Automated summary
Guides internationalization and localization: replacing hardcoded strings with translation keys, organizing locale files, handling RTL, and using Intl for dates and numbers.
Strengths
- Provides concrete examples for React, Next.js, and Python
- Includes an RTL section with CSS logical properties and a pre-release checklist
- Offers an audit script for finding hardcoded strings and missing translations
- Collects framework-agnostic best practices (namespaces, ICU, fallback)
Limitations
- Introductory content: no advanced configuration (middleware, language detection)
- The script is referenced but its implementation is not detailed in SKILL.md
- Examples are limited to three stacks
Use when adding multi-language support to an app, auditing hardcoded UI strings, or planning RTL layouts.
Not suited for advanced translation workflow automation (TMS, CI) or deep framework-specific configuration.
Security analysis
SafeThe skill is documentation-only and declares read-only tools (Read, Glob, Grep). It contains no destructive commands, secret exfiltration, obfuscated payloads, or safety-disabling instructions. The referenced i18n checker script is benign in intent and not actually executable under the declared tool permissions.
No concerns found

i18n & Yerelleştirme
Uluslararasılaştırma (i18n) ve Yerelleştirme (L10n) en iyi uygulamaları.
1. Temel Kavramlar
| Terim | Anlamı | |------|---------| | i18n | Uluslararasılaştırma - uygulamayı çevrilebilir hale getirme | | L10n | Yerelleştirme - gerçek çeviriler | | Locale | Dil + Bölge (en-US, tr-TR) | | RTL | Sağdan sola diller (Arapça, İbranice) |
2. i18n Ne Zaman Kullanılır
| Proje Türü | i18n Gerekli mi? | |--------------|--------------| | Halka açık web uygulaması | ✅ Evet | | SaaS ürünü | ✅ Evet | | Dahili araç | ⚠️ Belki | | Tek bölgeli uygulama | ⚠️ Geleceği düşün | | Kişisel proje | ❌ İsteğe bağlı |
3. Uygulama Desenleri
React (react-i18next)
import { useTranslation } from 'react-i18next';
function Welcome() {
const { t } = useTranslation();
return <h1>{t('welcome.title')}</h1>;
}
Next.js (next-intl)
import { useTranslations } from 'next-intl';
export default function Page() {
const t = useTranslations('Home');
return <h1>{t('title')}</h1>;
}
Python (gettext)
from gettext import gettext as _
print(_("Welcome to our app"))

5. En İyi Uygulamalar
YAP ✅
- Ham metin değil, çeviri anahtarları kullan
- Çevirileri özelliğe göre ad alanlarına ayır (namespace)
- Çoğullaştırmayı destekle
- Tarih/sayı formatlarını yerel ayara göre işle
- RTL'yi baştan planla
- Karmaşık dizeler için ICU mesaj formatını kullan
YAPMA ❌
- Bileşenlerde dizeleri sabit kodla (hardcode)
- Çevrilmiş dizeleri birleştir (concatenate)
- Metin uzunluğunu varsay (Almanca %30 daha uzundur)
- RTL düzenini unut
- Aynı dosyada dilleri karıştır
6. Yaygın Sorunlar
| Sorun | Çözüm | |-------|----------| | Eksik çeviri | Varsayılan dile geri dön (fallback) | | Sabit kodlanmış dizeler | Linter/denetleyici script kullan | | Tarih formatı | Intl.DateTimeFormat kullan | | Sayı formatı | Intl.NumberFormat kullan | | Çoğullaştırma | ICU mesaj formatı kullan |
7. RTL Desteği
/* CSS Mantıksal Özellikleri */
.container {
margin-inline-start: 1rem; /* margin-left değil */
padding-inline-end: 1rem; /* padding-right değil */
}
[dir="rtl"] .icon {
transform: scaleX(-1);
}

From the file to a first result
The download contains exactly the content displayed on this page. This copy may differ from the latest version in the source repository.
View the source and supporting filesThis download contains SKILL.md only. Any scripts, references, templates and dependencies are not included. Get the required files from the source, preserving their directory structure, before continuing.
1. Download the file
Download SKILL.mdFrom the root of a test project, save the file as .skill-downloads/internationalization-and-localization-i18n-l10n-mmbizk4w/SKILL.md, or use the command below. This folder is for inspecting the skill before installation.
Command for macOS/Linux or WSL: requires a POSIX shell and curl. On Windows without WSL, use the download button and create the folder manually.
mkdir -p '.skill-downloads/internationalization-and-localization-i18n-l10n-mmbizk4w' && curl --fail --show-error --location 'https://skills-guides.com/api/skills/internationalization-and-localization-i18n-l10n-mmbizk4w/download' --output '.skill-downloads/internationalization-and-localization-i18n-l10n-mmbizk4w/SKILL.md.part' && mv '.skill-downloads/internationalization-and-localization-i18n-l10n-mmbizk4w/SKILL.md.part' '.skill-downloads/internationalization-and-localization-i18n-l10n-mmbizk4w/SKILL.md'2. Check prerequisites
Read SKILL.md before using it. If it references scripts or external services, inspect them and prepare the required access in your test environment.
Tools declared by the author (check availability in your agent): Read, Glob, Grep
No recognized prerequisites section in this file. This does not mean it is self-contained: libraries, tools and access requirements may be mentioned elsewhere in the content or source repository.
The platforms on this page are catalog indications. The paths below follow tool documentation; they do not prove this skill has been run in those tools. No minimum tool version is confirmed for this listing.
3. Load the skill
After inspection, copy the complete folder into your project using one of the commands below, then open a new tool session. The command stops if a folder with the same name already exists: compare the files before replacing it.

For an agent that reads AGENTS.md, then sync the index. This command changes AGENTS.md: review the diff before using it.

4. Try a first task
Use a short, synthetic input: an API endpoint, a small document or an interface brief. In a new conversation, attach the file or give the agent its path, then adapt this request:
Read .skill-downloads/internationalization-and-localization-i18n-l10n-mmbizk4w/SKILL.md and apply its instructions to this example: [describe a test input]. Identify any missing files, dependencies or access. Produce the result requested by the skill without inventing data or running unreviewed scripts.Expected result: output matching the skill instructions, or a precise list of missing prerequisites. A read confirmation alone does not validate a first use. If an external resource is unavailable, that path remains untested.
React Hook Form Best Practices
Development
Master React Hook Form: avoid anti-patterns, manage subscriptions, and handle reset, dirty state, and controlled inputs correctly.
Emotion to Mantine Migration
Development
Migrate Emotion styled-components to Mantine components with style props and CSS modules. Use when converting .styled.tsx files or removing @emotion imports.
Scope Creep Detector
Development
Analyzes git diffs against a stated intent to detect scope creep, unrelated files, broad PRs, and oversized changes, then suggests keep, split, or justify actions.
