What problem does it solve? Keeping a study's Presenter's Companion in sync with its teaching deck is error-prone: slide counts drift, speaker notes go stale, and DOCX/PDF artifacts fall out of date. This Skill keeps the companion markdown as the single source of truth and regenerates all derived artifacts consistently. ## Core Features & Use Cases - Deck-companion alignment: Diff # Slide N headings against the .pptx slide count and order, then remap, add, or remove sections until they match. - Artifact regeneration: Build DOCX and PDF from companion markdown via _build_presenters_companion.py, and sync read-aloud scripts into PowerPoint notes panes from a JSON map. - Verification workflow: Run _verify_companion_outputs.py and the staged _build_presentations.py pipeline to validate slide counts, complete scripts, and layout before committing. - Use Case: After adding two slides to a study deck, update the companion markdown, rebuild the DOCX/PDF, sync speaker notes into the PPTX, and regenerate the deck and notes PDFs for a study-update PR. ## Quick Start Update the Presenter's Companion for my study so its slide sections match the deck, then rebuild the DOCX, PDF, and PowerPoint speaker notes.
