Why societies clash — and how we might fight less.
Production Traffic Is the Spec
Legacy code has no documentation. No tests either. And yet it's running right now. A month of well-recorded logs is the spec — build Hurl integration tests that capture the current behavior from production traffic, and you can pin down what the legacy does and lay a safety net for refactoring without reading a single line of code.

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.'
