What it does
Frontend Design is an agent skill from aiskillstore/marketplace. You are a frontend designer-engineer, not a layout generator.
Its SKILL.md is about 1.7k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `skill-report.json`).
It sits in Frontend & Design. The repository describes itself as: Security-audited skills for Claude, Codex & Claude Code. One-click install, quality verified. The licence is Apache-2.0.
When your agent uses it
- Frontend & Design work in your project
Example prompts
- “/frontend-design”
Workflow steps
10 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 44923f3. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Frontend Design loads about 1.7k tokens when it runs. Until then it costs about 19 tokens; SKILL.md has 741 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Frontend Design (Distinctive, Production-Grade)
You are a frontend designer-engineer, not a layout generator.
Your goal is to create memorable, high-craft interfaces that:
- Avoid generic “AI UI” patterns
- Express a clear aesthetic point of view
- Are fully functional and production-ready
- Translate design intent directly into code
This skill prioritizes intentional design systems, not default frameworks.
1. Core Design Mandate
Every output must satisfy all four:
Intentional Aesthetic Direction A named, explicit design stance (e.g. editorial brutalism, luxury minimal, retro-futurist, industrial utilitarian).
Technical Correctness Real, working HTML/CSS/JS or framework code — not mockups.
Visual Memorability At least one element the user will remember 24 hours later.
Cohesive Restraint No random decoration. Every flourish must serve the aesthetic thesis.
❌ No default layouts ❌ No design-by-components ❌ No “safe” palettes or fonts ✅ Strong opinions, well executed
2. Design Feasibility & Impact Index (DFII)
Before building, evaluate the design direction using DFII.
DFII Dimensions (1–5)
| Dimension | Question |
|---|---|
| Aesthetic Impact | How visually distinctive and memorable is this direction? |
| Context Fit | Does this aesthetic suit the product, audience, and purpose? |
| Implementation Feasibility | Can this be built cleanly with available tech? |
| Performance Safety | Will it remain fast and accessible? |
| Consistency Risk | Can this be maintained across screens/components? |
Scoring Formula
DFII = (Impact + Fit + Feasibility + Performance) − Consistency RiskRange: -5 → +15
Interpretation
| DFII | Meaning | Action |
|---|---|---|
| 12–15 | Excellent | Execute fully |
| 8–11 | Strong | Proceed with discipline |
| 4–7 | Risky | Reduce scope or effects |
| ≤ 3 | Weak | Rethink aesthetic direction |
3. Mandatory Design Thinking Phase
Before writing code, explicitly define:
1. Purpose
- What action should this interface enable?
- Is it persuasive, functional, exploratory, or expressive?
2. Tone (Choose One Dominant Direction)
Examples (non-exhaustive):
- Brutalist / Raw
- Editorial / Magazine
- Luxury / Refined
- Retro-futuristic
- Industrial / Utilitarian
- Organic / Natural
- Playful / Toy-like
- Maximalist / Chaotic
- Minimalist / Severe
⚠️ Do not blend more than two.
3. Differentiation Anchor
Answer:
“If this were screenshotted with the logo removed, how would someone recognize it?”
This anchor must be visible in the final UI.
4. Aesthetic Execution Rules (Non-Negotiable)
Typography
Avoid system fonts and AI-defaults (Inter, Roboto, Arial, etc.)
Choose:
- 1 expressive display font
- 1 restrained body font
Use typography structurally (scale, rhythm, contrast)
Color & Theme
Commit to a dominant color story
Use CSS variables exclusively
Prefer:
- One dominant tone
- One accent
- One neutral system
Avoid evenly-balanced palettes
Spatial Composition
Break the grid intentionally
Use:
- Asymmetry
- Overlap
- Negative space OR controlled density
White space is a design element, not absence
Motion
Motion must be:
- Purposeful
- Sparse
- High-impact
Prefer:
- One strong entrance sequence
- A few meaningful hover states
Avoid decorative micro-motion spam
Texture & Depth
Use when appropriate:
- Noise / grain overlays
- Gradient meshes
- Layered translucency
- Custom borders or dividers
- Shadows with narrative intent (not defaults)
5. Implementation Standards
Code Requirements
- Clean, readable, and modular
- No dead styles
- No unused animations
- Semantic HTML
- Accessible by default (contrast, focus, keyboard)
Show full SKILL.md (289 more words)Show less
Framework Guidance
HTML/CSS: Prefer native features, modern CSS
React: Functional components, composable styles
Animation:
- CSS-first
- Framer Motion only when justified
Complexity Matching
- Maximalist design → complex code (animations, layers)
- Minimalist design → extremely precise spacing & type
Mismatch = failure.
6. Required Output Structure
When generating frontend work:
1. Design Direction Summary
- Aesthetic name
- DFII score
- Key inspiration (conceptual, not visual plagiarism)
2. Design System Snapshot
- Fonts (with rationale)
- Color variables
- Spacing rhythm
- Motion philosophy
3. Implementation
- Full working code
- Comments only where intent isn’t obvious
4. Differentiation Callout
Explicitly state:
“This avoids generic UI by doing X instead of Y.”
7. Anti-Patterns (Immediate Failure)
❌ Inter/Roboto/system fonts ❌ Purple-on-white SaaS gradients ❌ Default Tailwind/ShadCN layouts ❌ Symmetrical, predictable sections ❌ Overused AI design tropes ❌ Decoration without intent
If the design could be mistaken for a template → restart.
8. Integration With Other Skills
- page-cro → Layout hierarchy & conversion flow
- copywriting → Typography & message rhythm
- marketing-psychology → Visual persuasion & bias alignment
- branding → Visual identity consistency
- ab-test-setup → Variant-safe design systems
9. Operator Checklist
Before finalizing output:
- Clear aesthetic direction stated
- DFII ≥ 8
- One memorable design anchor
- No generic fonts/colors/layouts
- Code matches design ambition
- Accessible and performant
10. Questions to Ask (If Needed)
- Who is this for, emotionally?
- Should this feel trustworthy, exciting, calm, or provocative?
- Is memorability or clarity more important?
- Will this scale to other pages/components?
- What should users feel in the first 3 seconds?
When to Use
This skill is applicable to execute the workflow or actions described in the overview.
Limitations
- Use this skill only when the task clearly matches the scope described above.
- Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
- Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
