What is i18n-locale-parity-review?

A review skill for multilingual websites and applications. It checks that translations have matching keys, that internationalisation setup is complete, that language links support search engines, and that content fits local cultures.

Use it to review locale parity, missing translation keys, internationalisation setup, hreflang, multilingual SEO, and cultural adaptation.

It helps find missing or inconsistent translations and problems that make different language versions behave differently. It also covers hreflang, a signal that tells search engines about language and regional page versions.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00032	$0.03010
Opus 5.5	$0.00013	$0.01204
Sonnet 5.5	$0.00006	$0.00602
Haiku 4.5	$0.00003	$0.00301

Security

Grade A, and why

i18n-locale-parity-review 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 27d ago.

The scan reads SKILL.md. This mod also ships 5 executable files (references/i18n-agent/tests/test_check_i18n_seo.py, scripts/i18n-agent/check_i18n_seo.py, scripts/i18n-agent/extract_translatables.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

The source is not reproduced here

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

Files

What ships with it

60 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
