What it does
PDF Translate is an agent skill from breslee1707/VI-Translate. Translate local PDFs, including safe prose on image-only scans, into Vietnamese or another supported Latin-script language while preserving layout, formulas, tables, and figures. Use for PDF translation, OCR-assisted scan translation, batch translation, terminology-sensitive handoff translation, or diagnosing incomplete output. Do not use for targets requiring CJK, right-to-left, or complex-script shaping.
Its SKILL.md is about 2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 234 other files, including scripts and reference files (for example `.github/workflows/android-build.yml`, `.github/workflows/macos-artifacts.yml` and `.github/workflows/release.yml`).
It sits in Documents & Office, covering Translation and PDF. The licence is AGPL-3.0-only.
When your agent uses it
- PDF translation
- OCR-assisted scan translation
- Batch translation
- Terminology-sensitive handoff translation
Example prompts
- “/pdf-translate”
Requirements
- Python 3
Workflow steps
3 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 302a6da. 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
Ships 1 file in scripts/, which the agent can run.
Shell commands in SKILL.md call:
pythonpython3
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
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
PDF Translate loads about 2k tokens when it runs, and up to ~3.9k if it reads all its reference files. Until then it costs about 106 tokens; SKILL.md has 938 words of instructions outside code blocks.
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); the scripts in this folder are not scanned.

PDF Translate
Translate a PDF with the bundled Code4Life engine. Keep the source file unchanged and produce a separate PDF with the same page structure.
When this skill runs inside the repository, first read
agent-knowledge/index.md. For preservation or
layout work, load its PDF engine, regression, and validation routes. These are
the shared project instructions for Codex and Claude; do not duplicate them in
this entrypoint.
Resolve the skill root
This skill may be installed globally while the user's files live elsewhere. Resolve the absolute directory containing this SKILL.md before running anything. Call its scripts and dependency files by absolute path; do not assume the current working directory is the skill directory.
Use the interpreter inside <skill-root>/.venv:
- Windows:
<skill-root>\.venv\Scripts\python.exe - macOS/Linux:
<skill-root>/.venv/bin/python
Choose a mode
| Mode | Translator | Use when |
|---|---|---|
| Google (default) | translate.google.com | Books, batches, first drafts, or low token use |
| Handoff | The active agent | Terminology, context, or translation quality matters |
Default to Google. Offer handoff when the user asks for higher quality, rejects the Google result, or provides a short technical document.
Boundaries
- Use the bundled
pdf2zh/core. Never substitute the PyPIpdf2zhpackage; the runner checks version1.9.11and preservation rulesetcode4life-preservation-v1and refuses an external core. - Google mode sends extracted document text to Google. Tell the user before processing sensitive material and obtain explicit confirmation unless their request already authorizes that disclosure. Handoff mode does not contact Google.
- Supported targets are the Latin-script codes enforced by
scripts/translate_pdf.py. CJK, right-to-left, Thai, Devanagari, and other complex-shaping targets are rejected because the bundled font and layout engine cannot render them reliably. - OCR is opt-in with
--ocr standard|enhanced. It fails closed on unsafe tables, formulas, figures, code and ambiguous reading order; report every preserved region as partial instead of claiming the whole scan was translated. - Text inside detected tables, figures, contents pages, indexes, symbol lists, or references may intentionally remain in the source language. Report material untranslated regions as partial translation.
- Preserve the source. Write results to a separate output directory. Do not pass
--overwritewithout explicit replacement authorization.
Read the preservation contract before changing layout behavior, diagnosing preserved pages, or investigating untranslated regions.
Set up the runtime
Use Python 3.11 or 3.12. Create <skill-root>/.venv and install <skill-root>/requirements.txt if the environment is absent or stale. Keep this environment separate from the user's project.
The source distribution downloads layout and font assets on its first translation, so the first run needs network access and takes longer. The packaged Windows app already contains these assets.
Windows:
python -m venv "<skill-root>\.venv"
& "<skill-root>\.venv\Scripts\python.exe" -m pip install -r "<skill-root>\requirements.txt"macOS/Linux:
python3 -m venv "<skill-root>/.venv"
"<skill-root>/.venv/bin/python" -m pip install -r "<skill-root>/requirements.txt"Shared runner options include --target-language (default vi), --source-language auto, one-based --pages 1,3-5, --threads 1..8 (default 4; Google mode still sends one request at a time), --ignore-cache, and --overwrite.
Google mode
Run one command per file. Use absolute paths for the input and output directory.
Windows:
& "<skill-root>\.venv\Scripts\python.exe" "<skill-root>\scripts\translate_pdf.py" "<input.pdf>" --output-dir "<output-dir>"macOS/Linux:
"<skill-root>/.venv/bin/python" "<skill-root>/scripts/translate_pdf.py" "<input.pdf>" --output-dir "<output-dir>"For a batch, process files individually and report progress. A file-specific failure must not stop the remaining files. A Google block or exhausted service outage pauses the whole queue; successful translations remain cached for a later retry, and no incomplete PDF is published for that interrupted file.
Google mode sends a page's segments in one request, one request at a time, because the free endpoint blocks a network that floods it. Never run several Google jobs in parallel.
If a run encounters HTTP 429 or a CAPTCHA, the runner stops the document and pauses the queue. For the next 10 minutes it refuses further Google runs before OCR/model work. This is the app's cooldown, not a prediction of Google's recovery time. Do not rerun it in a loop or try to get past the CAPTCHA. Report it, then offer a later rerun (finished segments are cached) or handoff mode.

Handoff mode
Handoff extracts translatable segments to JSONL, lets the active agent translate them, then rebuilds the PDF. Warn about token and time cost before starting a large document. For long documents, suggest a representative sample such as --pages 1-5 first.
1. Extract
An output directory is not required during extraction because the pass-one PDF is discarded.
<python> <skill-root>/scripts/translate_pdf.py <input.pdf> --engine handoff --emit-segments <segments.jsonl>2. Translate
Read segments.jsonl in manageable batches. Write one JSON object per line to translations.jsonl:
{"src":"exact source text","dst":"translated text"}Copy each src value exactly. Preserve URLs, paths, identifiers, citation markers, and numbers.
Formula and code placeholders such as <b0></b0> are immutable. Every opening and closing tag must retain the same identifier, count, and order as the source. The loader rejects a record whose placeholders differ, leaving that segment untranslated.
Inline emphasis markers are immutable as balanced pairs: <s1>...</s1> is
bold, <s2>...</s2> is italic, and <s3>...</s3> is bold italic. Complete
style pairs may move with the translated phrase, but none may be dropped,
duplicated, or cross-nested. Invalid style markup leaves the segment
untranslated instead of silently losing emphasis.
3. Rebuild
<python> <skill-root>/scripts/translate_pdf.py <input.pdf> --engine handoff --segments <translations.jsonl> --output-dir <output-dir> --emit-segments <still-missing.jsonl>The command prints the remaining untranslated segment count. If it is nonzero, translate still-missing.jsonl, append valid records to translations.jsonl, and rebuild again. Stop only at zero or when a segment cannot be translated safely; then report the exact remaining limitation.
Extraction and rebuild each run the layout pass, so handoff uses roughly twice the local PDF processing of Google mode in addition to the agent's translation work.
Verify before delivery
- Confirm the output exists and the source still exists unchanged.
- Confirm source and output page counts match.
- Extract text page by page and check for substantial untranslated passages, missing formulas, damaged URLs, or lost identifiers.
- When page rendering or image inspection is available, render every output page and inspect for blank pages, missing glyphs, clipping, overlap, and displaced tables or figures.
- If full visual inspection is unavailable, say which checks were completed. Do not present a partially verified or partially translated file as fully complete.
