What it does

I18n Localization is an agent skill from WrongStack/WrongStack. Implement localization with translated messages, locale-aware formatting and adaptable layouts. Use when supporting multiple languages, RTL or regional formats; preserve message identity and test realistic translated content rather than only replacing labels.

Its SKILL.md is about 850 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. The repository describes itself as: An AI coding agent that reads your code, edits files, runs commands, and reasons through bugs — across a terminal REPL, a full-screen TUI, and a browser UI, while you keep your… The licence is MIT.

When your agent uses it

  • Supporting multiple languages
  • Regional formats
  • Preserve message identity and test realistic translated content rather than only replacing labels

Example prompts

  • “/i18n-localization”

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

  1. Model language, locale, timezone and currency as separate choices with documented fallback.
  2. Use message/plural interpolation rather than concatenating translated fragments.
  3. Keep numeric/date values structured until display; store currency/timezone semantics intentionally.
  4. Design for expansion, RTL/bidirectional text, input methods and font glyph coverage.
  5. Translate accessible names, validation/errors, email/notifications and metadata as relevant.
  6. Avoid cache leakage across locale and avoid exposing private request data during server rendering.

What it can do on your machine

Read from SKILL.md and the folder at commit a744bdc. 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.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • developer.mozilla.org
    • w3.org

    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 Localization loads about 847 tokens when it runs. Until then it costs about 69 tokens; SKILL.md has 294 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~69
When it runs · the whole SKILL.md, loaded when a task matches
~847

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 Localization

Selection card

  • Task: Implement translation, plurals and bidirectional layout. / TR: Çeviri, çoğul ve çift yönlü yerleşim uygula.
  • Start: Identify the target surface, reference, user task and existing tokens.
  • Finish: apply the acceptance checks below; report observed results and unresolved constraints.

Overview

Implement localization with translated messages, locale-aware formatting and adaptable layouts.

Use current platform Intl and the project installed localization framework. Verify framework-specific server/client locale loading before changing packages.

Rules

  1. Model language, locale, timezone and currency as separate choices with documented fallback.
  2. Use message/plural interpolation rather than concatenating translated fragments.
  3. Keep numeric/date values structured until display; store currency/timezone semantics intentionally.
  4. Design for expansion, RTL/bidirectional text, input methods and font glyph coverage.
  5. Translate accessible names, validation/errors, email/notifications and metadata as relevant.
  6. Avoid cache leakage across locale and avoid exposing private request data during server rendering.

Workflow

  1. Inventory user-visible strings and current locale routing/catalogs.
  2. Implement messages and formatting with stable keys and appropriate locale context.
  3. Test plural/zero cases, long labels, RTL and actual date/currency boundaries.
  4. Verify fallback/missing keys and server hydration/cache behavior.
  5. Run existing completeness checks and inspect representative rendered journeys.

Before returning

Locale/data semantics preserved; catalogs complete or gaps explicit; RTL/long text and accessibility checked; server/client locale consistent.

Sources

Versioned facts checked 2026-10-09; refresh authoritative sources before new installs/upgrades. Intl, W3C internationalization.

Skills in scope

  • design-system — create and maintain coherent visual tokens, themes and shared component states using the existing project system or WrongStack Design Studio.
  • accessibility — implement and review accessible user interfaces with semantic controls, keyboard and focus behavior, readable content and assistive-technology checks.
  • testing — testing contracts and verification.
  • nextjs-modern — build, migrate, and debug Next.js 16 App Router applications with React 19, Server Components, Server Actions, explicit caching, and production deployment.
