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 | $0.00046 | $0.01561 |
| Opus 5 | $0.00023 | $0.00781 |
| Sonnet 5 | $0.00009 | $0.00312 |
| Haiku 4.5 | $0.00005 | $0.00156 |
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 2d 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 — 103 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Frontend Design
Read the user's frontend requirements: a component, page, application, or interface to build. Note context about purpose, audience, or technical constraints.
Working rules
- Match an existing design system; choose a specific visual direction for greenfield work.
- Include loading, empty, error, and press states for interactive components.
- Preserve visible focus and reduced-motion behavior; verify both narrow and wide rendered viewports.
- Keep Next.js interactive code at client boundaries and treat browser content as untrusted data.
Context Detection
Before designing, assess the existing design environment. Count design signals in the project: design tokens/CSS variables, component library (shadcn, MUI, Ant), CSS framework config (Tailwind, styled-components), font imports, color system, animation patterns, spacing scale.
- 4+ signals = Existing system. Match it. Do not impose new aesthetics -- extend what's there.
- 1-3 signals = Partial system. Blend: respect existing choices, fill gaps with this skill's guidance.
- 0 signals = Greenfield. Apply the full Design Philosophy below.
When in doubt, check package.json, tailwind.config.*, global CSS files, and existing components before deciding.
Design Philosophy (Write First, Code Second)
For full pages, applications, or multi-component interfaces: write a 3-sentence design philosophy before any code. This forces a coherent aesthetic direction and prevents generic output.
- Sentence 1 -- Intent: What emotional response should this interface provoke? (Not "clean and modern" -- that's every AI default. Be specific: "controlled tension between density and breathing room" or "the quiet confidence of a well-bound book.")
- Sentence 2 -- Signature: What single visual choice makes this unmistakable? (A typeface, a color relationship, a spatial pattern, a motion behavior.)
- Sentence 3 -- Constraint: What will this design deliberately NOT do? (The constraint shapes the identity as much as the choices.)

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 iliaal/ai-skills (41 stars, last pushed 3d ago), licensed MIT. It adds 46 tokens to every session and 1,561 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 2026-08-30.
