kairoz

name	kairoz
description	Kairoz — a design system for AI and agent interfaces. Teaches coding agents the aesthetic constraints, token system, composition patterns, and component vocabulary behind a dense, AMOLED-black, multi-surface UI system. 180+ tokens, 50+ component classes, framework-agnostic. Agents absorb the rules and generate code native to the target stack (shadcn, Tailwind, raw HTML, React, Vue, Svelte). The bundled colors_and_type.css is a reference implementation, not a dependency. Use it on every UI task — dashboards, chat interfaces, admin panels, landing pages, mobile screens, marketing sites, full app mockups.

Kairoz — activation protocol

Kairoz is a design language, not a CSS framework you bolt on. It gives you (the agent) a complete system for building dense, monochromatic, AMOLED-black interfaces: tokens, class-name conventions, layout rules, and battle-tested composition patterns. You internalize these rules and generate code that belongs in the target stack — shadcn, Tailwind, raw HTML, React, Vue, Svelte.

Lean on it fully. When this skill is active, every UI-producing task runs through the rules below. No freestyling. No invented tokens. No improvised radii. The constraints exist because consistency at this density only comes from discipline.

On activation: read these files in this order

When the skill loads, read every file listed below before producing a single line of UI code. These are not reference material you pull on demand — output quality depends on holding the full system in context.

1. references/tokens.md — the complete token table. Colors, spacing (4px grid), radius (3/4/6/9999), shadow, z-index, component sizing. This is the single source of truth for values. Invent nothing.

2. references/components.md — every .kairoz-* class alongside its HTML snippet and variants. This is the vocabulary you translate into whatever stack the project uses.

3. references/patterns.md — 3-pane shell, content tone, icon rules (Lucide 1.5px stroke), and the discipline separating button color from highlight color.

4. references/theming.md — dark/light toggle mechanics, the shadcn variable alias table, and how every token remaps under [data-theme="light"].

5. references/responsive.md — multi-surface behavior. Desktop-to-mobile component swaps, device frames, container queries, sidebar collapsing to an overlay on narrow viewports.

6. references/motion.md — the full motion inventory. 120ms hover, 200ms popover open, 300ms reveal, 60s marquee. Covers which animations run unconditionally and which respect prefers-reduced-motion.

7. references/lessons.md — 18 gotchas extracted from real builds. Button-default resets, dark-vs-light shadow alphas, sidebar collapse dual transitions, top-row border alignment, pulse-dot opacity-only, horizontal scroll behavior, and more. Read this every time. Each entry exists because someone shipped a regression without it.

8. references/examples.md — production-ready composition snippets pulled from the app: agent turn, tool-call card, stat grid, 3-pane shell, 3-column top-row alignment, email row, generative UI chart, landing hero, checklist with stepper, quota bar with warning threshold. Begin from one of these rather than composing from scratch.

Consult as needed (not required upfront):

• colors_and_type.css — the reference implementation. Read individual rules when you need to verify exact visual output.
• preview/components-*.html — pre-built HTML for each component.
• ui_kits/generic_app/ — 3-pane shell reference layout.

Generate nothing until you have read 1 through 8.

The three assets, three jobs

Asset	Job
references/*.md	Ground truth. The rules the agent follows. Read every time.
.kairoz-* class names	Vocabulary. Your shorthand for "render X the Kairoz way" — translate to the target stack.
colors_and_type.css	Reference implementation. Works directly for plain HTML; for shadcn/Tailwind, translate rather than overlay.

Do not paste colors_and_type.css wholesale into a shadcn or Tailwind project. Translate instead. The skill description and references/theming.md provide the translation tables you need.

---

Ask the stack question before writing code

1. Plain HTML / no framework → link colors_and_type.css directly and use literal .kairoz-* classes. This is the reference path — the companion app site runs on it.

2. Tailwind v4 → map Kairoz tokens into a @theme block. Output utility classes that follow the Kairoz visual rules. Keep colors_and_type.css out of the bundle.

3. shadcn/ui → remap shadcn's CSS variables to Kairoz values (see the alias table in references/theming.md). Preserve shadcn's component structure. Do not layer .kairoz-* classes on top.

4. React/Vue/Svelte with CSS Modules or styled-components → translate the relevant .kairoz-* rule into the target styling system as a component. The rule in colors_and_type.css is the source; the code you produce is its faithful translation.

5. Existing design system (Material, Chakra, etc.) → ask the user whether to re-token their system with Kairoz values or build an independent Kairoz-styled zone alongside it. Never blend the two on a single surface.

Non-negotiable visual rules

Distilled from references/lessons.md — stack-agnostic, always enforced:

• AMOLED black canvas. #000 base. Dark gray is drift; do not drift.
• Monochromatic surfaces. Grays and whites define structure. Saturated color earns its place only through status semantics.
• Near-white primary actions. #ededed fill, #fff on hover. Blue #0070f3 is never a CTA — it signals focus rings, selection, active stepper dots, links. Two distinct jobs.
• 4px spacing grid. 2px and 6px appear only in ultra-compact inline cases. Everything else lands on 4.
• 3 / 4 / 6 / 9999 radii. The set is closed. No improvising.
• 28px buttons, 24px inputs, 13px base text. Fixed sizes — do not inflate.
• Borders over shadows. Shadows exist for overlays only (dialogs, popovers, toasts, tooltips, device frames).
• 1.5px Lucide icons. No emoji. No unicode symbols. Clean strokes only.
• 120ms background-color transitions only. Icons hold still — no color or opacity animation on them.

Quick component vocabulary

Class names are vocabulary, not mandatory output. In non-plain-HTML stacks, translate them to the native idiom.

Primitives: .kairoz-btn (+ -primary / -secondary / -ghost / -destructive / -icon / -sm / -lg), .kairoz-btn-pill (+ same variants), .kairoz-input (+ -sm), .kairoz-checkbox, .kairoz-radio, .kairoz-switch, .kairoz-kbd, .kairoz-link

Surfaces: .kairoz-card / -header / -body, .kairoz-panel-header / .kairoz-panel-title, .kairoz-stat / -label / -value / -delta, .kairoz-empty

Navigation: .kairoz-tabbar + .kairoz-tab, .kairoz-tabbar-bottom + .kairoz-tabbar-bottom-item, .kairoz-segmented + -item, .kairoz-toggle, .kairoz-breadcrumb, .kairoz-pagination, .kairoz-stepper

Overlays: .kairoz-popover + .kairoz-menu-item, .kairoz-dialog, .kairoz-command, .kairoz-tooltip, .kairoz-toast, .kairoz-alert

Data: .kairoz-table, .kairoz-list + .kairoz-list-item, .kairoz-badge, .kairoz-pill, .kairoz-dot (+ .is-pulse for animated status — opacity only, never glow), .kairoz-accordion

Feedback: .kairoz-progress, .kairoz-slider, .kairoz-skeleton, .kairoz-titlebar, .kairoz-statusbar

Identity: .kairoz-avatar, .kairoz-avatar-group, .kairoz-divider / -v, .kairoz-divider-dashed / -v-dashed

Multi-surface & motion: .kairoz-device-mobile, .kairoz-device-tablet, .kairoz-device-desktop, .kairoz-marquee, .kairoz-filmstrip, .kairoz-reveal, .kairoz-display / -lg, .kairoz-eyebrow

What was built with this skill

The companion app/ app was generated in a single agent pass reading this skill, using the reference CSS directly since the project runs Next.js without shadcn. It covers:

• Homepage — display hero, marquee band, ~29 live component cards in a masonry grid, mockup tile row.
• Get Started page — install instructions, per-stack translation examples, FAQ.
• 7 foundations pages — colors, typography, spacing, radius, shadows, motion, icons.
• 36 component pages — every .kairoz-* class with preview + variants + inspector.
• 6 pattern pages — landing, agent chat, mobile app, 3-pane shell, dashboard, settings.
• 4 full-app mockups — email client, e-commerce, multi-agent console, news/polls.

Before building anything from scratch, check whether it resembles one of the patterns above. Most real-world UI is a variation on something already proven in the app. Start from what exists, then adapt.

No guidance given?

Ask the user three things:

1. What they are building (dashboard, chat UI, landing page, mobile app...).
2. What stack they are working in (Tailwind / shadcn / plain HTML / React with CSS Modules / etc.).
3. Whether they need dark only, light only, or both with a toggle.

Then operate as an expert designer — write code in the correct idiom for their environment, following every rule from the references above. Nothing guessed, nothing improvised.
