Answer free-text analytics questions about Stripe data stored in this project's D1 database (stripe_sync) by generating SQL, running it via wrangler, and returning a results table (plus optional chart). Use this skill whenever the user asks anything analytical or aggregate about Stripe entities — revenue, products, prices, subscriptions, customers, segments, charges, payments, refunds, disputes, payouts, top-N rankings, time-of-purchase patterns, period-over-period comparisons, conversion rates, in-store vs online, MRR/ARR — even if they don't explicitly mention SQL, D1, or the database. Trigger on questions like "which products generate the most revenue", "top 10 products last month", "subscription mix by plan", "what hour of day do customers buy most", "in-store vs online revenue", "churned customers this quarter", "average order value by country".
