Export existing Marp markdown files to PDF (default), HTML, PPTX, or PNG.
bash# PDF (default) — requires Chrome/Chromium npx @marp-team/marp-cli INPUT.md -o OUTPUT.pdf --theme-set ~/.claude/skills/marp-slides-creator/themes/ --allow-local-files --html # HTML npx @marp-team/marp-cli INPUT.md -o OUTPUT.html --theme-set ~/.claude/skills/marp-slides-creator/themes/ --html # PPTX (editable, requires LibreOffice) npx @marp-team/marp-cli INPUT.md -o OUTPUT.pptx --pptx-editable --theme-set ~/.claude/skills/marp-slides-creator/themes/ --allow-local-files # PNG sequence npx @marp-team/marp-cli INPUT.md --images png -o OUTPUT_DIR/ --theme-set ~/.claude/skills/marp-slides-creator/themes/
Find the Marp markdown file. It must contain marp: true in YAML frontmatter.
bash# Verify it's a Marp file head -5 INPUT.md # should show "marp: true"
Themes are stored in the marp-slides-creator skill:
THEME_DIR="$HOME/.claude/skills/marp-slides-creator/themes/"Always use --theme-set "$THEME_DIR/" in all export commands.
PDF and PPTX export require a Chrome/Chromium browser. Marp-cli auto-detects, but if it fails:
bash# macOS Chrome paths (check in order) /Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --version /Applications/Chromium.app/Contents/MacOS/Chromium --version /Applications/Microsoft\ Edge.app/Contents/MacOS/Microsoft\ Edge --version # Set CHROME_PATH if auto-detection fails export CHROME_PATH="/Applications/Google Chrome.app/Contents/MacOS/Google Chrome"
If no browser found, fall back to HTML export and inform the user.
Default format is PDF. User can specify otherwise.
Output naming convention:
presentation.md → presentation.pdfPDF export:
bashnpx @marp-team/marp-cli INPUT.md \ -o OUTPUT.pdf \ --theme-set ~/.claude/skills/marp-slides-creator/themes/ \ --allow-local-files \ --html
HTML export:
bashnpx @marp-team/marp-cli INPUT.md \ -o OUTPUT.html \ --theme-set ~/.claude/skills/marp-slides-creator/themes/ \ --html
Both PDF + HTML:
bash# Run sequentially npx @marp-team/marp-cli INPUT.md -o OUTPUT.pdf --theme-set ~/.claude/skills/marp-slides-creator/themes/ --allow-local-files --html npx @marp-team/marp-cli INPUT.md -o OUTPUT.html --theme-set ~/.claude/skills/marp-slides-creator/themes/ --html
bash# Check output exists and show file size ls -lh OUTPUT.pdf OUTPUT.html 2>/dev/null

DecimalAI ran this skill against gemini-3.6-flash twice over the same eval suite — once with the skill loaded and once without — and compared the two runs case by case. 22 cases were attempted, and 20 counted toward the lift figure. The other 2 produced results that are not comparable between the two arms, so they are excluded from the headline rather than averaged into it. The headline lift of +32 percentage points is the difference between those two pass rates over the 20 comparable cases. 2 cases got worse with the skill loaded, and they are included in that figure.
Without the skill loaded, the model failed this case. With it loaded, the same prompt on the same model passed. This is one improved case from the latest verified run; every case, including any that regressed, is in the table above.
Other measured skills in the registry, with their headline benchmark lift.
