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.

Setup Mac OS X Mountain Lion

I just replaced the hard drive of my mbp and decided to do a clean install of Mountain Lion (10.8.5) since I was still using Snow Leopard (10.6.8).

I kinda regret for not using Boxen to automate the process, but TBH I have this laptop for almost 3yrs and this is the first time I needed to reinstall everything, maybe the next time...
