Working notes on Shopify themes, apps, Plus and the odd opinion, written by the person doing the work, not a content team.

Discounts, shipping rules, and cart logic can live in a Function, an app, or both. A practical decision framework, with the trade-offs I weigh on real builds.
Letting Claude or ChatGPT answer questions about your store is genuinely useful — and genuinely risky if you wire it up wrong. The MCP pattern I use to keep it read-only and audited.
