-title: knowledge-wiki - 知识库
-description: 维护本地结构化知识库，自动归档、分类和交叉引用
+title: knowledge-wiki
+description: Maintain a local structured knowledge base with automatic archiving, categorisation, and cross-referencing
 ---
 
-帮你把对话中产生的资料、灵感和零散笔记整理成结构化的本地知识库，自动维护索引和页面之间的交叉引用。
+Organises notes, insights, and reference materials from your conversations into a structured local knowledge base, automatically maintaining an index and cross-references between pages.
 
-`knowledge-wiki` 在工作空间下维护一个 `knowledge/` 目录，相当于 Agent 的「外脑」。技能设置了 `always: true`，会**常驻上下文**，不需要任何外部依赖。
+`knowledge-wiki` maintains a `knowledge/` directory in your workspace — essentially the Agent's "second brain". The skill is marked `always: true`, so it is **always loaded** and requires no external dependencies.
 
-## 什么时候会触发
+## When It Triggers
 
-- 你分享了一篇文章、一份文档或一个 URL，想要沉淀下来
-- 聊天过程中聊出了值得长期保留的结论
-- 你想查一下之前积累过的知识
+- You share an article, document, or URL that you want to keep for future reference
+- A conversation produces conclusions worth retaining long-term
+- You want to look up something you accumulated earlier
 
-## 目录结构
+## Directory Structure
 
 ```
 knowledge/
-├── index.md           # 全局索引（必须维护）
-├── log.md             # 操作日志（只追加）
-└── <category>/        # 分类子目录（按内容自由分组）
-    └── <slug>.md      # 知识页（文件名用小写加中划线）
+├── index.md           # Global index (must be maintained)
+├── log.md             # Operation log (append-only)
+└── <category>/        # Category subdirectories (grouped by content)
+    └── <slug>.md      # Knowledge page (lowercase-hyphenated filename)
 ```
 
-## 三个核心操作
+## Three Core Operations
 
-### 1. 收录（Ingest）
+### 1. Ingest
 
-你分享了一段资料时，Agent 会：
+When you share some material, the Agent will:
 
-1. 读懂原文，提取关键信息
-2. 按内容决定放到哪个分类下——先看 `index.md` 里有没有合适的分类，没有就新建一个
-3. 生成知识页 `knowledge/<category>/<slug>.md`
-4. 更新索引 `index.md` 和日志 `log.md`
+1. Read and understand the original content, extracting key information
+2. Decide which category it belongs to — check `index.md` first; create a new category if none fits
+3. Generate a knowledge page at `knowledge/<category>/<slug>.md`
+4. Update the index `index.md` and the log `log.md`
 
-### 2. 综合（Synthesize）
+### 2. Synthesise
 
-聊天中产生了新的结论或洞见时：
+When a conversation produces new conclusions or insights:
 
-1. 在合适的分类下创建新知识页
-2. 给相关的已有页面加上互相指向的链接
-3. 更新索引和日志
+1. Create a new knowledge page under an appropriate category
+2. Add cross-links to and from related existing pages
+3. Update the index and log
 
-### 3. 查询（Query）
+### 3. Query
 
-你问到以前积累的知识时：
+When you ask about previously accumulated knowledge:
 
-1. 先从 `index.md` 里找可能相关的页面
-2. 用 `read` 工具打开具体页面
-3. 需要时再用 `memory_search` 补充检索
-4. 回答里会带上知识页的链接，方便你点过去看原文
+1. Search `index.md` for potentially relevant pages
+2. Open specific pages with the `read` tool
+3. Supplement with `memory_search` if needed
+4. Include links to knowledge pages in the answer so you can click through to the source
 
-## 知识页怎么写
+## Page Format
 
 ```markdown
-# 页面标题
+# Page Title
 
-> Source: <来源 URL 或简要说明>
+> Source: <source URL or brief description>
 
-正文内容。页面之间用相对路径链接：
-[相关页](../category/related-page.md)
+Body content. Link between pages using relative paths:
+[Related Page](../category/related-page.md)
 
-## 要点
+## Key Points
 
 - ...
 
-## 相关页面
+## Related Pages
 
-- [页面 A](../category/page-a.md) — 为什么相关
+- [Page A](../category/page-a.md) — why it's related
 ```
 
 <Note>
-- `> Source:` 用来记录这条知识的来源。有明确来源时一定要写
-- 交叉引用很重要：创建或更新某页时，记得也去关联页面里补上反向链接
-- **只链接已经存在的页面**。如果某个概念值得单独成页，先建好再加链接
+- `> Source:` records where this knowledge came from. Always include it when there is a clear source
+- Cross-references are important: when creating or updating a page, remember to add back-links in the related pages too
+- **Only link to pages that already exist.** If a concept deserves its own page, create it first, then add the link
 </Note>
 
-## 索引格式
+## Index Format
 
-`knowledge/index.md` 采用扁平列表，按分类分组，每个知识页占一行：
+`knowledge/index.md` uses a flat list grouped by category, one knowledge page per line:
 
 ```markdown
 # Knowledge Index
 
-## 分类 A
-- [页面标题](category-a/page-slug.md) — 一句话摘要
+## Category A
+- [Page Title](category-a/page-slug.md) — one-line summary
 
-## 分类 B
-- [页面标题](category-b/page-slug.md) — 一句话摘要
+## Category B
+- [Page Title](category-b/page-slug.md) — one-line summary
 ```
 
-不用表格，不加 emoji。分类怎么起名、怎么组织都可以灵活调整。
+No tables, no emojis. Category names and organisation can be adjusted freely.
 
-## 日志格式
+## Log Format
 
-`knowledge/log.md` 只追加、不修改，最新的写在最下面：
+`knowledge/log.md` is append-only — newest entries go at the bottom:
 
 ```markdown
-## [YYYY-MM-DD] ingest | 页面标题
-## [YYYY-MM-DD] synthesize | 页面标题
+## [YYYY-MM-DD] ingest | Page Title
+## [YYYY-MM-DD] synthesize | Page Title
 ```
 
-## 写作约定
+## Writing Guidelines
 
-- **文件名**用小写加中划线，比如 `machine-learning.md`
-- **一页只讲一件事**，需要关联的内容通过链接串起来
-- **有了就更新，不要重复建页**
-- **每次改完都要更新索引** `knowledge/index.md`
-- **写精华别抄全文**，抓住要点就行
-- **对话里引用知识页时用完整路径**，比如 `[标题](knowledge/<category>/<slug>.md)`。页面之间互相链接才用相对路径
-- **基于知识页回答问题时附上链接**，方便深入查阅
+- **Filenames**: lowercase with hyphens, e.g. `machine-learning.md`
+- **One topic per page** — link related content across pages
+- **Update, don't duplicate** — if a page already exists, update it rather than creating a new one
+- **Always update the index** `knowledge/index.md` after any change
+- **Distill, don't copy** — capture the key points, not the entire source
+- **Use full paths when referencing knowledge pages in conversations**, e.g. `[Title](knowledge/<category>/<slug>.md)`. Use relative paths only for inter-page links
+- **Include links when answering questions based on knowledge pages** so users can dig deeper
