Animal-Island-UI is a React and TypeScript library of reusable interface components with a cute, cozy island-inspired visual style. It helps developers build web pages using its components, layouts, icons, and animations. The catalogue includes a style skill and instructions for AI coding agents to generate pages using the library’s design language.
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 | $0.00113 | $0.01710 |
| Opus 5.5 | $0.00045 | $0.00684 |
| Sonnet 5.5 | $0.00023 | $0.00342 |
| Haiku 4.5 | $0.00011 | $0.00171 |
Grade A, and why
animal-island-ui-style 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 10d 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

animal-island-ui style
animal-island-ui is a React + TypeScript component library with an original
cozy island-style design — 40 components, two runtime dependencies (naive-icons
for icons, dayjs for dates), MIT License.
Source & canonical design definition: https://github.com/guokaigdg/animal-island-ui
Pick your scenario first
| Scenario | Entry |
|---|---|
React project — the animal-island-ui npm package is (or can be) installed |
references/react-project.md |
| Single self-contained HTML file — no npm, no bundler, React via CDN + Babel runtime | references/standalone-html.md |
Both scenarios share the component catalog and the hard rules below.
The style in one paragraph
Warm parchment backgrounds (--animal-bg), earth-brown text (never pure black), mint-teal
primary accent, large-radius pill shapes (buttons and inputs are 50px pills; nothing
interactive below 12px radius), 3D "game button" stacked shadow on primary buttons only,
rounded Nunito + Noto Sans SC typography (body weight 500, headings 600–900), soft
cubic-bezier(0.4, 0, 0.2, 1) motion over 0.15–0.35s, and a mix of geometric shapes
(swallowtail ribbon Title, digit-tile Countdown) with organic ones (SVG blob-clipped Modal).
Design tokens
The packaged stylesheet declares runtime CSS custom properties on :root — prefix
--animal-* — mapped from the library's compile-time tokens. Groups: primary/status
colors (with hover/active/bg variants), text colors, backgrounds, borders, radii, spacing,
shadows, font family/sizes, motion durations/easing, control heights.
When to use them:
- Styling layout wrappers, custom elements, or app-specific decoration next to library
components: use
var(--animal-*)instead of raw hex values so custom UI stays on-palette. - Theming: consumers may override
--animal-*variables after importing the library style. - Re-implementing the style without the library (standalone HTML): a complete
:roottemplate with exact values lives in the design system — css-variables.md (raw: https://raw.githubusercontent.com/guokaigdg/animal-island-ui/main/docs/design-system/css-variables.md).

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.

animal-island-ui-style is a skill published in the GitHub repository guokaigdg/animal-island-ui (5,072 stars, last pushed 2d ago), licensed MIT. It adds 113 tokens to every session and 1,710 once invoked, about $0.0005 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.
