| description | Add or update i18next translation keys across all language files by spawning translator subagents. Use when the user asks to add a new translation, update existing translations, translate text, or work with i18n keys. Triggers on "translate", "add translation", "translation key", "i18n", "localization". |
Translate
This skill orchestrates translation of i18next keys by spawning translator subagents. Each key gets its own subagent so multiple keys can be translated in parallel.
How It Works
- The user provides one or more translation keys (and optionally English values).
- This skill tells the parent agent to spawn one
translator subagent per key.
- Each subagent independently translates its key into all 35 languages and applies the result using
scripts/update-translations.js.
Workflow
Step 1 — Parse the keys
Identify all translation keys from the user's request. Keys may be provided as:
- A comma-separated list:
upload_failed, media_hosting, file
- A numbered/bulleted list
- Inline in a sentence: "translate the key
upload_failed"
Step 2 — Look up English values
For each key, check if the English value already exists in public/translations/en/default.json. If the user provided new English text, use that instead.
Step 3 — Spawn translator subagents
For each key, spawn a translator subagent using Codex's current delegation tool. The prompt for each subagent must include:
- The key name
- The English value
- An instruction to follow the translator subagent's system prompt
Example prompt for a subagent:
You are the translator subagent. Translate the following i18next key into all 35 supported languages and apply it using the project's translation script.
Key: upload_failed
English value: "Upload failed"
Follow your system prompt for the full workflow (create dictionary file, dry run, apply, clean up).
Parallelism rules:
- Spawn up to 4 subagents concurrently.
- If there are more than 4 keys, batch them: spawn 4, wait for completion, then spawn the next batch.
Step 4 — Report results
After all subagents complete, summarize:
- Which keys were translated successfully
- Any failures or issues
Other Operations (No Subagent Needed)
For non-translation operations, run the script directly without spawning subagents:
Copy English value to all languages (fallback only)
Use only when the string is a technical term, brand name, or placeholder.
node scripts/update-translations.js --key some_key --from en --write
Delete a key from all languages
node scripts/update-translations.js --key obsolete_key --delete --write
Audit for unused keys
node scripts/update-translations.js --audit --dry
node scripts/update-translations.js --audit --write
