Agent Skills: fa-product-money-gate

Provides the money-gate evaluation discipline for the product-discovery lifecycle - pre-registered thresholds, net-of-fee revenue math (store commission, refunds, chargebacks, fraud, tax), LTV:CAC and payback checks, a cashflow/working-capital check, deflated willingness-to-pay, and pass/fail/kill routing along loop-back edges. Use at every stage gate to decide advance, loop-back, or kill for consumer one-off / in-app-purchase products.
