The skill
Helps build clear, good-looking app screens.
Only when you ask.
Better design
Every screen change follows your design rules. Your app looks better each time.

When does it start? How does it check its work? What does it remember?
One pull request per run, at most two rework rounds on failed checks.
The agent reads .interface-design/system.md and the existing tokens and components.
Without a system file it lists domain, color world, signature and defaults, then asks if the direction feels right.
Before each component it writes intent, hierarchy, palette, depth, surfaces, typography and spacing.
It prefers native HTML, then a headless primitive, then the project's own components and tokens.
It runs build, typecheck and tests, then checks the screen at desktop and mobile widths.
Swap, squint, signature and token tests must pass before showing the result.
It offers to save new reusable patterns to system.md, and writes them when you say yes.
It writes only in its own folder and asks you before anything goes out.
Read both lists. If the left one sounds like you, the Interface Design skill helps.
No. It targets dashboards, admin panels, SaaS apps, settings and data screens. Marketing pages need another skill.
Each save adds decisions to system.md, and later runs hold new code to those values.
Copy the prompt at the top into your agent. It installs the skill from Dammyjay93/interface-design and sets up the habit. Or run npx skills add Dammyjay93/interface-design --skill interface-design.
Yes. It is published under MIT. Habit is free too.
