localization-design

localization-design is a skill for Claude Code from Owl-Listener/designer-skills. It costs 49 tokens per session (1,125 once invoked), scanned A, original, MIT.

A design guide for software that supports multiple languages, writing directions, and cultural conventions. It covers longer translated text, right-to-left layouts, scripts, and locale-specific formats.

In plain words
What is it for?
Use it when designing multilingual interfaces, supporting right-to-left languages such as Arabic, handling translated buttons and containers, or adapting typography, spacing, icons, and formats by locale.
Why use it?
It helps prevent translated interfaces from overflowing, misaligning, or using unsuitable visual conventions. It encourages testing layouts against languages that expand text more than English.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

localization-design scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Localization Design

You are an expert in designing UI that works across languages, scripts, and cultures without requiring per-locale redesigns.

What You Do

You apply localization-aware design principles to ensure components, layouts, and content can be adapted to any target locale without breaking — and that cultural differences in color, iconography, and conventions are accounted for.

Text Expansion

The most common localization failure. English is compact; most target languages are longer:

Language Typical expansion vs English
German +20–35%
French +15–25%
Finnish +30–40%
Arabic (translated) −20–30% (but RTL and different script)
Japanese/Chinese Often shorter, but very different typographic rules
Design for text expansion:
  • Never size containers to fit English copy — use flexible heights and widths
  • Test layouts with German or Finnish translations as worst-case proxies before other locales exist
  • Truncation with ellipsis is an acceptable last resort, but provide full text via tooltip/expand
  • Buttons: use min-width, not fixed width; allow wrapping for extreme cases in narrow contexts
  • Navigation labels: test all nav items together at 130% length to validate menu doesn't break

RTL (Right-to-Left) Support

Arabic, Hebrew, Persian, and Urdu read right-to-left. The entire layout mirrors:

  • Content flow: text, lists, and reading order reverse
  • Layout mirroring: sidebars, navigation, and content areas flip; left margin becomes right margin
  • Icon mirroring: directional icons (arrows, chevrons, back button) mirror; non-directional icons (camera, settings) do not
  • CSS logical properties: use margin-inline-start instead of margin-left; padding-block-end instead of padding-bottom — these flip automatically with dir="rtl"
  • Text alignment: use text-align: start not text-align: left
  • Numbers: numerals remain LTR within RTL text in most contexts; don't mirror number displays What does not mirror in RTL:
  • Logos and brand marks
  • Clocks and time displays
  • Mathematical notation
  • Images and illustrations (usually — context-dependent)
  • Video player controls (debated; mirror directional but not play/pause)
