At a glance

Fills missing translations in claude-tap's viewer_i18n.json by sending untranslated keys to OpenRouter for Japanese, Korean, French, Arabic, German and Russian.

  • Works in 3 steps: Check what's missing (dry run) → Run the translation → Verify the result
  • Adding a new UI string to the claude-tap viewer
  • SKILL.md covers Prerequisites, Workflow, Options and How it works, plus 1 more section
  • Calls uv; needs OPENROUTER_API_KEY

What it does

This skill is for the claude-tap project's viewer strings. After English or Chinese UI text changes in claude_tap/viewer_i18n.json, it finds keys present in both the en and zh-CN blocks but missing from the other languages and translates them through OpenRouter, defaulting to the google/gemini-2.5-flash model. The steps are a dry run first, then the real run that writes back into the JSON file in place, then a JSON syntax check and the project's pytest test.

The script checks that every language block is a string-to-string map, includes existing translations in its prompt for consistency, normalizes fullwidth punctuation for CJK languages to match the zh-CN style and inserts new entries after the existing keys. Flags include --dry-run, --model, --target, --file and --object-name. It only fills missing keys, so changing an existing string means deleting it from the target blocks before rerunning. OPENROUTER_API_KEY must be set in the environment.

When your agent uses it

  • Adding a new UI string to the claude-tap viewer
  • Checking which translation keys are missing with a dry run
  • Re-translating a changed string after removing it from the target languages

Example prompts

  • “I added a new label to viewer_i18n.json, so fill in the other languages.”
  • “Do a dry run of the i18n translation to see which keys are missing.”
  • “Re-translate the changed export button text into every target language.”

Requirements

  • An OPENROUTER_API_KEY environment variable
  • uv and the project's Python environment
  • The repository's scripts/translate_i18n.py script

Workflow steps

3 steps, taken from the step headings in SKILL.md.

  1. Check what's missing (dry run)
  2. Run the translation
  3. Verify the result

What it can do on your machine

Read from SKILL.md and the folder at commit e17ed32. 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:

    • uv

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

  • Network

    No URLs in SKILL.md. Its commands use uv, 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 these keys or tokens, usually read from environment variables:

    • OPENROUTER_API_KEY

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Viewer i18n Translator loads about 666 tokens when it runs. Until then it costs about 58 tokens; SKILL.md has 290 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~58
When it runs · the whole SKILL.md, loaded when a task matches
~666

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.

Translate i18n

Automatically fill missing translations for the viewer's claude_tap/viewer_i18n.json source file. The script uses English and Chinese as source languages and translates to Japanese, Korean, French, Arabic, German, and Russian.

Prerequisites

  • OPENROUTER_API_KEY must be set in the environment (it is in the user's .zshrc)
  • Default model: google/gemini-2.5-flash

Workflow

1. Check what's missing (dry run)

Always preview first to confirm which keys need translation:

bash
uv run python scripts/translate_i18n.py --dry-run

This parses claude_tap/viewer_i18n.json, finds keys present in both en and zh-CN but missing in other languages, and lists them without modifying the file.

2. Run the translation
bash
uv run python scripts/translate_i18n.py

The script calls OpenRouter once per target language, then writes the translations back into viewer_i18n.json in-place.

3. Verify the result

After translation, run the formatter and tests to make sure nothing broke:

bash
uv run python -m json.tool claude_tap/viewer_i18n.json >/dev/null
uv run pytest tests/test_translate_i18n.py -v

Options

FlagPurpose
--dry-runShow missing keys only, no file changes
--model MODELOverride the OpenRouter model (default: google/gemini-2.5-flash)
--target {viewer,cli}Translation target preset (default: viewer)
--file PATHOverride target file path
--object-name NAMEOverride the legacy JS/Python i18n object name

How it works

The script:

  1. Loads the viewer i18n JSON source file
  2. Validates that every language block is a string-to-string map
  3. Identifies keys present in en + zh-CN but missing in target languages
  4. Sends a structured prompt to OpenRouter with existing translations for consistency
  5. Normalizes fullwidth punctuation for CJK languages (matching zh-CN style)
  6. Inserts new entries after the existing keys in each target language

Common scenarios

Added a new UI string: Add the key to both en and zh-CN blocks in claude_tap/viewer_i18n.json, then run this skill. The other 6 languages will be filled automatically.

Changed an existing string: The script only fills missing keys. To re-translate an existing key, first delete it from the target language blocks, then run the script.
