Proof · blind tests

Made with the skill.

A fresh Claude session got the Propel skill pack and a one-line prompt. Nothing else: no screenshots, no hand-picked components, no retouching afterwards. The screens below are exactly what came back, with the share of real kit instances counted layer by layer.

How we count

Kit share, and the test we left out.

Kit share = layers that are instances of Propel components ÷ all top-level layers in the output. Drawn layers are anything Claude made by hand instead of placing a component.

Of five blind tests, four are shown. The fifth, a three-step CRM onboarding flow, came in at about 35% kit share. Multi-screen flows are the next thing we are improving in the skill, and we will publish that test again when it passes.
