The fourth release of hadley: every new site gets an AGENTS.md that tells your coding agent which documentation to read for what, hems and punch get a template for notes, and a site set to light or dark stays that way. How far an agent gets with hadley's documentation alone, I measured: five everyday tasks in under four minutes.
