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 | $0.00048 | $0.01988 |
| Opus 5.5 | $0.00019 | $0.00795 |
| Sonnet 5.5 | $0.00010 | $0.00398 |
| Haiku 4.5 | $0.00005 | $0.00199 |
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 15d 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 — 190 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 feel deliberate, premium, and current. Implement real working code with exceptional attention to aesthetic details and creative choices.
Design Thinking
Before coding, understand the context and commit to a clear aesthetic direction.
Output three things as text before coding:
- Visual thesis: one sentence describing mood, material, and energy (e.g., "brutally minimal dark interface with surgical precision" or "high-contrast editorial magazine feel with oversized serif headlines")
- Content plan: the sections in order (hero, support, detail, final CTA for a marketing page; the working surface first for product UI)
- Interaction thesis: 2-3 motion ideas that change the feel of the page
For each, consider:
- Purpose: What problem does this interface solve? Who uses it?
- Tone: Pick a direction and commit. Brutally minimal, maximalist, retro-futuristic, organic, luxury, playful, editorial, brutalist, art deco, soft pastel, industrial. These are starting points; design one true to the vision.
- Constraints: Framework, performance, accessibility requirements.
- Differentiation: What makes this unforgettable? What's the one thing someone remembers?
Match ambition to context. A brand landing page warrants bold, expressive choices. A dashboard warrants calm restraint. Both require intentionality.
Then implement working code (HTML/CSS/JS, React, Vue, etc.) that is production-grade, visually striking, cohesive, and meticulously refined.
Beautiful Defaults
- Start with composition, not components.
- Prefer a full-bleed hero or full-canvas visual anchor.
- Make the brand or product name the loudest text.
- Keep copy short enough to scan in seconds.
- Use whitespace, alignment, scale, cropping, and contrast before adding chrome.
- Limit the system: two typefaces max, one accent color by default.
- Default to cardless layouts. Use sections, columns, dividers, lists, and media blocks instead.
- Treat the first viewport as a poster, not a document.
- Each section gets one job, one dominant visual idea, and one primary takeaway or action.
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 tobihagemann/turbo (417 stars, last pushed 4d ago), licensed MIT. It adds 48 tokens to every session and 1,988 once invoked, about $0.0002 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.
