-Compendium Scribe is a Click-driven command line tool and library that uses OpenAI's **deep research** models to assemble a comprehensive research compendium for any topic. The workflow combines optional prompt refinement (powered by `gpt-4.1`), an `o3-deep-research` call with web search tooling, and deterministic post-processing. It produces human-readable Markdown by default, backed by a rich XML data model that can also be exported.
