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.

Enabling the Group Policy Editor on Windows 10 Home

On Windows 10 Home edition, there is no Local Group Policy Editor (gpedit.msc) and no Local Security Policy Editor (secpol.msc). These tools are reserved to Professional editions of Windows.

It is however possible to install them on Windows 10 Home if you need them.

Open a PowerShell window as administrator and run the following command:

secretsquirrel

cat /tmp/test.sh
:; if [ -z 0 ]; then
  @echo off
  goto :WINDOWS
fi

if [ -z "$2" ]; then
  echo "usage: $0 <firstArg> <secondArg>"
  exit 1
fi

# This script will remove automatic association for all networks not listed in the whitelist
# passed as the first argument. Passwords will NOT be removed from the Keychain.
#
# Alternatively, you can untick "Remember networks" in Network Preferences > Wi-Fi > Advanced,
# but then you won't be able to auto-join networks even temporarily, and you might already
# have a long list to go through.

DLL Execution via Excel.Application RegisterXLL() method

A DLL can be loaded and executed via Excel by initializing the Excel.Application COM object and passing a DLL to the RegisterXLL method. The DLL path does not need to be local, it can also be a UNC path that points to a remote WebDAV server.

When delivering via WebDAV, it should be noted that the DLL is still written to disk but the dropped file is not the one loaded in to the process. This is the case for any file downloaded via WebDAV, and they are stored at: C:\Windows\ServiceProfiles\LocalService\AppData\Local\Temp\TfsStore\Tfs_DAV\.

The RegisterXLL function expects an XLL add-in which is essentially a specially crafted DLL with specific exports. More info on XLL's can be found on MSDN

The XLL can also be executed by double-clicking the .xll file, however there is a security warning. @rxwx has more notes on this here inc
