Key Capabilities:

• Complete pipeline orchestration (not component duplication)
• Working hi-res PNG capture script (fixes Playwright CLI limitations)
• Exact CSS templates from paralleLLM empathy v1.0/v2.0
• Full command sequences with copy-paste examples

When to Use This Skill

Trigger Phrases:

• "create a benchmark report"
• "write up my AI experiment"
• "publication-quality benchmark documentation"
• "full report with diagrams and PDF"
• "empathy experiment style report"

Use Cases:

• AI/ML benchmark evaluation reports
• Model comparison studies
• Empirical experiment writeups
• Research documentation with figures

NOT for:

• Single diagram creation (use html-diagram-creator)
• Simple markdown to PDF (use markdown-to-pdf-converter)
• ASCII diagrams (use ascii-diagram-creator)

Quick Start

Prerequisites

# Install all dependencies
brew install pandoc
pip install weasyprint
npm install playwright
npx playwright install chromium

Complete Pipeline (3 commands)

# 1. Create HTML diagram
#    [Use html-diagram-creator skill or copy template]

# 2. Capture diagram to high-res PNG
node scripts/capture-diagram.js diagram.html figures/figure-1.png

# 3. Convert markdown report to PDF
pandoc report.md --standalone --css=templates/pdf-style.css -t html | weasyprint - report.pdf

Pipeline Phases

Phase 1: Document Structure

Use the report-creator pattern or copy from reference/report-template.md:

Phase 2: Create Diagrams

Use the html-diagram-creator pattern for publication-quality HTML diagrams.

Color Palette (Academic Standard):

→ Full templates: reference/html-templates.md

Phase 3: Capture to PNG (CRITICAL)

Important: The Playwright CLI --device-scale-factor flag does NOT exist. Use the provided Node.js script instead:

# Working high-res capture (2x retina quality)
node scripts/capture-diagram.js diagram.html output.png

# The script handles:
# - deviceScaleFactor: 2 (retina quality)
# - .diagram-container selector targeting
# - Proper file:// protocol handling

Why not CLI? Playwright's CLI screenshot command doesn't support --device-scale-factor. The bundled script uses the Playwright API directly.

Phase 4: Embed in Markdown

<figure style="margin: 2em auto; page-break-inside: avoid; text-align: center;">
  <img src="figures/figure-1.png" alt="Description" style="max-width: 100%; height: auto;">
  <figcaption style="text-align: center; font-style: italic; margin-top: 1em;">
    Figure 1: Caption text.
  </figcaption>
</figure>

Phase 5: Export to PDF

# Two-step (for debugging)
pandoc report.md -o report.html --standalone --css=templates/pdf-style.css
weasyprint report.html report.pdf

# One-liner (production)
pandoc report.md --standalone --css=templates/pdf-style.css -t html | weasyprint - report.pdf

CSS Template Standards

The bundled templates/pdf-style.css follows empathy v1.0/v2.0 conventions:

Tables (Academic Style)

• Header: 2px solid top/bottom borders
• Body: 1px solid bottom borders
• Last row: 2px solid bottom border
• page-break-inside: avoid

Figures

• max-width: 100% (NOT min-width)
• margin: 2em auto for centering
• page-break-inside: avoid
• Italic captions centered below

Page Control

• 2cm margins
• Headings: page-break-after: avoid
• Orphans/widows: 3 lines minimum

Troubleshooting

Success Checklist

• All prerequisites installed (pandoc, weasyprint, playwright)
• Diagram HTML created with academic styling
• PNG captured at 2x resolution using script (not CLI)
• Markdown has proper figure tags with captions
• PDF renders without errors
• Tables don't split across pages
• Figures centered with captions
