Curated by Skill Harbor — @sickn33's internationalization and localization playbook: core concepts (i18n vs l10n, locales, RTL), implementation patterns for React (react-i18next), Next.js (next-intl) and Python (gettext), a locale file-structure template, DO/DON'T best practices (translation keys, namespacing, pluralization, ICU message format, never concatenate translated strings), RTL support with CSS logical properties, a pre-ship checklist, common-issue solutions, and an `i18n_checker.py` script that detects hardcoded strings and missing translations. By @sickn33, listed here with credit to its creator. Honest caveats: a guidance playbook, not a translation service — it will not write your translations for you. MIT-licensed. Skill Harbor never reviews the code, review it yourself before use. Discovered via skills.sh.

Install
Prerequisites: a code project to internationalize; nothing else — the skill is guidance plus a checker script, no accounts or keys required Install "i18n and localization patterns for developers" for me. It teaches the agent @sickn33's i18n playbook: detecting hardcoded strings, managing translation keys and locale files, React/Next.js/Python patterns, RTL support, best practices and a pre-ship checklist — plus an i18n_checker.py script that finds hardcoded strings and missing translations. MIT-licensed. Repository: https://github.com/sickn33/agentic-awesome-skills/blob/main/plugins/agentic-awesome-skills-claude/skills/i18n-localization/SKILL.md 1. Fetch the SKILL.md file (and any helper files) from the repository path into a temporary folder and summarize what it does in one or two sentences. 2. Safety check: review the SKILL.md and scripts for anything suspicious (unexpected network calls, shell commands, credential harvesting). This repo should contain zero secrets in code, credentials only via the secure vault, allowed hosts declared in the SKILL.md. Verify that holds here; STOP on any red flag and tell me. 3. Install it as a skill: copy SKILL.md and its helper files into the agent's skills directory, in a folder named "i18n-localization". 4. Verify with no network calls: frontmatter valid, files in place. 5. Report what was installed, where, and what I still need to do myself (e.g. nothing — point the agent at your project when you want an i18n review). GitHub is optional: if I have a GitHub account or the gh CLI, you may use it; otherwise public access is fine. Never require it unless it's in the prerequisites above. Rules: don't touch anything outside the temp folder and the install target. If anything looks off, stop and ask me.
Questions
How do I install a build?
Every product page includes a copy-paste install prompt. Paste it into your Muse and it sets the build up for you — no manual configuration.
Where does my money go?
Straight to the seller. Skill Harbor never processes payments: checkout happens on the seller’s own page, usually Stripe.
What does the ✓ next to a creator’s name mean?
It means we confirmed the identity of the person behind the listing. It says nothing about the code itself — always check a build before installing it.
