    Amazon ASD 2025 - Required Elements Check
    Verifies all mandatory layout elements are present in the design.
    """

    def __init__(self):
        prompt = """You are performing a visual quality-control check on an Amazon marketing asset. Your task is to verify that all required layout elements are present in the design.

IMPORTANT — SCOPE BOUNDARY: This check evaluates ONLY whether the required layout elements are physically present in the design. Do NOT penalise for locale/country errors (wrong URL, wrong language) — those are evaluated by the separate amazon_logo_country check. If the logo element exists but shows the wrong country URL, score the element as PRESENT. Score based on element presence, not content correctness.

AMAZON REQUIRED ELEMENTS:
Amazon marketing layouts contain the following elements:

CRITICAL ELEMENTS (must be present — absence is a major issue):
1. HEADLINE - The main promotional text (e.g. "Four days of big deals", sale messaging). This should be the largest and most prominent text element in the layout. It is always left-aligned.

2. BOX - The Amazon branded box graphic that contains the Amazon logo (or URL logo for emerging locales). This is a distinctive cardboard box shape with tape/flaps. In some display formats, a Paper Bag may be used instead of the Box.

IMPORTANT ELEMENTS (should be present in most formats):
3. DATE - The sale dates/timing information (e.g. "8-11 July", "8-11 luglio"). Usually positioned below or near the headline.

4. LEGAL LINE - Small disclaimer/legal text, typically at the bottom of the layout (e.g. "Exclusively for Prime members", "Solo per i clienti Prime"). Usually displayed in smaller, semi-transparent text.

OPTIONAL ELEMENT (nice to have, but NOT required for all formats):
5. SUBHEAD - Secondary text providing additional context (e.g. discount percentage, "Save up to XX%", additional promotional messaging). This is separate from the date.
   - IMPORTANT: Many formats — especially OOH (Out of Home), DOOH, and simplified layouts — do NOT include a separate subhead. This is perfectly acceptable. The date text or campaign branding can serve as the secondary text element.
   - Do NOT penalise an asset for missing a subhead if the layout otherwise contains a headline, box, date, and legal line.
   - Only flag a missing subhead as a minor note, never as a primary reason for failure.

EXCEPTIONS FOR SMALL FORMATS:
- For very small formats (typically below 60 pixels in height), the layout may be reduced to just: Headline and Box/logo only. This is acceptable.
- For banners where one side is smaller than 49 pixels, the Amazon logo (white) may appear without the box.

ADDITIONAL ELEMENTS (not required but note if present):
- CTA (Call-to-Action) button - Used in digital display formats only.
- ASINs (product images) - Used in certain layouts only.
- Campaign branding text (e.g. "Prime Day", "amazon prime day") - Often appears near the bottom.

STEPS TO EVALUATE:
1. Scan the entire layout and identify each element present
2. Determine if this is a standard format or a small format
3. For standard formats: verify the CRITICAL elements (Headline, Box) and IMPORTANT elements (Date, Legal Line) are present
4. Note whether a subhead is present, but do not treat its absence as a failure
5. For small formats: verify at minimum the Headline and Box/logo are present

DECISION CRITERIA:
- PASS: Headline AND Box are present, plus Date and Legal Line are present in standard formats
- FAIL: Headline is missing, OR Box/logo is missing in a standard format
- MINOR ISSUES (reduce score slightly but do not fail): Date missing, Legal Line missing, or Subhead missing
