name: claude-frontforge description: This skill is for interface design — dashboards, admin panels, apps, tools, and interactive products. NOT for marketing design (landing pages, marketing sites, campaigns).

Claude Frontforge

Build interface design with craft and consistency.

Scope

Use for: Dashboards, admin panels, SaaS apps, tools, settings pages, data interfaces.

Not for: Landing pages, marketing sites, campaigns. Redirect those to /frontend-design.

Before Writing Code

State your design choices first. This keeps thinking deliberate.

CopyDirection: [what this should feel like]
Depth: [borders / subtle shadows / layered]
Spacing: [base unit]

Then write the code.

Design Principles

Spacing

Pick a base unit and stick to multiples. Consistency matters more than the specific number. Random values signal no system.

Padding

Keep it symmetrical. If one side is 16px, others should match unless there's a clear reason.

Depth

Choose ONE approach and commit:

• Borders-only — Clean, technical. For dense tools.
• Subtle shadows — Soft lift. For approachable products.
• Layered shadows — Premium, dimensional. For cards that need presence.

Don't mix approaches.

Border Radius

Sharper feels technical. Rounder feels friendly. Pick a scale and apply consistently.

Typography

Headlines need weight and tight tracking. Body needs readability. Data needs monospace. Build a hierarchy.

Color

Gray builds structure. Color communicates meaning — status, action, emphasis. Decorative color is noise.

Animation

Fast micro-interactions (~150ms), smooth easing. No bouncy/spring effects.

Controls

Native <select> and <input type="date"> can't be styled. Build custom components.

---

Avoid

• Dramatic drop shadows
• Large radius on small elements
• Pure white cards on colored backgrounds
• Thick decorative borders
• Excessive spacing (>48px margins)
• Gradients for decoration
• Multiple accent colors

---

Self-Check

Before finishing:

• Did I think about what this product needs, or default?
• Is my depth strategy consistent throughout?
• Does every element feel intentional?

The standard: looks designed by someone who obsesses over details.

After Completing a Task

When you finish building something, always offer to save:

Copy"Want me to save these patterns for future sessions?"

If yes, write to .frontforge/system.md:

• Direction and feel
• Depth strategy (borders/shadows/layered)
• Spacing base unit
• Key component patterns with specific values

This compounds — each save makes future work faster and more consistent.

---

Workflow

Communication

Be invisible. Don't announce modes or narrate process.

Never say: "I'm in ESTABLISH MODE", "Let me check system.md..."

Instead: Jump into work. State suggestions with reasoning.

Suggest + Ask

Lead with your recommendation, then confirm:

Copy"This feels like a data-heavy admin tool — I'd go minimal.
Tight spacing, monochrome, borders for depth."

[AskUserQuestion: "Does that direction feel right?"]

If Project Has system.md

Read .frontforge/system.md and apply. Decisions are made.

If No system.md

1. Assess context — What's the product? Who uses it?
2. Suggest + ask — State recommendation, get confirmation
3. Build — Apply principles
4. Offer to save
