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.

Intro

The below is a breakdown / bird's eye view of how a sparse-array backed ECS like EnTT or Shipyard works.

Please see the thanks and references at the bottom - without their help I would not have been able to share this breakdown with you... everything here is really just notes and rephrasing of what they've written already :)

Also, these notes do not cover archetype systems (like unity) nor adaptations of archetypes (like in Flecs). Though there's a couple comparative footnotes at the end.

Here we go!
