Zero-heavy data breaks a single regression, and the +1 log-transform hack does not save it. How I split CLV prediction into a hurdle classifier and an amount regression, with the two mistakes that bite in production.
Telex is Automattic’s experimental tool for generating block themes from a prompt. What the output actually contains, the templates you have to ask for, and why I test every generated ZIP in Playground first.
The Connectors API gives WordPress one registry for external services, starting with AI providers. Notes on the init lifecycle, the unregister and register dance for overrides, and the keys that sit unencrypted in wp_options.
Shadow AI shows up because the official workflow is slower than the shortcut. Here is how I read that usage as a signal, and what a governed option looks like inside a WordPress stack.
AI coding assistants write PHP that reads fine and falls over in production. A WooCommerce audit, the naive fetch they keep producing, and the refactor I run it through.
Gemini Embeddings 2 is in public preview: one vector space for text, images, audio and video. The preview limits, calling it from WordPress with the HTTP API, and why cosine similarity on its own still is not enough.
Generating a thousand lines of PHP takes seconds, so review is where the time goes. The review skill I run before opening a PR, why I ask for HTML reports, and the WooCommerce checkout bug that nearly shipped.
Prompt caching takes up to 90% off input token cost and around 80% off latency, but only when the prompt prefix never moves. Here is how the pre-fill stage works, where the 1,024-token threshold sits, and how to order a prompt so it hits the cache.
A single noisy A/B test made a client drop a feature that was working. Bayesian thinking is the correction: write down what you believed before the data arrived, then update it. Includes the mammogram problem and a five-step checklist.
I moved a 500-line prompt into a Claude Code Skill and stopped re-pasting it every morning. This covers the three loading stages, how to write a description Claude will act on, and the three implementation patterns.
