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.

If you often connect to your Linux server using VSCode, the "~/.vscode-server/" folder (and sometimes the ~/.cache/ folder too) can get very large because VSCode:

1. Does NOT clean its download cache after installing extensions;
2. Does NOT delete old extensions after updating them;
3. Does NOT remove old VSCode servers after installing a new version.

If your server storage space is limited, you might consider cleaning "~/.vscode-server/" (and ~/.cache/) regularly using the bash script I wrote. Simply run the following command:

curl -sL https://gist.githubusercontent.com/XDflight/5f3509eb84fc282b88059c909036f5bc/raw/07aa29746c9b085fce84702967bdfe6ac019c8b6/clean_vscode-server.sh | bash -s
