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 | $0.00084 | $0.00715 |
| Opus 5.5 | $0.00034 | $0.00286 |
| Sonnet 5.5 | $0.00017 | $0.00143 |
| Haiku 4.5 | $0.00008 | $0.00072 |
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 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.
How it starts
The opening of the file, as written. The whole thing — 60 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Frontend Design
Create distinctive, production-grade frontend interfaces that avoid generic "AI slop" aesthetics. Real working code with exceptional attention to aesthetic details and creative choices.
Design Thinking (Before Coding)
Commit to a BOLD aesthetic direction:
- 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
- Constraints: Technical requirements (framework, performance, accessibility)
- Differentiation: What makes this UNFORGETTABLE? What's the one thing someone remembers?
Choose a clear conceptual direction and execute with precision. Bold maximalism and refined minimalism both work — the key is intentionality, not intensity.
Frontend Aesthetics Pillars
Typography
Choose fonts that are beautiful, unique, and interesting. Avoid generic fonts like Arial, Inter, Roboto, system fonts. Pair a distinctive display font with a refined body font. Unexpected, characterful choices.
Color & Theme
Commit to a cohesive aesthetic. Use CSS variables for consistency. Dominant colors with sharp accents outperform timid, evenly-distributed palettes.
Motion
Animations for effects and micro-interactions. CSS-only for HTML, Motion library for React. High-impact moments: one well-orchestrated page load with staggered reveals creates more delight than scattered micro-interactions. Scroll-triggering and hover states that surprise.
Spatial Composition
Unexpected layouts. Asymmetry. Overlap. Diagonal flow. Grid-breaking elements. Generous negative space OR controlled density.
Backgrounds & Visual Details
Atmosphere and depth over solid colors. Gradient meshes, noise textures, geometric patterns, layered transparencies, dramatic shadows, decorative borders, custom cursors, grain overlays.
NEVER Use
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.

frontend-design is a skill published in the GitHub repository Kevin-Liu-01/Agent-Machines (29 stars, last pushed 15d ago), licensed MIT. It adds 84 tokens to every session and 715 once invoked, about $0.0003 per session on Opus 5.5. 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.
