antigravity-superpowers: Skill for Claude Code

.agent/skills/frontend-design/SKILL.md

frontend-design is a skill for Claude Code, Codex from bonnguyenitc/antigravity-superpowers. It costs 46 tokens per session (1,624 once invoked), scanned A, original, MIT.

A design guide for building polished web interfaces, pages, and applications with a deliberate visual direction and working code.

In plain words
What is it for?
Use it when creating frontend components or full web pages where layout, typography, visual style, and overall design quality matter.
Why use it?
It helps avoid generic-looking interfaces by requiring context about the audience, use cases, brand tone, and a clear design direction before implementation.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one.

This is bonnguyenitc/antigravity-superpowers's own configuration. It tells Claude Code and Codex how to work on antigravity-superpowers itself, so it is not a mod to install elsewhere.

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

frontend-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 12d 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.

Frontend Design

This skill guides creation of distinctive, production-grade frontend interfaces that avoid generic "AI slop" aesthetics. Implement real working code with exceptional attention to aesthetic details and creative choices.

Context Gathering Protocol

Design skills produce generic output without project context. Before doing any design work, confirm:

  • Target audience: Who uses this product and in what context?
  • Use cases: What jobs are they trying to get done?
  • Brand personality/tone: How should the interface feel?

Gathering order:

  1. Check current instructions: If your loaded instructions contain a Design Context section, proceed immediately.
  2. Check .impeccable.md: If it exists in the project root and has context, use it.
  3. Ask the user: If neither source has context, ask these 3 questions before proceeding.

Design Direction

Commit to a BOLD aesthetic direction before writing any code:

  • Purpose: What problem does this interface solve? Who uses it?
  • Tone: Pick an extreme — brutally minimal, maximalist chaos, retro-futuristic, organic/natural, luxury/refined, playful/toy-like, editorial/magazine, brutalist/raw, art deco/geometric, soft/pastel, industrial/utilitarian
  • Differentiation: What makes this UNFORGETTABLE? What's the one thing users remember?

CRITICAL: Choose a clear conceptual direction and execute with precision. Bold maximalism and refined minimalism both work — the key is intentionality, not intensity.

Implement working code that is:

  • Production-grade and functional
  • Visually striking and memorable
  • Cohesive with a clear aesthetic point-of-view
  • Meticulously refined in every detail

Frontend Aesthetics Guidelines

Typography

See typography reference for scales, pairing, and loading strategies.

Choose fonts that are beautiful, unique, and interesting. Pair a distinctive display font with a refined body font.

DO: Use a modular type scale with fluid sizing (clamp()) DO: Vary font weights and sizes to create clear visual hierarchy DON'T: Use overused fonts — Inter, Roboto, Arial, Open Sans, system defaults DON'T: Use monospace typography as lazy shorthand for "technical/developer" vibes DON'T: Put large icons with rounded corners above every heading

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
