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.

Finally! Here's the easy access to your iOS8 simulator apps you've been looking for :)
#!/bin/bash
#
# Using the information available in the new iOS8 simulator for each
# device/runtime (device.plist), this script creates a readable folder structure
# (no UDIDs, just simple device/runtime names). Inside that structure it creates
# soft links to your apps in development.
#
# You can run this script every time you install an app to your simulator, or
# you can simply call it to access this folder making sure it will always be
# updated :)
