Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00053 | $0.01992 |
| Opus 5 | $0.00026 | $0.00996 |
| Sonnet 5 | $0.00011 | $0.00398 |
| Haiku 4.5 | $0.00005 | $0.00199 |
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 11d 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.
How it starts
The opening of the file, as written. The whole thing — 232 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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
- 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
- Choose the methodology lens.
Read references/design-methodology-atlas.md.
Pick:
- one discovery methodology
- one system methodology
- one evaluation methodology
- 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.
- 11d ago First seen · 232 lines · 53 tokens per session scan A c04d6b2922e5
frontend-frontier is a skill published in the GitHub repository Kevin-Liu-01/Agent-Machines (29 stars, last pushed yesterday), licensed MIT. It adds 53 tokens to every session and 1,992 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
