i18n-parity

i18n-parity is a skill for Claude Code, Codex from hoangsonww/Claude-Code-Agent-Monitor. It costs 138 tokens per session (3,408 once invoked), scanned A, original, MIT.

A workflow for keeping translated product text and related language files aligned across five localization surfaces. It treats English as the source and checks that every supported language receives each change.

In plain words
What is it for?
Use it when changing dashboard labels, wiki pages, mirrored README files, locale-aware formatting, or language switchers. It also provides an audit script to check parity.
Why use it?
It prevents parts of a product from being translated while other parts silently fall back to English. This helps contributors avoid missing a language when changing localized content.

Skill for Claude CodeCodex

Written for Claude Code and Codex: PreToolUse hook event, but also agents/openai.yaml present. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions subagents.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is bash .claude/skills/i18n-parity/scripts/sync-agent-mirrors.sh.

Good fit Use it when changing dashboard labels, wiki pages, mirrored README files, locale-aware formatting, or language switchers. It also provides an audit script to check parity.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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

i18n-parity 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 6d 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.

i18n Parity

This repository is localized on five independent surfaces, each with its own mechanism. A change that lands on one and not the others leaves the product half-translated: the English falls through, and the gap is invisible to anyone working in English. This skill states the invariant, maps every surface to the exact files, and gives one command that proves parity.

The invariant: English is the source of truth on every surface, and no change is done until every supported language carries it in the same PR. A fallback to English is a safety net, never a completed translation.

Supported languages are declared in one place — supportedLngs in client/src/i18n/index.ts. Today: en, zh, vi, ko, es. Everything below derives from that list; the audit script reads it rather than hard-coding.

The five surfaces

# Surface English source of truth Translations live in Automated gate
1 Dashboard UI client/src/i18n/locales/en/*.json client/src/i18n/locales/<xx>/*.json (same 15 namespaces) client/src/i18n/__tests__/i18n.test.ts — key, type, and interpolation-token parity
2 Wiki page English text in the wiki/index.html DOM wiki/script.js (T, ATTRIBUTE_TRANSLATIONS, META, languageLabels, the two language ladders) + wiki/i18n-content.js (window.__WIKI_CONTENT_I18N, both the body bundles and plain) client/tests/wiki-i18n.test.ts — live-DOM prose coverage, inline-tag preservation, block-length budgets, asset-version sync
3 Mirrored READMEs README.md README-CN.md (zh), README-VN.md (vi), README-KO.md (ko), README-ES.md (es) partial — scripts/i18n-audit.sh (existence, heading count, cross-links) and server/__tests__/plugins-marketplace.test.js (documented counts); prose parity is review-only
4 Language switchers client/src/components/Sidebar.tsx, client/src/lib/paletteCommands.ts, the two .lang-select-menu blocks in wiki/index.html, nav.json languageNames / languageShort scripts/i18n-audit.sh

What ships with it

3 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.
