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.
