What it does

I18n is an agent skill from openathleteorg/openathlete. Add or change user-facing text in OpenAthlete (web app Paraglide catalogs, API emails and push notifications, website) in every supported language. Use for any new or modified UI string, email or notification.

Its SKILL.md is about 510 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. It works with pnpm. The repository describes itself as: The open-source alternative to TrainingPeaks. Self-hostable endurance training platform. Your data stays yours. The licence is AGPL-3.0.

When your agent uses it

  • Modified UI string
  • Tasks that involve Internationalization

Example prompts

  • “/i18n”

Workflow steps

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

  1. Add the key to all four catalogs in apps/web/messages/{en,fr,it,es}.json
  2. Use it as m.full_import_started({ provider }), with import { m } from '@/paraglide/messages'.
  3. Check
  4. Write real translations, not copies of the English. Keep the product terms consistent with the existing catalogs (search them first)…

What it can do on your machine

Read from SKILL.md and the folder at commit a3433f0. 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

    Shell commands in SKILL.md call:

    • pnpm

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

  • Network

    No URLs in SKILL.md. Its commands use pnpm, which can reach the network depending on how they are called.

    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 loads about 512 tokens when it runs. Until then it costs about 54 tokens; SKILL.md has 200 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~54
When it runs · the whole SKILL.md, loaded when a task matches
~512

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.

description
Add or change user-facing text in OpenAthlete (web app Paraglide catalogs, API emails and push notifications, website) in every supported language. Use for any new or modified UI string, email or notification.

User-facing text

Supported languages: English (en), French (fr), Italian (it), Spanish (es). French users use the informal "tu" in AI-generated text and the formal "vous" in the UI, as the existing catalogs do.

Web app

  1. Add the key to all four catalogs in apps/web/messages/{en,fr,it,es}.json:
    • use snake_case, prefixed by the feature (full_import_started, calendar_day_events_label);
    • write parameters as {name};
    • add it next to related keys, not only at the end, to limit merge conflicts.
  2. Use it as m.full_import_started({ provider }), with import { m } from '@/paraglide/messages'.
  3. Check:
    bash
    pnpm check:locale-parity       # same keys in every catalog
pnpm web exec paraglide-js compile --project ./project.inlang --outdir ./src/paraglide
    pnpm find:untranslated lists keys still in English in other catalogs. pnpm find:unused-translations finds dead keys.
  4. Write real translations, not copies of the English. Keep the product terms consistent with the existing catalogs (search them first): training load, CTL/ATL/TSB, the names of sports.

API emails and push notifications

  • Email templates in apps/api/src/modules/notification/emails/templates/ have a translations object with FR, EN, IT and ES. Subjects are in libs/shared/src/email/email.ts.
  • Push texts: apps/api/src/modules/notification/push/translations.ts.
  • The user's language is user.language (UserLanguage enum). Adding a language means a Prisma enum migration (prisma-migration skill).

Website

apps/website/messages/{en,fr}.json, compiled by pnpm website translate.

Verify

scripts/verify.sh runs the parity check and compiles the catalogs. The E2E test renders the dashboard in <locale> checks each locale renders.
