| description | PDF parsing (uv + pdfplumber / pypdf): use this for reading or extracting text/tables from any PDF.

Hard rule: never use PyMuPDF / fitz (AGPL). |
office-pdf — generate and parse PDF
Two independent paths: generate a PDF from HTML using PawWork's bundled Chromium, and parse an existing PDF with permissively-licensed Python libraries.
License hard rule (non-negotiable)
Never use PyMuPDF / fitz / pymupdf — it is AGPL and must not enter the product. Also avoid any tool that shells out to it. Allowed parsers are pdfplumber (MIT) and pypdf (BSD) only. For rendering, use the bundled Chromium — not wkhtmltopdf, not LibreOffice, not a system-installed browser.
Runtime contract
uv must be on PATH for the parse path. Parsing runs through uv run; the runtime injects the package-mirror environment variables so uv resolves pdfplumber / pypdf from the internal mirror. You do not configure the mirror.- If
uv is missing (parse path), stop and report exactly: office-pdf parsing requires 'uv' on PATH, but 'uv --version' failed. This is an environment problem — uv should be provisioned by the PawWork runtime. Do not fall back to system pip; report the missing uv instead.
- The skill directory ships read-only inside the app bundle. Never write into it. Work in a fresh directory.
Path 1 — Generate (HTML → Chromium printToPDF)
PawWork bundles its own Chromium; the PDF is produced by that engine's Page.printToPDF (Chrome DevTools Protocol) driving your HTML. No external browser install, no wkhtmltopdf, no LibreOffice.
Author a self-contained HTML file built for print:
- Set page geometry with
@page { size: A4; margin: 18mm; } (or Letter, or an explicit size: 210mm 297mm).
- Inline all CSS and, where practical, images (as
data: URIs) so the page renders without network fetches.
- Use
page-break-before/after / break-inside: avoid to control pagination; design against print CSS, not screen scroll.
- Prefer real text and CSS/SVG vector graphics over rasterized screenshots so the PDF stays selectable and crisp.
Then render it to PDF through the runtime's bundled-Chromium print entry point (Page.printToPDF over the browser bridge). If the current build exposes no PDF/print tool, report that the generation path is not available in this runtime rather than shelling out to an unbundled browser or an AGPL library — this can happen while the bundled-Chromium print entry point is still being wired up, so degrade gracefully instead of substituting another tool.
Path 2 — Parse (uv + pdfplumber / pypdf)
SKILL_DIR is the skill's base directory as a plain filesystem path — copy the line labeled "Base directory as a plain filesystem path" from the skill-load output. Do not use the file:// URL form; if only a file:// URL is available, strip the file:// prefix first.
SKILL_DIR="<plain filesystem path from the skill-load output, no file:// prefix>"
uv --version >/dev/null 2>&1 || { echo "office-pdf parsing requires 'uv' on PATH, but 'uv --version' failed. This is an environment problem — uv should be provisioned by the PawWork runtime. Do not fall back to system pip; report the missing uv instead."; exit 1; }
mkdir -p work && cp "$SKILL_DIR/pyproject.toml" work/pyproject.toml
The shipped pyproject.toml pins both parsers so either import resolves offline, but you only need one per task — choose by need, both run from work/:
pdfplumber — layout-aware text and table extraction; use when you need columns, tables, or word positions.
uv run python -c "import pdfplumber,sys; \
[print(p.extract_text() or '') for p in pdfplumber.open(sys.argv[1]).pages]" input.pdf
pypdf — fast plain-text, metadata, page count, and split/merge; use for quick text or manipulation.
uv run python -c "from pypdf import PdfReader; import sys; r=PdfReader(sys.argv[1]); \
print(len(r.pages), 'pages'); print(r.pages[0].extract_text())" input.pdf
If text extraction returns empty, the PDF is likely scanned images — say so and stop; do not reach for PyMuPDF or any AGPL OCR-render path.
