 ## Overview
-> New project — fill in during first session.
+Standalone Python CLI tool that benchmarks OpenAI Assistants against RAG knowledge bases. Built for Barclays to evaluate banner-creation assistants (Internal Banners, Social Posts, Display Banners, PPC) — generates test prompts from brand/compliance docs, runs them against the assistant N times in parallel, scores responses on quality/consistency/accuracy/completeness (1–10 via GPT-4o), and produces an HTML report with charts.
