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.

Install Termux, an Android terminal emulator that provides a Linux execution environment and various tools.
Update system packages in Termux:
```
$ pkg update -y
```

Registry edit that allows you to add Windows command-line, Powershell and/or GIT Bash to explorer context menu. source

on linux 4.19, I get

error creating new backup file '/var/lib/dpkg/status-old': Invalid cross-device link

when trying to install stuff on a ubuntu docker container. this seems to be an issue with metacopy https://www.spinics.net/lists/linux-unionfs/msg06109.html

issue can be worked around by running

ANSI Escape Sequences

Standard escape codes are prefixed with Escape:

Ctrl-Key: ^[
Octal: \033
Unicode: \u001b
Hexadecimal: \x1B
Decimal: 27
