Why societies clash — and how we might fight less.

Burning a City for a Single Answer
A trillion-parameter model burns a city's worth of electricity and water just to spit out a single answer. I thought this was insane. Searching for a way out, I learned something. The flaw everyone was trying to fix, the LLM's sycophancy, was the answer itself. Feed it fact and sycophancy becomes accuracy. This is the story of why I started Reins.

reins — Keep Only the Domain in a Quest CLI; Make the Ratchet a Framework
how-make-quest taught you to build a quest CLI with your bare hands. But build a second CLI and you write the same ratchet, the same scan/next/submit, the same tallying all over again. reins pulls that invariant out into a framework — reins supplies the ratchet, the command skeleton, the tallying, and export; you implement only your domain's gate (the four methods of gate.Definition). The gate is a catalog of cheese-defense rules, and the toulmin defeat graph hands the agent a strategy guide for 'why you lost and what to change to win.'
