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.

Promises reading list

This is a list of examples and articles, in roughly the order you should follow them, to show and explain how promises work and why you should use them. I'll probably add more things to this list over time.

This list primarily focuses on Bluebird, but the basic functionality should also work in ES6 Promises, and some examples are included on how to replicate Bluebird functionality with ES6 promises. You should still use Bluebird where possible, though - they are faster, less error-prone, and have more utilities.

I'm available for tutoring and code review :)

You may reuse all gists for any purpose under the WTFPL / CC0 (whichever you prefer).

React now supports the use of ES6 classes as an alternative to React.createClass().

React's concept of Mixins, however, doesn't have a corollary when using ES6 classes. This left the community without an established pattern for code that both handles cross-cutting concerns and requires access to Component Life Cycle Methods.

In this gist, @sebmarkbage proposed an alternative pattern to React mixins: decorate components with a wrapping "higher order" component that handles whatever lifecycle methods it needs to and then invokes the wrapped component in its render() method, passing through props.

While a viable solution, this has a few drawbacks:

There's no way for the child component to override functionality defined on the higher order component.
