From Prompt Engineering to Harness Engineering: Why E-Commerce Agents Keep Failing

Jun 10, 2026

FREE$26.99

Coding tools figured out that the model is commodity and the harness is the product. E-commerce hasn't. We tested the market, found the gap, and engineered the solution.

The Tokenomics of the Product Listing Page: Why Agentic Commerce is Confined to Chat Bubbles

Jun 4, 2026

FREE$62.99

The chat carousel was a cost ceiling, not a product decision. Here are the tokenomics explaining why, and what we can do to move agents from bubbles onto the listing page, where most of the sales funnel lives.

The Merchant's AI Dilemma

Jun 3, 2026

FREE$61.99

E-commerce merchants face a discovery threat, but the obvious fix — wrapping a hosted LLM around legacy search — forces them to play by the economics of AI labs, not retail. This is an argument about compute scarcity, platform moats, and why the AI budget eventually comes out of something else.

Product Search Needs Better Evals

May 19, 2026

FREE$32.99

A product-search benchmark can miss the right product if nobody labelled it. Public evals are useful lab equipment, but commerce needs real queries, graded labels, images, metadata, and honest caveats about historical bias.

Beyond Average Revenue: A Four-Part Decomposition for Measuring Discovery Experiments

May 6, 2026

FREE$67.99

Mean revenue is a noisy metric for A/B tests in e-commerce - it conflates purchase probability, visit frequency, and basket size into a single estimand. We decompose them, fit each with an appropriate GLM, and embed the result inside a 2² factorial design to measure two platform features simultaneously. The approach recovers clean per-feature estimates even under a confounded allocation mechanism.
