## 1. Executive Summary

Design decisions in UI/UX work are currently made through a combination of intuition, tribal knowledge, and periodic A/B testing — but these three information sources rarely talk to each other. A designer proposes a variant, engineers run the test, results go into a spreadsheet, and the next designer starts from scratch. The A/B UI Variant Recommender closes this loop: it generates design variants informed by what has actually worked, improves from every test result and user selection it observes, and always explains exactly why it proposed what it proposed.

The system operates as an MCP (Model Context Protocol) server, integrating directly into AI coding tools like Claude Code, Cursor, and Windsurf. When a developer or designer asks for UI variants for a hero section, pricing table, or CTA button, the system retrieves the top candidates per domain from a curated corpus (style, color, typography, layout, UX patterns), anchors Variant 1 on the `ui-reasoning.csv` expert recommendation for that product/page context, then selects Variants 2 and 3 by maximizing embedding distance from already-chosen docs — guaranteeing visual diversity without pigeonholing into pre-defined strategy buckets. Strategy labels (e.g. "bold", "layered") are assigned pos…
