Live repository

Not pinned. Installing fetches whatever the repository holds at the time you run the command.

No human has reviewed this code. The checks below are a static scan of the files at one commit — nobody has run this skill or judged whether it works. A skill runs with whatever access you give your agent, so read the source before you install it.

Automated safety checks

scanned

This skill passed all 6 checks. We read its files at one commit and looked for the things that make a skill dangerous to run — not for whether it works.

  • Declares what it does: passed

    SKILL.md parses and declares a name and a description.

    SKILL.md exists, its frontmatter parses, and it declares a name and a description.

  • No undeclared network calls: passed

    Makes no network calls.

    Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.

  • No obfuscated payloads: passed

    No encoded or obfuscated payloads.

    No base64, hex or compressed blob is decoded and then executed, and no encoded shell commands.

  • No credential access: passed

    Reads no keys, tokens, keychains or credential files.

    Neither the code nor the SKILL.md instructions read SSH keys, cloud credentials, keychains, token stores, browser cookie databases or dotfiles that hold secrets.

  • No pipe-to-shell installers: passed

    No pipe-to-shell or download-and-run installers.

    No `curl … | sh` pattern, in the code or in the instructions, that runs code fetched at run time.

  • Pinned to a commit: passed

    Scanned sergiodxa/agent-skills at 40e21b4618.

    The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

About this skill

What it does

This skill provides guidance on implementing internationalization (i18n) in React Router applications using remix-i18next. It focuses on best practices for setting up middleware, structuring locale resources, managing namespaces, detecting and persisting user locales, and ensuring synchronization between the client and server. The goal is to create a type-safe and efficient i18n setup within Remix applications.

When to use it

  • You're building a React Router application and need to add internationalization support.
  • You’re integrating remix-i18next middleware into your Remix project.
  • You want to implement language switching or automatic locale detection for users.
  • Your application serves localized resources from an API endpoint like /api/locales.

Key capabilities

  • Configuration of createI18nextMiddleware with type-safe resource loading.
  • Structuring locale resources per language and re-exporting them.
  • Strategies for managing namespaces (single vs. multiple).
  • Implementation of locale detection using cookies, sessions, or a database as the source of truth.
  • Synchronization of the user's selected locale across client and server environments.

Example prompts

  • "How do I configure createI18nextMiddleware for my Remix app?"
  • "What’s the recommended structure for organizing my locale resource files?"
  • "Can you show me an example of how to implement language switching using a cookie?"
  • “Explain how to sync the root locale with the <html lang dir> attribute.”

Tips & gotchas

  • Critical Setup: Pay close attention to the setup-middleware and locale-detection rules, as they are crucial for a functional i18n setup.
  • Namespace Strategy: Consider whether your application benefits from using multiple namespaces based on its size and complexity.
  • Locale Persistence: Prioritize cookie or session storage for speed while maintaining a database as the definitive source of truth for locale preferences.
