Hallmark
A design skill for coding agents, released under MIT by Together AI, that goes after the most visible flaw of generated pages: they all look alike. Before rendering anything, it runs the page through fifty-seven anti-template tests, which hunt down the reflexes models picked up from seeing the same sites over and over, then through a self-critique. It picks a page structure and a theme suited to the brief from twenty-one catalogue themes, and switches to a custom mode when none fits. Four uses: build a page (the default), audit an existing page, redesign it, or study a reference site. Works in Claude Code, Cursor and Codex.
Strengths
- A mandatory self-critique before rendering, not just a list of bans
- An audit mode that works on an existing page without regenerating anything
- A custom mode for when no catalogue theme matches the brief
Limitations
- Overlaps Impeccable and Taste Skill: stacking all three produces contradictory instructions
- A thin brief falls back on a catalogue theme, which eventually becomes a recognisable template in its own right
Best for
- An agent that ships interchangeable pages despite a decent brief
- Screening a page already online for model reflexes before redesigning it
- Studying a reference site to draw a direction from it before building your own page
