Hallmark
Check out Nutlope/hallmark, an anti-AI-slop design skill for Claude Code, Cursor, and Codex. It builds clean, human-feeling web pages using 50 custom themes, real photographs, and strict linter gates to eliminate generic AI design patterns.
Detailed Overview & Review
Verified AnalysisHallmark (created by Together AI) is a specialized design skill built for AI coding assistants like Claude Code, Cursor, Codex, and OpenCode. Its primary mission is to prevent "AI slop"—the repetitive, machine-generated look that plagues modern AI-assisted web development (such as forced eyebrows over headings, generic colored title words, and empty placeholder frames).
Instead of relying on cookie-cutter templates, Hallmark enforces a hard quality floor and applies a strict multi-tier review system. It selects from a catalog of 50 material-based themes (ranging from Dusk and Cobalt to Atelier and Vantage), designs pages around the actual job they need to do (like booking or selling), and uses a built-in linter (sloplint) to test layouts across different screen widths.
Key features include:
Real Photographs: Utilizes over 755 openly licensed Wikimedia Commons photos with proper attribution, avoiding generic stock photography sites.
Redesign & Audit Tools: You can easily audit or fully overhaul existing codebases using commands like /hallmark redesign or /hallmark audit.
Zero Inventory of Invented Facts: It pulls from real content, screenshots, or local dev environments rather than making up placeholder data.
Licensed under the MIT license, it can be installed instantly via npm (npx skills add nutlope/hallmark -g) to give your coding assistant a refined, human-crafted design eye.
