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.

Pure ESM package

The package that linked you here is now pure ESM. It cannot be require()'d from CommonJS.

This means you have the following choices:

Use ESM yourself. (preferred)
Use import foo from 'foo' instead of const foo = require('foo') to import the package. You also need to put "type": "module" in your package.json and more. Follow the below guide.
If the package is used in an async context, you could use await import(…) from CommonJS instead of require(…).
Stay on the existing version of the package until you can move to ESM.

ANSI Escape Sequences

Standard escape codes are prefixed with Escape:

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

What Will I Learn?

In general, you will learn some markdown tricks combined with standard HTML tags. In more details what you will learn:

Hide-show content
Writing codeblocks inside codeblocks
Combining and using italic, bold, superscript, subscript, and/or strikethrough
Quoting long sentence (using nested blockquotes)

Use Python to:

send a plain text email
send an email with attachment
receive and filter emails according to some criteria

	#!/usr/bin/env bash
	set -euo pipefail

	# patch-claude-code.sh — Rebalance Claude Code prompts to fix corner-cutting behavior
	#
	# What this does:
	# Patches the npm-installed @anthropic-ai/claude-code cli.js to rebalance
	# system prompt instructions that cause the model to cut corners, simplify
	# excessively, and defer complicated work.
