Hallmark: Together AI Open-Sources an "Anti-AI-Slop" Tool for Web Design

Short summary

Together AI open-sources Hallmark, a design skill layer for AI coding assistants that combats 'AI slop' — the generic, repetitive designs produced by tools like Cursor and Claude Code. Hallmark runs 57 design quality checks, offers 20 visual themes and 21 macrostructures, and rejects lazy defaults before code is output. It integrates via a single npx command and supports build, audit, redesign, and study commands.
