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.

PI is a TypeScript toolkit for building AI agents. It's a monorepo of packages that layer on top of each other: pi-ai handles LLM communication across providers, pi-agent-core adds the agent loop with tool calling, pi-coding-agent gives you a full coding agent with built-in tools, session persistence, and extensibility, and pi-tui provides a terminal UI for building CLI interfaces.

These are the same packages that power OpenClaw. This guide walks through each layer, progressively building up to a fully featured coding assistant with a terminal UI, session persistence, and custom tools.

By understanding how to compose these layers, you can build production-grade agentic software on your own terms, without being locked into a specific abstraction.

Pi was created by @badlogicgames. This is a great writeup from him that explains some of the design decisions made when creating it.

Run Visual Studio Code for Linux from WSL

Thanks a lot to mredbishop and others for their insturctions posted here. This is just a recap of what they figured out.

This process was tested on WSL Ubuntu 18.04.

Install VcXsrv on Windows

1. Dowload the VcXsrv installer from https://sourceforge.net/projects/vcxsrv/
2. Install the software on Windows

Add VS Code repositories

Deprecated in favor of Valet Wiki Page

I set up the wiki page for the valet-wsl project and moved the install guide there. This way it can have user contributions. Please have all disscussions or issues under the valet-wsl project so I can be aware of it. Please go to Valet Wsl Installation Guide

.profile, .bash_profile, .bashrc. The Long Story.

Traditionally, when you log into a Unix system, the system would start one program for you. That program is a shell, i.e., a program designed to start other programs. It's a command line shell: you start another program by typing its name. The default shell, a Bourne shell, reads commands from ~/.profile when it is invoked as the login shell.

Bash is a Bourne-like shell. It reads commands from ~/.bash_profile when it is invoked as the login shell, and if that file doesn't exist¹, it tries reading ~/.profile instead.
