translation diff translate

Use this skill after translation-diff-export produced a .source.json, .translated.json, and .reference.json set and you want to update the sparse translated working copy.

It translates only the active patch keys, keeps .translated.json as the sole writable file, preserves placeholders and formatting, and hands the completed working copy to translation-diff-import for merge-back.

Execution Expectations

1. Edit .translated.json directly. Do not create helper scripts, temporary reports, or coverage probes.
2. Do not install packages or search for external translation services unless the user explicitly asks for automation.
3. If .translated.json is empty, that is expected. Translate from .source.json into .translated.json.
4. Use .reference.json only as terminology guidance, not as a reason to pause and analyze the rest of the repository.
5. If the patch is too large to finish reasonably in one pass, report that constraint to the user instead of creating automation on your own.

Script

• scripts/write-translation-handoff.ps1: Writes a small .prompt.md file that points an agent at this skill with the concrete patch paths created by the export skill.

Usage

Generate a handoff prompt for a translated French working copy:

pwsh ./.agents/skills/translation-diff-translate/scripts/write-translation-handoff.ps1 \
  -BaseName lang \
  -Language fr \
  -SourcePatch ./generated/translation-diff-export/lang.diff.fr.source.json \
  -TranslatedPatch ./generated/translation-diff-export/lang.diff.fr.translated.json \
  -ReferencePatch ./generated/translation-diff-export/lang.diff.fr.reference.json \
  -TargetJson ./src/Languages/lang_fr.json \
  -NeutralJson ./src/Languages/lang_en.json \
  -MergedTargetJson ./src/Languages/lang_fr.merged.json \
  -ValidationScript ./.agents/skills/translation-diff-import/scripts/validate-language-file.ps1 \
  -OutputPrompt ./generated/translation-diff-export/lang.diff.fr.prompt.md

Translation Rules

1. Do not edit .source.json.
2. Write completed translations only into .translated.json.
3. If a key is not translated yet, omit it from .translated.json instead of copying the English source value.
4. Preserve key names exactly as-is.
5. Preserve placeholders, named tokens, HTML-like fragments, escape sequences, and line breaks.
6. Keep translated entries in the same key order as .source.json when adding new entries.
7. Use .reference.json to match existing terminology and tone in the destination language.
8. Do not introduce keys that are not present in the source patch.

After Translation

Merge the sparse working copy back into the full destination-language file:

pwsh ./.agents/skills/translation-diff-import/scripts/import-translation-diff.ps1 \
  -TranslatedPatch ./generated/translation-diff-export/lang.diff.fr.translated.json \
  -SourcePatch ./generated/translation-diff-export/lang.diff.fr.source.json \
  -TargetJson ./src/Languages/lang_fr.json \
  -NeutralJson ./src/Languages/lang_en.json \
  -OutputJson ./src/Languages/lang_fr.merged.json

pwsh ./.agents/skills/translation-diff-import/scripts/validate-language-file.ps1 \
  -NeutralJson ./src/Languages/lang_en.json \
  -TargetJson ./src/Languages/lang_fr.merged.json \
  -PatchJson ./generated/translation-diff-export/lang.diff.fr.source.json
