SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill automates the extraction of key evidence slots from VAT invoices by converting them into a standardized card_features list, reducing manual data entry and increasing reliability.

Core Features & Use Cases

  • Rule-based extraction: captures required slots such as type, code, number, supplier and buyer details, amounts, and dates.
  • Enhanced extraction: enables additional analysis like business relationship insights and tax burden considerations.
  • Use Case: Upload an invoice image and receive a ready-to-use card_features payload for evidence cards in investigations.

Quick Start

To extract features from an invoice image, provide a YAML payload including evidence_materials with the image URL and identifiers, and specify whether to use the default rule-based mode or the enhanced mode.
