clean-interface-design

clean-interface-design is a skill for Claude Code from HalidSaglam/saglitzdesign-mcp. It costs 95 tokens per session (1,470 once invoked), scanned A, original, MIT.

Guidance for designing calm, uncluttered interfaces with clear hierarchy, spacing, typography, colors, and controls. A user interface is the visible part of an app or website that people use.

In plain words
What is it for?
Use it when creating or restyling web, iOS, Android, or Mac interfaces that need a restrained and coherent visual system.
Why use it?
It helps avoid crowded layouts, inconsistent styling, and screens with too many competing actions or visual choices.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

clean-interface-design scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Clean Interface Design

Most "AI-looking" UI fails the same way: too many colors, too many type sizes, inconsistent radii, no clear primary action, and no breathing room. Fix those and almost anything looks intentional.

Full depth (specs, contrast math, tokens, real examples) is available via the SaglitzDesign MCP (npx saglitzdesign-mcp) — docs clean-app-design, color-systems, typography, spacing-layout, visual-craft-standards; tools create_design_system (one call → the whole foundation), generate_layout_system, generate_design_tokens, audit_accessibility, and audit_design_system to measure whether the restraint below actually held.

The rules that do most of the work

  1. One accent color + its soft tints. Pick a single brand/accent hue. Use it for the primary action and key highlights only (~10% of the surface). Everything else is a neutral ramp. Scarcity is what makes the accent pop.
  2. Whitespace is a feature. Give elements room to breathe; when unsure, add more space, not more UI. Grouping is communicated by space — gap within a group must be smaller than gap between groups.
  3. One corner radius system. Pick a radius and apply it consistently to cards, inputs, buttons, and icon containers. Don't mix 4px cards with 16px buttons. Pill buttons pair with pill inputs.
  4. Two or three type sizes, not five. A tight scale (e.g. 14 / 16 / 24) with weight and color for hierarchy reads far cleaner than five sizes. Express hierarchy with size + weight + color (3 opacity levels), not more fonts.
  5. One clean font. A single quality family is enough. Good geometric/neutral options: system fonts (SF/Segoe/Roboto), Inter, Geist, Open Runde (free, rounded-geometric). Two families max — a distinctive display + a workhorse body.
  6. One icon family, one weight. Use a single cohesive set at a single stroke/weight. Good free sets: Solar (incl. duotone), Lucide, Phosphor, Heroicons. Never mix icon families.
  7. Borders OR shadows — pick one. Choose one system to separate surfaces (borders read better in dark mode; soft shadows on light). Don't stack a border and a shadow and a fill on the same card.
  8. One primary action per view. Exactly one filled/high-emphasis button per screen or section. Everything else is secondary (tonal/outline) or tertiary (text). Two filled buttons side by side destroy hierarchy.
