Verify image files open, match requested dimensions, show the requested subject/product, and have no severe artifacts.
Checks
Confirm required input files exist.
Confirm output files or written plans match the skill contract.
Product/asset: the featured hero is the brand's real product (or app UI for SaaS), matching the
kit asset — not a mascot, logo, or placeholder standing in for the product.
Brand alignment: colours come from the intended source (the reference's palette for
style_source: template, the kit's documented colors for brand) — no invented/off-brand
colour (e.g. an accent pulled off a logo or mascot). Typography matches the kit's fonts.
Text/logo: copy and label text are real and correctly spelled; any logo is the brand's correct,
undistorted mark.
