Use when validating or repairing an editable PPTX deck for geometry, accessibility, native editability, source lineage, and OOXML package integrity.

PPTX Quality Gates Use this skill before delivering a generated PPTX. Treat deterministic failures as repair work, not exceptions. Workflow 1. Confirm the spec, builder, PPTX, source manifest, and audit paths. 2. Apply references/audit checklist.md to the coordinate contract before building. 3. Reopen the PPTX and compare slide count, actual bounds, hidden slides, and requested geometry with the layout tree. 4. For production decks, run pptx reference deck analysis/scripts/validate package.py and save the JSON report. 5. Check document language, slide titles, meaningful image alt text, reading order, table headers, and source references. 6. When a compatible renderer is already available, inspect previews for clipping, font fallback, contrast, crop, and hierarchy. Do not add a renderer dependency. 7. Repair the spec or task local builder, rebuild, and rerun the same checks. Required artifacts Keep the spec, PPTX, build record, geometry audit, accessibility audit, package report, and source manifest together. Report any documented exception with slide ID, object ID, owner, reason, and review date. Pass criteria Zero content collisions, text overflows, unsafe content bounds, invalid positive geometry, and package integrity errors. Meaningful slide content must remain native editable objects; images support rather than replace it. See references/audit checklist.md for the complete checklist.
