A client thought their WooCommerce recommendation engine was broken because accuracy at a 0.5 threshold read 51%. The ranking was fine, the threshold was not. This walks through checking AUC in a spreadsheet with sorted scores and the trapezoidal rule.
A client handed me an MVP he had built over a weekend in Cursor. It looked polished until I tried to add one calculation and found no schema underneath any of it. This is the case for settling the data model before you open a coding assistant.
A client once sent me a 50-page persona PDF that said nothing about why people abandon checkout. Functional personas built with AI from support tickets and order notes tell you what a customer is trying to finish and where they stop.
A WooCommerce client’s GPT search assistant was inventing products and discount codes. Prompt engineering did not fix it. Confidence thresholds, source links, and honesty about the limits did.
A client’s AI-built WooCommerce analytics dashboard crashed the moment we filtered by customer lifetime value. Rebuilding it meant sketching the data model and writing a DAL spec before touching any UI.
A client spent six months AI-powering their onboarding flow and ended up with hallucinated shipping dates. The prompt was never the problem, the context was. Here is what UX has to own before the model ships.
A mid-day flash sale took down a 30k-product WooCommerce shop and cost me three hours in Nginx logs. Here is what AI-driven server management does to that hunt, and where the automation stops.
An 85% churn score with no reason attached is a support ticket waiting to happen. What worked instead: a plain-language because statement, the charts behind a link, and code that maps feature names to words.
A Friday night emergency on a site I had not touched in six months cost me two hours of MAMP wrangling. WordPress Studio blueprints and selective sync are what I use now to keep client environments consistent.
Nobody checks whether $wpdb exists before running a query. The AI team wants models treated the same way in WordPress, with hosts providing the model and developers registering Abilities instead of wiring up API keys.
