An open-source command-line tool that makes App Store screenshots from the running app. It captures the app in the iOS Simulator, lays the screens out as slides in HTML and CSS, renders them at the exact sizes Apple asks for, checks them on the rendered pixels (sizes, alpha, text size, cut-offs, contrast) and uploads them through the App Store Connect API. Every command prints JSON, so an agent can drive it. The EcoSort screenshots above and on the App Store were made with it.

App Store screenshots made from the running app
Two tools that came out of shipping apps alone, from a Linux PC, with coding agents doing a lot of the typing.
