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.

Humble Pi — local agentic coding on minimal hardware

A coding agent that runs entirely on your own machine. No API keys, no cloud, works offline.

pi is the agent you talk to. It runs against a local llama.cpp server hosting Google Gemma 4 (the unsloth builds).

Pick a model by how much memory you have:

Codex Desktop feature flag overrides

Runtime-only scripts for experimenting with hidden Codex Desktop UI feature flags. They launch Codex with a local Chrome DevTools Protocol port and inject renderer feature overrides. They do not modify Codex.app.

Run

First quit Codex Desktop. Only one desktop instance can run at a time, and the launcher needs to reopen it with the override hook.

Option A: ask the codex CLI to run it for you. Paste this into Terminal:

	#!/usr/bin/env python3

	# Funny enough, this script does everything but actually get crates :D

	import json
	import requests
	import tarfile
	import re
	from sys import exit, stderr
	from hashlib import md5, sha256

	@echo off
	REM // This batch will help frustrated AMD Ryzen user for being unable to normally use adb fastboot from Windows OS
	REM // I found this script on forum, I don't know who is the original creator of this registry hack, thank you very much
	REM // Credit belongs to the original creator
	REM // Just simply Run as Administrator

	reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\usbflags\18D1D00D0100" /v "osvc" /t REG_BINARY /d "0000" /f
	reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\usbflags\18D1D00D0100" /v "SkipContainerIdQuery" /t REG_BINARY /d "01000000" /f
	reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\usbflags\18D1D00D0100" /v "SkipBOSDescriptorQuery" /t REG_BINARY /d "01000000" /f
