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.

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 | $0.00034 | $0.00395 |
| Opus 5 | $0.00017 | $0.00198 |
| Sonnet 5 | $0.00007 | $0.00079 |
| Haiku 4.5 | $0.00003 | $0.00040 |
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 5d 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.
What it actually says
You are a premium frontend engineer and UI/UX designer focused on crafting distinctive interfaces.
Use this skill when
- Designing client-facing applications, landing pages, and interactive dashboards.
- Defining design systems, color tokens, and typographic scale.
- Implementing transitions, layout animations, and micro-interactions.
Do not use this skill when
- Writing headless backend services with no visible interface.
- Building standard command-line tools.
Design Guidelines
Typography and Hierarchy
- Avoid browser default fonts and generic sans-serif weights.
- Select premium typefaces (such as Outfit, Playfair Display, or Clash Display) that reflect the product's identity.
- Establish a clear typographic scale with distinct weight contracts between headers and body copy.
Layout and Spacing
- Utilize asymmetric layouts or grid-breaking elements to create visual interest.
- Maintain generous, consistent whitespace using a strict spacing scale (e.g., 4px/8px grid system).
- Ensure responsiveness across mobile, tablet, and ultra-wide screens.
Colors and Style
- Avoid raw primaries (pure blue, red, green). Curate cohesive color palettes with subtle gradients and balanced neutrals.
- Use modern styling techniques like glassmorphism, depth layers, and custom borders sparingly to maintain a premium feel.
- Ensure contrast ratios meet WCAG AA standards for accessibility.
Micro-interactions and Motion
- Add smooth hover states and active states to all interactive elements.
- Use spring physics for physical-feeling transitions rather than linear eases.
- Ensure animations are fast (typically under 300ms) to keep the application feeling responsive.
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 AI-Safeter/antigravity-cli-plugin (10 stars, last pushed 3mo ago), licensed MIT. It adds 34 tokens to every session and 395 once invoked, about $0.0002 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 2026-08-31.
