LLM Wiki

A pattern for building personal knowledge bases using LLMs.

This is an idea file, it is designed to be copy pasted to your own LLM Agent (e.g. OpenAI Codex, Claude Code, OpenCode / Pi, or etc.). Its goal is to communicate the high level idea, but your agent will build out the specifics in collaboration with you.

The core idea

Most people's experience with LLMs and documents looks like RAG: you upload a collection of files, the LLM retrieves relevant chunks at query time, and generates an answer. This works, but the LLM is rediscovering knowledge from scratch on every question. There's no accumulation. Ask a subtle question that requires synthesizing five documents, and the LLM has to find and piece together the relevant fragments every time. Nothing is built up. NotebookLM, ChatGPT file uploads, and most RAG systems work this way.

表格受密码保护时，我们修改数据Excel弹出“您试图更改的单元格或图表受保护，因而是只读的。
若要修改受保护单元格或图表，请先使用‘撤消工作表保护’命令(在‘审阅’选项卡的‘更改’组中)来取消保护。
可能会提示输入密码。这时候我们可以用VBA宏代码破解法来破解表格保护密码：
  第一步：打开该文件，先解除默认的“宏禁用”状态，方法是点击工具栏下的“选项”状态按钮，
         打开“Microsoft Office安全选项”窗口，选择其中的“启用此内容”，“确定”
         再切换到“视图”选项卡，点击“宏”→“录制宏”，出现“录制新宏”窗口，在“宏名”定义一个名称为：  
         PasswordBreaker，点击“确定”退出；
  第二步：再点击“宏”→“查看宏”，选择“宏名”下的“PasswordBreaker”并点击“编辑”，
         打开“Microsoft Visual Basic”编辑器，用如下内容替换右侧窗口中的所有代码：
