Luxury Commerce Fraud Inspection Agent using Claude Agents SDK and Replit Agent
High-value e-commerce returns require accurate authentication and rapid fraud detection to prevent financial leakage in premium retail. Build an automated return verification workflow using the Claude Agents SDK with extended thinking capabilities alongside Replit Agent tooling to inspect claim documentation and flag fraudulent buyer claims.
What you are building
The core problem, expected build, and operating context for this challenge.
Develop an automated luxury returns inspector using Anthropic's Claude Agents SDK with extended thinking to detect discrepancy signals in claim evidence.
How work is evaluated
Evaluates return fraud risk classification accuracy across sample claim scenarios.
Challenge datasets
Public datasets, plus the private datasets you have access to.
How submissions are scored
These dimensions define what the evaluator checks and which criteria separate a passable run from a strong one.
serial_mismatch_detected
Checks whether serial number mismatches are identified correctly.
This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.
fraud_detection_f1
F1 score on return fraud classification benchmark. • target: 0.92 • range: 0-1
This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.
