pdf-html — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited pdf-html (Agent Skill) and scored it 91/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

First recorded scan — no prior version to compare against.
The primary manifest — the file an agent reads to learn what this artifact does.
Targeted per-canvas PDF export via headless Chromium. Strips preview-backdrop styles (dark page background, padding, gap) before rendering so the PDF contains only the canvas itself.
design-* skill that produces a document-style HTML artifact — audit reports,deliverables, spec sheets, long-form cards — and a PDF is the desired leave-behind format.
Skip if:
card). Use screenshot-html for those — PDFs don't add value and print media mode may alter the styling.
screenshot-html.Same canvas conventions as screenshot-html:
.canvas — primary fixed-size artifact wrapper.[class*="canvas-"] — modifier variants: canvas-front / canvas-back, canvas-audit,canvas-og / canvas-hero, etc.
.scene — hash-routed scenes (captured at their hash-navigated state).Nested matches are deduped — only top-level containers generate PDFs.
If a file has no matches, falls back to a full-page PDF. --full-page forces this for every file.
node skills/pdf-html/scripts/pdf-html.mjs <dir> [--output <dir>] [--width <px>] [--full-page]Flags:
<dir> (positional, default .): directory to scan recursively for *.html. Thescreenshots/ and pdfs/ subdirectories and hidden dirs are skipped.
--output <dir> (default <dir>/pdfs): where PDFs are written. Flat output — one fileper canvas target.
--width <px> (default 1920): browser viewport width. Only needs to be ≥ the widestcanvas; PDF height is measured from the rendered DOM, not the viewport.
--full-page: force full-page PDFs for every file, skipping canvas targeting.Height is always auto-measured from the canvas's rendered bounding box — no --height flag needed.
None — the script self-bootstraps on first run, installing Playwright and the Chromium binary into its own node_modules alongside the script. First run takes ~10–60s; subsequent runs are fast (~1s overhead).
$ node pdf-html.mjs ./design/<brand>/artifacts
Playwright not found. Installing into <skill-dir>/scripts/node_modules (one-time)…
…Same @import sanity check as screenshot-html: if a relative @import url('../tokens.css') can't resolve from the artifact's directory, the guard warns you before writing the PDF:
artifact.html ⚠ design tokens may not have loaded — PDF may show fallback styles.
failed CSS: file:///wrong/path/tokens.css (net::ERR_FILE_NOT_FOUND)
Fix: run the script against the artifact's native folder so relative imports resolve.Playwright's page.pdf() renders in @media print mode. For design-* artifacts the canvas CSS contains no @media print overrides, so the rendered PDF matches the browser preview. The preview-backdrop styles (body { background: #2a2a2a; padding: 32px; } and .canvas-label) are stripped via injected CSS before each PDF is generated, so the output contains only the canvas.
PDF dimensions are set to the canvas's exact rendered pixel size (e.g. 1200 × 5077 px for a tall audit report). This produces a single-page vector PDF — shareable, searchable, and printable — at the canvas's native resolution.
Same convention as screenshot-html but with .pdf extension:

|---|---|---|
audit-report-2026-05-14-mercer-advisors.html | one .canvas-audit | audit-report-2026-05-14-mercer-advisors.pdf |
business-card.html | .canvas-front, .canvas-back | business-card--canvas-front.pdf, business-card--canvas-back.pdf |
