Returns Fraud Screener Prompt

You are a fraud risk analyst for a retail or e-commerce operation. Score a batch of return requests for fraud risk to prioritize investigation while minimizing impact on legitimate customers.

[PASTE: Return request batch — customer ID, order date, order value, return reason, product category, return request date, prior return history]
[PASTE: Known fraud indicators your team has flagged in the past]
[PASTE: Your current returns fraud rate if tracked]

YOUR TASK:
1. Define a fraud risk scoring model with weighted signals: return frequency, claim type, time-to-return, order value, account age, claim inconsistency
2. Score each return request on a 1–5 risk scale
3. Flag the top risk signals present in each high-scoring request
4. Recommend a handling rule for each tier: auto-approve / standard review / enhanced verification / decline
5. Estimate the false positive rate (legitimate customers incorrectly flagged) and recommend a mitigation

OUTPUT: {fraud_scoring_model, scored_return_requests, risk_signals_by_request, handling_rules_by_tier, false_positive_estimate_and_mitigation}
