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.

smart-commit

AI-powered git commits using Claude Code CLI

A zsh function that analyzes your staged and unstaged changes, then creates logical, atomic commits following the Conventional Commits specification.

What It Does

When you run smart-commit, Claude will:

Grouping results and removing unwanted ones

Here we want to scrape product name, price and rating from ebay product pages:

url = 'https://www.ebay.com/itm/Sony-PlayStation-4-PS4-Pro-1TB-4K-Console-Black/203084236670' 

wanted_list = ['Sony PlayStation 4 PS4 Pro 1TB 4K Console - Black', 'US $349.99', '4.8'] 

scraper.build(url, wanted_list)

local ssl certificates that work

motivation

in web dev sometimes you are constrained to develop from behind a https:// local server. i spent two days making this work and i want to write it down here, so that next time apple upgrades OS X and i decide to do a clean install (forgetting to backup certain things) i dont waste this amount of time anymore (i hope).

maybe it helps someone else too. that would make me very happy too.

forget openssl

major pita to remember commands. i don't think there is anything better that makes your mom feel like you are a hacker, than showing her how to type:
