Billing

finance-billing-ops is an evidence-first skill for Finance Operations. Use it for revenue, pricing, refunds, team-seat logic, duplicate-charge questions, and billing-model checks when you need code-backed billing truth instead of generic payments advice. It is built for operator decisions, billing audits, and pricing comparisons.

ecc-tools-cost-audit is an evidence-first audit skill for ECC Tools cost spikes, runaway PR creation, quota bypass, premium-model leakage, and duplicate jobs. Use it for Backend Development investigations that trace a request from webhook to worker to billing decision and prove where spend is being created.
