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.

curl security review log

Started: 2026-05-06
Commit: 455bebc2c7 (master)
Scope: 178k LoC C, lib/ + src/
Code links: https://github.com/curl/curl/tree/455bebc2c76223a1be26042f6d2393715c0df0cd (all line refs below pin to this commit)

Approach

curl is one of the most fuzzed and audited C codebases in existence (OSS-Fuzz, Coverity, CodeQL, multiple paid audits). Finding anything in the hot paths (HTTP/1, TLS, URL parsing core) is unlikely. Focus instead on:

m1nuz

#include <stdbool.h>
#include <stdio.h>
#include <stdlib.h>
#include <X11/Xlib.h>

bool quited = false;

void on_delete(Display * display, Window window)
{
    XDestroyWindow(display, window);
