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.

Using in Rails engines

If the application UI consists of multiple frontend application, you'd probably like to isolate their building too (e.g. if you use different frameworks/versions). Hence we needed our webpack(-er) to be isolated too: separate package.json, dev server, compilation process.

You can do this by adding another Webpacker instance to your application.

This guide describes how to do that using Rails engines.

Step 1: create Rails engine.

How to setup Cypress on Rails apps

You need to update circle.yml:

machine:
  node: # add node dependency
    version:
      7.4

environment:

dux

class DecoratorClone
  def initialize(model)
    @model = model
  end

  def method_missing(m, *args)
    raise NameError, "Decorator method '#{m}' not found" unless @model.respond_to?(m)
    @model.send(m, *args)
  end
end

CRUD with Ember (+ Data)

Ember's official documentation describes a number of low-level APIs, but doesn't talk much about how to put them together. As a result, a simple task such as creating a simple CRUD application is not obvious to a newcomer.

<comment-box>
  <h1>{ opts.title }</h1>

  <comment-list url={ opts.url } comments={ comments } />
  <comment-form url={ opts.url } />

  this.comments = []

  add(comment) {
    this.comments.push(comment)

What this does

This is the initial code. Improvements are likely to be had.

• This creates an activity feed that can track updates, destroys, creates in a MySQL database.
• This is inspired by part of the "public_activity" gem.
• For Updates, what changed will be automatically stored as a hash.
• Bootstrap's usage is assumed, as is Devise's "current_user". ActiveRecord must be used as well. These can easily be changed however.

How to use it

module CapybaraWithPhantomJs

  # Create a new PhantomJS session in Capybara
  def new_session

    # Register PhantomJS (aka poltergeist) as the driver to use
    Capybara.register_driver :poltergeist do |app|
      Capybara::Poltergeist::Driver.new(app)
