The Tool That Gave Us the Reins Had No Reins of Its Own — The Boundary Between Harness and Reins
"Reins Engineering — isn't that just harness engineering?" The two don't oppose each other — they're different parts of the same tack. But they are different parts. Even the world's best coding agent put no reins on its own code. That's because reins aren't something you have; they're something you apply.

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.'
