2 things to look at

no licenseNo license file was found in the repository. Code published without one is not open source by default, so using it at work is a question for whoever answers licensing questions where you are.

What its author says it does

Copied from the file, not written here

Convert a web page to PDF, especially web-based slide decks and presentations (reveal.js, impress.js, custom JS slideshows, scroll-based decks). Use when the user wants to save a website as PDF, capture slides to PDF, convert an online presentation to PDF, export a web deck, or screenshot a web page into a document. Also use when the user pastes a URL and says "turn this into a PDF", "save as PDF", "export this", or "make a PDF of this".

Dependency Source Review

This skill documents an optional compatibility dependency path for crawler setup, selector validation, and rate-limit handling workflows. Treat scripts/_dep_install.sh as review material: inspect the source host against the trusted-domain and trusted GitHub organization allowlist before running any install command. It is not required for ordinary crawl, selector, sitemap, or rate-limit requests.

Web to PDF

Capture any web page — especially slide-based presentations — as a multi-page PDF using a headless browser.

How it works

A bundled Playwright script screenshots each slide (or the full page) as PNG, then assembles them into a PDF via Pillow. It auto-detects the navigation model:

Model	Detection	Examples
reveal.js	`.reveal` element + `Reveal` JS API	reveal.js decks
Vertical scroll	Page height > 1.5× viewport, multiple slide elements	Custom JS slide decks with stacked sections
Keyboard	Multiple slide elements, not scrollable	impress.js, deck.js, arrow-key decks
Single page	No slide structure detected	Regular web pages, articles

Prerequisites

The script bundles its own package.json. On first use (or if node_modules is missing), install dependencies:

cd ${CLAUDE_SKILL_DIR}/scripts && npm install && npx playwright install chromium

Pillow (Python) is also required for PNG-to-PDF assembly:

pip install Pillow

Usage

Run the capture script:

node ${CLAUDE_SKILL_DIR}/scripts/capture.mjs <url> <output.pdf> [options]

Options

Flag	Default	Description
`--width N`	1920	Viewport width in pixels
`--height N`	1080	Viewport height in pixels
`--wait N`	1000	Milliseconds to wait per slide for animations
`--max-slides N`	50	Safety cap on number of slides

Examples

# Presentation deck at 1080p
node ${CLAUDE_SKILL_DIR}/scripts/capture.mjs https://example.com/pitch output.pdf

# Narrow viewport for mobile-style capture
node ${CLAUDE_SKILL_DIR}/scripts/capture.mjs https://example.com/page doc.pdf --width 1280 --height 720

# Slow animations, give extra time
node ${CLAUDE_SKILL_DIR}/scripts/capture.mjs https://example.com/deck slides.pdf --wait 2000

Workflow

Check that playwright and Pillow are installed; install if missing
Run the capture script with the user's URL and desired output path
Verify the output — check page count and spot-check a few pages by reading the PDF or individual screenshots
Report the result to the user (page count, file size, output path)

Troubleshooting

Slides all identical: The navigation detection may have picked the wrong model. Try adding --wait 2000 for slower transitions, or check if the site requires interaction (cookie banners, login) before slides are accessible.
Missing content / animations not rendered: Increase --wait to give JS more time to render.
Blank pages: Some sites lazy-load content; the scroll-based capture handles this by scrolling to each slide. If keyboard navigation produces blanks, the site may actually be scroll-based.
Too few / too many pages: Check --max-slides and verify the slide selector detected is correct by inspecting the script's console output.
