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.

How to install Homebrew package manager on Steam Deck

(See also installing Distroboxm, which is included in SteamOS 3.5 and newer: https://distrobox.it/ )
(See also installing Nix package manager: https://determinate.systems/posts/nix-on-the-steam-deck )

You can install Homebrew (a package manager for macOS and Linux) without disabling the read-only partition with sudo steamos-readonly disable.
The package manager can be used alongside Flatpaks. Some software is only available on Flathub, and some software is only available on Homebrew.

1. Switch to desktop mode (hold power button until a menu appears, then select "Switch to desktop mode")
2. Click the logo at the bottom left, go to System, then go to Konsole

Audit this entire codebase for materially useful simplifications in its data structures, state representation, control flow, algorithms, and ownership.

This is an audit-only exercise. Do not edit files, run tests, implement recommendations, commit, or push. Read-only inspection commands are allowed.

You are the coordinator. Continue until the complete codebase has been reviewed and the final audit is validated.

1. Establish the coverage contract

Inspect the repository and inventory every identifiable subsystem.

GeoServer jsonArrayContains SQLi -> PostgreSQL RCE / SQL / exfiltration PoC

GeoTools FilterToSqlHelper.constructEquality writes the `expected` argument of
jsonArrayContains RAW into the SQL string (only the JSON pointer is escaped):

    jsonb_path_exists("data"::jsonb, '$ ? (@.a == "<VALUE>")')

A single quote in VALUE breaks out of the string literal, closes the call
