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.

Migrate git repos script

I used this for migrating git repos from Bitbucket to Github. It uses git's --mirror flag for cloning and pushing to also transfer all tags and branches.

It would be helpful to have SSH keys set up on both ends. Then all you should have to do is to make sure the hardcoded orgname is set to the appropriate one for both the source and destination.

Once I migrated repos, I used this to replace my origin url locally (assumes using ssh):

sed -i s/bitbucket.org:orgname/github.com:orgname/g .git/config
