Hallmark
A design skill with 21 themes and 57 slop checks, so no two pages look like one template.

View source What is it?
Hallmark picks a page structure for your brief, dresses it in one of 21 themes, then runs 57 "slop test" gates on typography, colour, layout and motion before handing the page back. Two pages for two different briefs feel like different sites, not colour swaps of one template.
It has four verbs: build new UI by default, audit existing code for anti-patterns, redesign a page while keeping its copy and brand, and study a screenshot or URL to extract the DNA of a design you admire. When no theme fits, a Custom mode designs from scratch.
Made by Together AI and works in Claude Code, Cursor and Codex.
