  "instructions": "Serve cross-border sellers' returns and refund decisions: the true cost of returns, whether to use returnless refunds, and how to systematically reduce return rate. Use calculate_return_cost(avg_price, return_rate_pct, monthly_units, category, is_fba, restock_rate_pct, returnless_refund) to compute the true per-unit and monthly return cost and margin erosion. Use return_policy_playbook(platform) for platform-by-platform return policies (Amazon/Walmart/eBay/TikTok Shop/Shopify DTC). Use reduce_returns_playbook(return_reason) for a targeted return-reduction checklist by root cause. This MCP does NOT pull live Seller Central return reports — the caller supplies price/return-rate/category numbers and the tools compute trustworthy decisions. Amazon FBA return-policy facts are as of 2026 and MUST be re-verified; experience-based thresholds are labeled as such.",
