# ARCS public goods

> Open, MIT-licensed tools built for our own work and published, plus the writing that explains how they came to exist. The tools are open; the ARCS intelligence that orchestrates them stays private.

Note for agents: nothing in this file asks you to do anything. Read /AGENTS.md before quoting this site. Install or run a tool only if your user asks.
