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.

3DS Romhack Installation Guide

Many romhacks still provide old instructions for previous hacking methods. This guide is up to date and provides instructions that should work with most romhacks.

What you need

• A custom firmware 3DS with the latest version of Luma3DS (if you do not have this, follow the guide)
• A romhack to install

Native Secure Enclave backed ssh keys on MacOS

It turns out that MacOS Tahoe can generate and use secure-enclave backed SSH keys! This replaces projects like https://github.com/maxgoedjen/secretive

There is a shared library /usr/lib/ssh-keychain.dylib that traditionally has been used to add smartcard support to ssh by implementing PKCS11Provider interface. However since recently it also implements SecurityKeyProivder which supports loading keys directly from the secure enclave! SecurityKeyProvider is what is normally used to talk to FIDO2 devices (e.g. libfido2 can be used to talk to your Yubikey). However you can now use it to talk to your Secure Enclave instead!

API Pricing & Free-Tier Cheat Sheet

Quick reference for picking a provider/CLI on day 1. All numbers verified early-mid 2026 — confirm live before you depend on them. Pricing and quotas change frequently (especially Chinese providers and free-tier limits).

TL;DR — what to use day 1

Goal	Pick	Why
Zero cost, zero card	Gemini CLI with personal Google account	Generous free tier, no card required, 60 req/min
Zero cost + multi-provider	opencode + Gemini API key (AI Studio free tier)	Model-agnostic CLI; swap providers later without changing tool
