codeck Export (PDF/PPTX)

The codeck publisher lane that exports assembled HTML decks to PDF or PPTX and runs a mandatory visual QA loop.

Docs & OfficeIntermediate★ 198⑂ 19AI score 8/10Last updated: Aug 8, 2026

What it does

  • Locates the assembled deck HTML (*-r*.html) and exports it to PDF or PPTX.
  • PDF is printed WYSIWYG via Playwright/Chromium with screen media emulation and CSS page sizes; PPTX prefers a LibreOffice (soffice) conversion, falling back to per-page screenshots embedded with PptxGenJS.
  • Runs required post-export QA: thumbnails, pdftoppm image dumps, and a subagent visual review looking for overlapping elements, text overflow, uneven spacing, low-contrast text, and drift from the HTML original — with at least one fix-and-verify cycle.
  • Respects write boundaries: never edits deck.md, DESIGN.md, custom.css, slides.html, or speech.md; source defects become threads for the design/review lanes.

Who it's for

  • Users already running the codeck deck-building plugin.
  • Anyone who needs an HTML deck turned into a shareable PDF or an org-standard PPTX.
  • People who want export artifacts automatically proofread instead of eyeballing every slide.

Examples

  1. "Save as PDF" → skips the format question, produces deck-r3.pdf, then verifies page count, backgrounds, and fonts.
  2. "Export PPTX" → LibreOffice conversion, thumbnail generation, slide-image inspection, re-export if overflow is found.
  3. "Both" → produces PDF + PPTX and records output paths in MEMORY.md and the task index.
