Internationalization and translation management. An agent skill from Sidiora-Labs/centra-llm-agents.

  • Works in 4 steps: Design provides translation key like… → Run sync command: yarn fetch:locale → Convert key format:… → …
  • Adding translations
  • SKILL.md covers Critical Restrictions, Quick Reference, Translation Workflow and Translation Key Naming Pattern, plus 3 more sections
  • Calls yarn

What it does

I18n is an agent skill from Sidiora-Labs/centra-llm-agents. Internationalization and translation management. Use when adding translations, displaying text, handling locales, or managing translation keys. NEVER modify auto-generated translation files. Triggers on i18n, translation, locale, formatMessage, useIntl, ETranslations, text, string, hardcode, intl, translate, language, localization, internationalization.

Its SKILL.md is about 760 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `references/rules/i18n.md`).

It sits in Frontend & Design, covering Internationalization and Translation. The repository describes itself as: A stateful AI operating system for serious, long-horizon work.

When your agent uses it

  • Adding translations
  • Displaying text
  • Handling locales
  • Managing translation keys

Example prompts

  • “/i18n”

Requirements

  • Pre-approved tools (allowed-tools): Read, Grep, Glob

Workflow steps

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

  1. Design provides translation key like prime::restore_purchases
  2. Run sync command: yarn fetch:locale
  3. Convert key format: prime::restore_purchases → ETranslations.prime_restore_purchases
  4. Use in code

What it can do on your machine

Read from SKILL.md and the folder at commit 01c6aef. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Grep
    • Glob

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • yarn

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

  • Network

    No URLs in SKILL.md. Its commands use yarn, 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 760 tokens when it runs, and up to ~1.6k if it reads all its reference files. Until then it costs about 90 tokens; SKILL.md has 136 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~90
When it runs · the whole SKILL.md, loaded when a task matches
~760
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.6k

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.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 136 words (~760 tokens).
