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.

CSS Responsive Rules

目的

レスポンシブ実装の判断基準を明確にし、不要なブレイクポイントとコード量を最小化する。 CSS はブラウザへの「提案」であり、厳密な命令ではない。ブラウザに委ねられる仕事は委ねる。

基本方針: エスカレーション順序

レスポンシブ対応は以下の優先順序で検討する。上位で解決できるなら下位は使わない。
