# Hallmark — AI Coding Tool Review & Pricing

> Hallmark is a design skill for Claude Code, Codex, Cursor and OpenCode that aims to stop AI-built web pages from looking machine-made. It picks themes from a catalog of 48, builds each page around what the visitor came to do, and lints the result in a real browser against common AI-design tells before a fresh-context reviewer has the final say.
