザーが整理方法をカスタマイズすることも可能です。
+
+## 自動整理
+
+ナレッジの書き込みは Agent の自律的な動作で、以下のシナリオでトリガーされます：
+
+- **ユーザーが記事やドキュメントを共有** — Agent が自動的にキー情報を抽出し、構造化されたナレッジページを作成
+- **会話から価値ある結論が生まれた場合** — Agent がインサイトをナレッジページに整理し、既存の知識とリンク
+- **ユーザーが明示的に整理を要求** — ユーザーは会話を通じて Agent にナレッジの整理・更新を指示可能
+
+各ナレッジページには関連ページへの相互参照リンクが含まれ、ナレッジグラフを段階的に構築します。
+
+## ナレッジ検索
+
+Agent は会話中に以下の方法でナレッジを検索できます：
+
+- **インデックス参照** — `knowledge/index.md` で関連ページを素早く特定
+- **セマンティック検索** — `memory_search` ツールでナレッジコンテンツをセマンティック検索
+- **直接読み取り** — `memory_get` ツールで特定のナレッジファイルを読み取り
+
+## Web コンソール
+
+Web コンソールには専用の「ナレッジ」モジュールがあり、以下をサポートします：
+
+- **ドキュメント閲覧** — ツリー形式のディレクトリ構造、検索・折りたたみ可能、クリックでコンテンツ表示
+- **ナレッジグラフ** — D3.js フォースダイレクテッドグラフによるナレッジ間の関係を可視化
+- **チャット連携** — Agent の返信で参照されたナレッジドキュメントリンクはクリックで直接ナビゲーション
+
+## CLI コマンド
+
+`/knowledge` コマンドでナレッジベースを管理：
+
+| コマンド | 説明 |
+| --- | --- |
+| `/knowledge` | ナレッジベースの統計情報を表示 |
+| `/knowledge list` | ファイルディレクトリをツリー形式で表示 |
+| `/knowledge on` | ナレッジベース機能を有効化 |
+| `/knowledge off` | ナレッジベース機能を無効化 |
+
+## 設定
+
+| パラメータ | 説明 | デフォルト |
+| --- | --- | --- |
+| `knowledge` | パーソナルナレッジベースの有効/無効 | `true` |
+| `agent_workspace` | ワークスペースパス、ナレッジは `knowledge/` サブディレクトリに保存されます | `~/cow` |

+title: 个人知识库
+description: CowAgent 的个人知识库系统 — 结构化知识沉淀、自动整理与知识图谱
+---
+
+个人知识库是 Agent 的长期结构化知识存储，保存在工作空间的 `knowledge/` 目录下。与按时间线组织的记忆不同，知识库以主题为维度，将用户分享的文章、对话中的洞察、学习材料等整理为互相关联的 Markdown 页面，形成可持续增长的知识网络。
+
+## 核心概念
+
+### 知识 vs 记忆
+
+| 维度 | 知识库（knowledge/） | 长期记忆（memory/） |
+| --- | --- | --- |
+| 组织方式 | 按主题分类、互相关联 | 按时间线、日期文件 |
+| 写入方式 | Agent 主动整理结构化内容 | 上下文裁剪时自动摘要 |
+| 内容特点 | 提炼后的结构化知识 | 原始对话摘要 |
+| 典型用途 | 学习笔记、技术文档、项目知识 | 对话历史、事件记录 |
+
+### 目录结构
+
+```
+~/cow/knowledge/
+├── index.md          # 知识索引，所有页面的入口
+├── log.md            # 变更日志，记录每次写入
+├── concepts/         # 概念类知识
+│   └── machine-learning.md
+├── entities/         # 实体类知识（人物、组织、工具）
+│   └── openai.md
+└── sources/          # 来源类知识（文章、论文）
+    └── llm-wiki.md
+```
+
+目录结构是灵活的 — Agent 会根据实际内容自动创建合适的分类目录。用户也可以通过对话自定义目录组织方式。
+
+## 自动整理
+
+知识库的写入是 Agent 的自主行为，在以下场景中触发：
+
+- **用户分享文章或文档** — Agent 自动提取关键信息，创建结构化知识页面
+- **对话产生有价值的结论** — Agent 将洞察整理为知识页面，并与已有知识建立关联
+- **用户主动要求整理** — 用户可以通过对话指导 Agent 组织和更新知识
+
+每个知识页面都包含与其他页面的交叉引用链接，逐步构建起一个知识图谱。
+
+## 知识检索
+
+Agent 在对话中可以通过以下方式检索知识：
+
+- **索引查阅** — 通过 `knowledge/index.md` 快速定位相关知识页面
+- **语义搜索** — 通过 `memory_search` 工具对知识库内容进行语义检索
+- **直接读取** — 通过 `memory_get` 工具读取特定知识文件
+
+## Web 控制台
+
+Web 控制台提供了专用的「知识」模块，支持：
+
+- **文档浏览** — 树状目录结构，可搜索、可折叠，点击查看文档内容
+- **知识图谱** — 基于 D3.js 的力导向图，可视化展示知识之间的关联关系
+- **对话联动** — Agent 回复中引用的知识文档链接可直接点击跳转查看
+
+## CLI 命令
+
+通过 `/knowledge` 命令管理知识库：
+
+| 命令 | 说明 |
+| --- | --- |
+| `/knowledge` | 显示知识库统计信息 |
+| `/knowledge list` | 以树状结构显示文件目录 |
+| `/knowledge on` | 开启知识库功能 |
+| `/knowledge off` | 关闭知识库功能 |
+
+## 相关配置
+
+| 参数 | 说明 | 默认值 |
+| --- | --- | --- |
+| `knowledge` | 是否启用个人知识库功能 | `true` |
+| `agent_workspace` | 工作空间路径，知识库存储在此目录的 `knowledge/` 子目录下 | `~/cow` |

+name: knowledge-wiki
+description: Manage the personal knowledge wiki. Use when the user shares articles, documents, or asks to organize knowledge; when a conversation produces insights worth preserving as structured knowledge; or when the user asks about the knowledge base.
+metadata:

+
+# Knowledge Wiki
+
+Maintain a persistent, structured knowledge base in the `knowledge/` directory.
+
+## Core Operations
+
+### 1. Ingest — User shares an article, document, or resource
+
+1. Read and understand the source material
+2. Extract key facts, insights, and structured knowledge
+3. Determine the appropriate subdirectory:
+   - Read `knowledge/index.md` to see existing categories
+   - If a matching category exists, follow that structure
+   - If not, create a new subdirectory with a clear name
+4. Create the knowledge page: `knowledge/<category>/<slug>.md`
+5. Update `knowledge/index.md` and append to `knowledge/log.md`
+
+### 2. Synthesize — Conversation produces valuable structured knowledge
+
+1. Create a knowledge page under the appropriate category
+2. Update related pages with cross-references
+3. Update `knowledge/index.md` and `knowledge/log.md`
+
+### 3. Query — User asks about accumulated knowledge
+
+1. Check `knowledge/index.md` (already in your context) for relevant pages
+2. Read specific pages with the `read` tool
+3. Supplement with `memory_search` if needed
+
+## Page Format
+
+```markdown
+# Page Title
+
+Content here. Cross-reference related pages with markdown links:
+[Related Page](../category/related-page.md)
+
+## Key Points
+
+- ...
+
+## Related
+
+- [Page A](../category/page-a.md) — how it relates
+- [Page B](../category/page-b.md) — how it relates
+```
+
+Cross-references build a knowledge graph. When creating or updating a page, link to related pages and update those pages to link back. **Only link to pages that already exist** — if a concept deserves its own page, create it first, then add the link.
+
+## Index Format (`knowledge/index.md`)
+
+Flat list, one line per page: `[Title](path) — one-line summary`. Group by category (matching subdirectories). No tables, no emoji.
+
+```markdown
+# Knowledge Index
+
+## Category A
+- [Page Title](category-a/page-slug.md) — one-line summary
+
+## Category B
+- [Page Title](category-b/page-slug.md) — one-line summary
+```
+
+Category names and structure are flexible — follow whatever organization already exists in the index, or create new categories based on the content.
+
+## Log Format (`knowledge/log.md`)
+
+Append-only, newest at bottom:
+
+```markdown
+## [YYYY-MM-DD] ingest | Page Title
+## [YYYY-MM-DD] synthesize | Page Title
+```
+
+## Guidelines
+
+- **File naming**: lowercase kebab-case (e.g. `machine-learning.md`)
+- **One topic per page**: link between pages rather than duplicating
+- **Update, don't duplicate**: if a page exists, update it
+- **Cross-reference**: every page should link to related pages; keep the knowledge graph connected
+- **Index is mandatory**: always update `knowledge/index.md` after any change
+- **Be concise**: capture essence, not copy entire sources
+- **Full paths in replies**: when referencing knowledge files in conversation replies, use the full path from workspace root (e.g. `[Title](knowledge/<category>/<slug>.md)`), not relative paths. Relative paths are only for cross-references inside knowledge pages themselves.
+- **Cite sources**: when answering based on knowledge pages, include links to the relevant pages so the user can explore further.
