anti-AI-slop UI design skills for coding agents
Hallmark is an agent skill for Claude Code, Cursor, and Codex that uses themes, slop-test gates, and self-critique to generate UI that avoids AI-generated slop.
Same problem, same approach. Swapping one for another is a config change, not a rewrite.

These projects were analysed and named hallmark among their alternatives. The relationship is not symmetric — how hallmark rates them is a separate judgement, made when hallmark is analysed in its own right.
