markdown-exporter

Plan a deck and generate Reveal.js HTML with tailored themes, multi-column layouts, callouts, charts, speaker notes, animations, and custom CSS. The workflow checks for slide overflow and reviews screenshots, while a browser editor lets you revise text without touching the markup. Presentations open without a build step; overflow checks and PDF export require the included Node dependencies.

Use this Codex skill after a single-slide reference image has established the visual direction. It crops complex illustrations, icons, or maps that are impractical to redraw, while recreating titles, body text, cards, arrows, labels, and conclusion bars with editable PowerPoint objects. The workflow works page by page from individual PNG references and explicitly avoids placing the whole screenshot as a flat slide background, preserving editability where it matters.

SnapDeck drives a running web app with headless Chrome, captures real UI states, reads element coordinates, and renders HTML/CSS slide designs to PNG before assembling a full-bleed .pptx. It can reuse a logged-in session, open tabs or modals, force light mode, and place numbered callouts beside the right controls. The resulting slides are crisp picture slides for demos or training, not editable PowerPoint text and shapes.

The skill turns DOCX files into normalized Markdown by accepting inserted revisions, dropping deletions and comments, repairing heading levels, cleaning tables, replacing broken image references with readable placeholders, and collapsing excess whitespace. A small cross-platform Go binary coordinates Pandoc, so no Python, Node, or Ruby runtime is required. The converter and Pandoc are downloaded lazily on first use and then cached inside the plugin directory.
