Turns working solutions into reusable templates so you're not reinventing the wheel every time you solve something twice. It walks you through identifying what actually worked in a workflow, generalizing it into a pattern with clear "when to use" and "when NOT to use" sections, then testing if it actually applies elsewhere. The format is sensible: problem, template, variants, pitfalls, examples. Honestly most useful after you've iterated on something enough times that you're tired of explaining it, or when you catch yourself copy-pasting the same approach across projects. Pairs with calibrate to keep your pattern library consistent.
