AI isn't code

Ask a function the same question twice, you get the same answer. That's the contract. Ask an LLM the same question twice, you might get two different answers — both correct, phrased differently.

Most frustration with AI-assisted building comes from expecting the first contract while working with the second. The fix isn't prompting harder. It's briefing better: AI = context.

The problem, concretely

WebsitePublisher.ai is a platform where AI assistants build complete websites via MCP tools (59 of them) and REST APIs. Building a webshop touches 14 integrations: product catalog, cart, checkout orchestration, payments (Mollie/Stripe), inventory, invoicing, email, search, discounts, reviews, wishlist, abandoned-cart recovery, analytics, and shipping.
