What it does

Rasengan Ecosystem is an agent skill from rasengan-dev/rasenganjs. Rasengan.js ecosystem package patterns. Covers @rasenganjs/kurama (state management), @rasenganjs/image (optimized images), @rasenganjs/theme (light/dark/system), @rasenganjs/i18n (internationalization), @rasenganjs/kage-demo (guided tours), and @rasenganjs/mdx (MDX content). Use when integrating ecosystem packages into a Rasengan.js project.

Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Frontend & Design, covering Internationalization, State management and Markdown. The repository describes itself as: Rasengan.js is a full-stack meta-framework for React — SSR, SSG, and a built-in backend, running anywhere from Node.js to the edge, without compromising on performance. The licence is MIT.

What it can do on your machine

Read from SKILL.md and the folder at commit 3fb89eb. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are typescript).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Rasengan Ecosystem loads about 1.5k tokens when it runs. Until then it costs about 91 tokens; SKILL.md has 316 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~91
When it runs · the whole SKILL.md, loaded when a task matches: ~1.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Rasengan.js Ecosystem Package Patterns

When to Activate

Adding state management with @rasenganjs/kurama
Optimizing images with @rasenganjs/image
Implementing light/dark/system theming with @rasenganjs/theme
Adding internationalization with @rasenganjs/i18n
Setting up MDX content with @rasenganjs/mdx
Creating guided product tours with @rasenganjs/kage-demo

State Management — @rasenganjs/kurama

import { createStore } from '@rasenganjs/kurama';

const useStore = createStore(({ set }) => ({
  count: 0,
  increment: () => set(state => ({ count: state.count + 1 })),
  reset: () => set({ count: 0 }),
}));

// In a component:
function Counter() {
  const count = useStore(state => state.count);
  const increment = useStore(state => state.increment);
  return <button onClick={increment}>{count}</button>;
}

// Subscribe to multiple values:
const { count, increment } = useStore();

Rules:

Create stores outside components to avoid re-creation on re-render
Use selectors (useStore(state => state.count)) for granular subscriptions and to avoid unnecessary re-renders
Call set() with a partial state or updater function (Zustand-like API)

Image Optimization — @rasenganjs/image

tsx

import { Image } from '@rasenganjs/image';

<Image
  src="/hero.jpg"
  alt="Hero image"
  width={1200}
  height={600}
  placeholder="blur" // or "wave"
  lazy // enable lazy loading
/>;

Rules:

Always provide width and height to prevent Cumulative Layout Shift (CLS)
Use placeholder="blur" for production — generates a blurred placeholder
Use placeholder="wave" for a lighter, animated wave placeholder
Use lazy prop to defer offscreen images (recommended for most images)
Import from @rasenganjs/image, not a generic <img> tag

Theming — @rasenganjs/theme

tsx

import { ThemeProvider, useTheme } from '@rasenganjs/theme';

// Wrap in root App component:
<ThemeProvider defaultTheme="system">
  <Component router={AppRouter}>{children}</Component>
</ThemeProvider>;

// In any component:
function ThemeToggle() {
  const { theme, setTheme } = useTheme();
  return (
    <button onClick={() => setTheme(theme === 'dark' ? 'light' : 'dark')}>
      {theme === 'dark' ? '☀️' : '🌙'}
    </button>
  );
}

Rules:

Wrap at the App root level (inside src/main.tsx)
defaultTheme="system" respects OS preference (recommended)
Theme is persisted to localStorage automatically
useTheme() returns { theme, setTheme, toggleTheme }

Internationalization — @rasenganjs/i18n

tsx

import { I18nProvider, useLocale, useTranslation } from '@rasenganjs/i18n';

// Wrap in root App component:
<I18nProvider defaultLocale="en" locales={['en', 'fr', 'de']}>
  <Component router={AppRouter}>{children}</Component>
</I18nProvider>;

// Translate in components:
function Greeting() {
  const { t } = useTranslation();
  return <h1>{t('welcome')}</h1>;
}

// Switch locale:
function LocaleSwitcher() {
  const { locale, setLocale } = useLocale();
  return (
    <select value={locale} onChange={(e) => setLocale(e.target.value)}>
      <option value="en">English</option>
      <option value="fr">Français</option>
    </select>
  );
}

Rules:

Locale is auto-detected from URL by default; setLocale updates the URL
Use flat key structures for translation files (e.g., { "welcome": "Hello" })
Wrap I18nProvider at the App root, inside src/main.tsx
useTranslation() loads translations for the current locale automatically

Guided Tours — @rasenganjs/kage-demo

Creates interactive step-by-step tours and onboarding experiences:

tsx

import KageDemoContainer, {
  useKageDemo,
  KageDemoStep,
} from '@rasenganjs/kage-demo';
import Step01 from '@/components/demo/step-01';
import Step02 from '@/components/demo/step-02';

const steps: KageDemoStep[] = [
  {
    target: '#get-started',
    render: (props) => <Step01 {...props} />,
  },
  {
    target: '#end',
    render: (props) => <Step02 {...props} />,
  },
];

export default function Page() {
  const props = useKageDemo(steps);

  return (
    <section>
      <KageDemoContainer {...props} />
      <button id="get-started">Get Started</button>
      <button onClick={props.start}>Start tour</button>
      <p id="end">End demo</p>
    </section>
  );
}

Step Component Props

interface StepProps {
  next: () => void; // go to next step
  prev: () => void; // go to previous step
  end: () => void; // end the tour
}

Core API

API	Description
`KageDemoContainer`	Main container — renders overlay and spotlight on the target element
`useKageDemo(steps)`	Hook that initializes the tour system. Returns `{ start, end, ... }`
`KageDemoStep`	`{ target: string; render: React.FC<StepProps> }` — CSS selector + step component

Rules:

Define steps with a target CSS selector and a custom render component for each step
Each step component receives next, prev, end callbacks for navigation
Call props.start to begin the tour (e.g., from a "Start tour" button)
The container renders a spotlight effect over the target element automatically
Steps are type-safe with full TypeScript inference

Rules:

@rasenganjs/kage-demo uses CSS selectors for element targeting — ensure target IDs/classes exist in the DOM
All ecosystem packages require "type": "module" in package.json
