What it does
I18n is an agent skill from MatrixAges/polywise. Guides internationalization (i18n) implementation using i18next with TypeScript. Triggered when handling localization, translation files, or multilingual support.
Its SKILL.md is about 900 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 and Translation. It works with TypeScript. The repository describes itself as: The open source agentic content system to make your contents alive. Self-hosted on any platform. ◑. The licence is MIT.

Workflow steps
4 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit f8d2320. 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
I18n loads about 898 tokens when it runs. Until then it costs about 42 tokens; SKILL.md has 223 words of instructions outside code blocks.
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.

i18n Internationalization Guide
This skill provides mandatory specifications for implementing internationalization using i18next in this project.
1. Architecture Overview
The project adopts a modular i18n structure:
- i18next: Core internationalization library.
- TypeScript: Provides complete type safety protection for translation keys.
- Modular Structure: Translation copy is organized by functionality/module.
- Dual-end Support: Simultaneously supports app (renderer process) and desktop (main process).
2. Translation File Structure
2.1 Basic Translation Module
// packages/app/locales/en/global.ts
export default {
notice: 'Notice',
edit: 'Edit',
add: 'Add',
save: 'Save',
remove: 'Remove',
remove_confirm:
'Confirm removal? Deleting this item will also delete the corresponding local file. Please proceed with caution!'
}2.2 Namespace Module
// packages/app/locales/en/app.ts
export default {
module: {
chat: 'Chat',
research: 'Research',
agent: 'Agent'
},
workspace: {
title: 'Workspace',
name_placeholder: 'A unique name'
}
}2.3 Regional Language Entry Point
// packages/app/locales/en/index.ts
import ai from './ai'
import app from './app'
import global from './global'
export default {
translation: {
...global,
app,
ai
}
} as const // ✅ Must use as const to ensure TypeScript type inference3. Steps for Adding New Translations
3.1 Adding New Module Translation
// Step 2: Add to entry index
// packages/app/locales/en/index.ts
import newFeature from './newFeature'
// Step 1: Create new translation file (English and Chinese must be created simultaneously)
// packages/app/locales/en/newFeature.ts
export default {
title: 'New Feature',
description: 'This is a new feature description'
}
// packages/app/locales/zh-cn/newFeature.ts
export default {
title: '新功能',
description: '这是新功能描述'
}
export default {
translation: {
// ... others
newFeature // Register new module
}
} as const4. Constraints and Best Practices
4.1 Naming Conventions
- Keys: Translation keys must use
snake_case. - Structure: Organize key names hierarchically by functionality or component.
- Consistency: Must maintain completely consistent key name structure across all language files.
4.2 Code Style Requirements
- No Comments: Do not add any comments to translation files.
- Default Export: Always use
export defaultto export translation objects. - Type Safety: In regional language index exports, always use
as const. - Flat Structure: Keep translation objects as flat as possible (nesting should not exceed 3 levels).
4.3 Dynamic Content and Interpolation
// In translation file
export default {
welcome_message: 'Welcome, ${name}!',
item_count: 'You have ${count} items'
}
// In component
const { t } = useTranslation()
t('welcome_message', { name: 'John' })4.4 Quality Guidelines
- Translation Completeness: In all supported language files, all keys must have corresponding translations.
- Context: When words are ambiguous, accurate translations must be provided based on context.
- Avoid Hardcoding: In React components, never hardcode visible Chinese or English characters; they must be extracted to locale files.
