This week’s tip of the week is Hallmark.
If you’ve been using AI to build frontends, you’ve probably noticed they can start to feel a little the same. Hallmark helps you stop shipping generic AI-generated UIs.
Hallmark is an AI skill that teaches your coding agent better design principles. Instead of settling for the same layouts and visual patterns over and over again, it encourages your AI to produce interfaces with better hierarchy, typography, spacing, and overall polish.
To put it to the test, I gave an AI the exact same prompt with and without Hallmark:
“Build a landing page for a developer tool called Logtail that helps developers search, filter, and analyze application logs. Include a hero section, a few key features, and a call to action to get started.”

Subjective and non-deterministic, but I prefer the Hallmark one.
Installing it takes less than a minute:

Once it’s installed, it works with Claude Code, Cursor, Codex, and other Skills-compatible coding agents. You don’t need to learn a new workflow. Just keep prompting like you normally would, but with Hallmark available to your agent.
A while back I shared Impeccable, another AI skill for building better user interfaces. Hallmark and Impeccable take slightly different approaches, but I’ve found they complement each other really well.
That’s it! Short and sweet. Until the next one!
