A workflow for adding languages and translation text to an application's internationalisation system. Internationalisation, often shortened to i18n, lets one application show text in multiple languages.

Use it when adding a language, changing translated text, or creating a new translation key.

It keeps translation keys consistent across the application's language files and checks that the compiled translations are complete.

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	$0.00060	$0.00853
Opus 5	$0.00030	$0.00426
Sonnet 5	$0.00012	$0.00171
Haiku 4.5	$0.00006	$0.00085

Security

Grade A, and why

add-locale 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 5d 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.

How it starts

The opening of the file, as written. The whole thing — 32 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Add a locale / translation keys

i18n source files are co-located per feature (app/<Feature>/languages/<locale>.js) plus the global languages/<locale>.js. They compile into locales/<locale>.json via yarn lang — never edit locales/*.json directly. Read README "Global Languages / Locales". For the full deep reference, see docs/core/errors.md.

Plan the locale/key contract, fallback/copy, affected features, and tests and get sign-off before editing. Every affected feature must retain complete standard structure.

Add (or edit) a translation key

Add the key to the relevant languages/en.js (feature-level for feature strings, global languages/en.js for shared). Format: NAMESPACE[snake_case] — NAMESPACE = feature name ALL_CAPS or GLOBAL; key lowercase_with_underscores. Interpolate with {{var}}.
Add the same key to every other locale file that exists (each locale must have the same keys).
Run yarn lang — it compiles locales/ and validates that every static .__('KEY') in the code exists. It throws in test/prod on missing keys (and yarn test runs it first), so always run it after editing.
Use it: req.__('NAMESPACE[key]', { var }) in actions, i18n.__(...) (from getLocalI18n()) in tasks/services.

Add a brand-new locale (e.g. 'es')

Add the locale code to the LOCALES array and LOCALE map in helpers/constants.js (LOCALE keys are UPPER_CASE: { EN: 'en', ES: 'es' }; LOCALES: ['en','es'], first index is the default).
Add the global languages/<locale>.js. For every feature, run yarn repair <Feature> --dry-run, review, then yarn repair <Feature> so the shared generator template creates the missing feature locale without overwriting files.
Fill every generated app/*/languages/<locale>.js with the full mirrored key set, then run yarn lang.

Using translations: actions vs tasks

In an Express action: locale is set automatically (detection order: req.user.locale → lang in req.args → i18n-locale cookie → default en). Never call setLocale manually. Use req.__('NS[key]', { var }) or res.__(...).
In a task/service (no req): get a fresh instance and set the locale yourself — const i18n = lang.getLocalI18n(); i18n.setLocale(job.data.locale || 'en'); then i18n.__('NS[key]'). When enqueuing a job that produces user-facing strings, pass locale: req.user.locale in job.data.
Never require('i18n') directly in a task/service — shared state bleeds across concurrent jobs. Always getLocalI18n().

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.

add-locale is a skill published in the GitHub repository Hackbyrd/orbital-express (14 stars, last pushed 16d ago), licensed MIT. It adds 60 tokens to every session and 853 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
