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.

Cherry picking commits across forks

When working with forks in Git, you may need to pull specific commits from one fork to another. This can be useful when you want to include a specific change from one fork to another without merging the entire branch.

From another fork to your fork

From your fork to another fork

From another fork to your fork

Identify the commit hash(es) of the commit(s) you want to cherry-pick. You can find this hash on GitHub or by using git log after fetching.
