# =============================================================================
# SHOWCASE 02 — QR Code Validator
# =============================================================================
# requires_llm: true
# category: advanced
#
# Downloads a QR code image, validates it with scan score analysis,
# extracts dimensions and thumbhash, then uses an LLM to produce
# a comprehensive QR quality report.

        Analyze these QR code validation results and write a quality report:

        ## Validation Results
        {{with.validation}}

        ## Image Dimensions
        {{with.dims}}

        ## Thumbhash
        {{with.thumbhash}}

        Include:
        1. Scan score interpretation (0-100 scale)
        2. Decoded content analysis
        3. Image size assessment for scanning reliability
        4. Recommendations for QR code improvements
        5. Mobile scanning compatibility notes
