NameDescription
decode_qrcode_fullA

Scan the entire image for QR codes and decode them. Returns all detected codes with detailed diagnostics. Agent should decide next step based on result_code:SUCCESS → use content; SUCCESS_WITH_WARNING → check warnings;RETRYABLE → call enhance_and_decode;NO_QR_FOUND / QR_UNRECOVERABLE → inform user.

enhance_and_decodeA

Apply enhancement operations to a region of the image, then decode.Enhancement strategy is decided by the Agent based on decode_qrcode_full diagnostics.Supports upscale, sharpen, adjust_contrast, denoise — composable in any order.

auto_enhanceA

Automatically try enhancement strategies to decode a QR code in one call.Tries up to 7 strategies (upscale, sharpen, contrast, denoise, combos) in sequence — returns as soon as one succeeds.Ideal for RETRYABLE results from decode_qrcode_full:no manual bbox estimation or operation selection needed.
