frontend-frontier

frontend-frontier is a skill for Claude Code, Codex from Kevin-Liu-01/Agent-Machines. It costs 53 tokens per session (1,992 once invoked), scanned A, original, MIT.

A guide for creating distinctive web interfaces with a deliberate visual style, motion, depth, and design system. It covers landing pages, dashboards, documentation sites, and other frontends.

In plain words
What is it for?
It is for planning and building branded pages, animation systems, parallax or 3D scenes, shader effects, and reusable design tokens while considering readability, performance, and reduced-motion settings.
Why use it?
It helps avoid generic layouts and disconnected visual effects by setting a clear design direction before implementation.

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-frontier 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 2mo 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 Frontier

Use this skill when the job is not "make a page" but "make a page that actually has a point of view."

This skill is for:

  • unique landing pages and marketing sites
  • AI, devtools, and B2B SaaS frontends that need stronger taste
  • animation systems, scroll choreography, parallax, 3D, shaders, and hero scenes
  • design-system authoring, tokens, and consistency guardrails
  • turning loose inspiration into implementation-ready direction

Default stance

  • Do not drift into generic SaaS chrome.
  • Do not default to Inter, Roboto, shadcn, or arbitrary Tailwind soup unless the existing product already does.
  • Pick one art-direction thesis, one motion thesis, and one depth thesis before writing UI.
  • Build tokens before polishing components.
  • Treat motion as a system, not garnish.
  • CSS is substrate, not strategy. Use it for tokens, layout, fallbacks, and trivial states, not as the default animation architecture.
  • Default to a frontier stack: Tailwind v4 @theme, Motion, GSAP, Lenis, React Three Fiber, shaders/WebGL/WebGPU, and React transitions where appropriate.
  • Preserve performance, readability, and prefers-reduced-motion.
  • Sweat the micro-details. Great UI usually comes from many tiny correct choices compounding.

Workflow

  1. Lock the art direction.

Read references/aesthetic-systems.md.

Choose one primary mode:

  • editorial technical
  • cinematic 3D
  • architectural blueprint
  • neo-brutalist
  • experimental lab
  • premium AI SaaS

Write a 3-5 line direction covering:

  • visual thesis
  • type pairing
  • palette
  • surface treatment
  • motion grammar
  1. Choose the methodology lens.

Read references/design-methodology-atlas.md.

Pick:

  • one discovery methodology
  • one system methodology
  • one evaluation methodology
  1. Build the token system.

Read references/design-system-and-tokens.md.

Define:

  • color tokens
  • spacing scale
  • radii
  • shadows
  • border weights
  • type scale
  • z-index and blur tokens
  • motion tokens

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.
