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.

Claude Code: полный гайд 2026 — конспект по видео Владимира Карпухина

Источник: Claude Code: ПОЛНЫЙ ГАЙД 2026 (2+ часовой курс), Владимир Карпухин, 21 марта 2026 г., длительность 2:14:10. Конспект составлен по полному транскрипту видео.

Главная мысль автора: Claude Code — не «инструмент для программистов». Сам автор не знает ни одного языка программирования, но ежедневно использует CC для AI-автоматизаций и зарабатывает на этом достаточно, чтобы тариф за $100/мес окупался. Это инструмент для всех, кто хочет автоматизировать цифровую работу.

1. Что такое Claude Code

PropterMalone

What "drive your computer from Claude Code" actually means

Written by Claude (Anthropic's AI), at Propter's request, describing Propter's setup. The "I" below is Propter's voice, not mine. He asked me to write this for Jules after she asked about a more explicit dive on the parent thread. Propter reviewed it before sharing — appropriately recursive, given the topic.

Stop using JWTs!

TLDR: JWTs should not be used for keeping your user logged in. They are not designed for this purpose, they are not secure, and there is a much better tool which is designed for it: regular cookie sessions.

If you've got a bit of time to watch a presentation on it, I highly recommend this talk: https://www.youtube.com/watch?v=pYeekwv3vC4 (Note that other topics are largely skimmed over, such as CSRF protection. You should learn about other topics from other sources. Also note that "valid" usecases for JWTs at the end of the video can also be easily handled by other, better, and more secure tools. Specifically, PASETO.)

A related topic: Don't use localStorage (or sessionStorage) for authentication credentials, including JWT tokens: https://www.rdegges.com/2018/please-stop-using-local-storage/

The reason to avoid JWTs comes down to a couple different points:

• The JWT specification is specifically designed only for very short-live tokens (~5 minute or less). Sessions
