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.

Towards a safer SwiftUI environment

Swift UI's @EnvironmentObject is currently prone to runtime errors. If a view uses an environment object of a type that was not injected using environmentObject a fatalError occurs. This document sketches a design that would support compile-time checking of environment object usage. It requires a few language enhancements.

Tuple intersection types

Swift's protocol composition types such as Protocol1 & Protocol2 are a form of intersection types. Other forms of intersection types are possible. For example, Flow has object intersection types. Tuple intersection types for Swift would be very similar to these.

Below, you can see the examples in the Flow documentation converted to Swift's tuples:

	import Foundation

	extension String {
	//Know if self is only composed by numbers
	var isNumber: Bool {
	return !self.isEmpty && CharacterSet.decimalDigits.isSuperset(of: CharacterSet(charactersIn: self))
	}

	}
	//Struct to check Regular Expresions

	//
	// NotificationService.swift
	// Service

	typealias DataSource = UITableViewDiffableDataSource<Int, String>
	typealias SnapShot = NSDiffableDataSourceSnapshot<Int, String>


	private var dataSource: DataSource!

	@IBOutlet weak var tableView: UITableView!

	override func viewDidLoad() {
	super.viewDidLoad()

	#!/bin/bash

	OUR_DIR=$(cd $(dirname "$0"); pwd)
	[[ ! -d "$PREF_DIR" ]] && mkdir -p "$PREF_DIR" 2>/dev/null

	function echo_start_items() {
	echo '<?xml version="1.0"?>'
	echo '<items>'
	}
