What problem does it solve? Editing an existing study companion PowerPoint deck without breaking its established design, footer numbering, speaker notes, or published PDF outputs is error-prone. This Skill guides in-place PPTX edits, layout verification, and staged PDF regeneration so slides, notes, and the companion study stay consistent. ## Core Features & Use Cases - Design-preserving PPTX edits: Modify slide content, figures, order, or count while keeping the deck's typography, palette, layouts, and speaker notes intact. - Layout and overflow verification: Run _check_deck_layout.py to catch text collisions, off-canvas spill, wrong N / M footers, and broken slide cross-references before publishing. - Staged PDF production: Rebuild the slides PDF and read-aloud notes PDF via _build_presentations.py --deck <ID> --in-place, which verifies outputs before replacing published files. - Use Case: After revising a study's definitions, update its companion deck's affected slides, renumber footers after removing a slide, then regenerate and visually verify both PDFs for a study-update pull request. ## Quick Start Update the Epistemology deck under Studies/ to reflect the revised definitions in the study markdown, then rebuild and verify its slides and notes PDFs.
