Bio-Babel (Stanford, Qiu Lab): 17 R bioinformatics libraries rebuilt natively in Python with agent-ready contracts

Bio-Babel rebuilds classic R bioinformatics libraries natively in Python (no runtime bridges) and ships each with a machine-readable contract so AI agents call it correctly. The project site lists 17 libraries live on PyPI, 1,606 contracted symbols and 21 public repositories (the project's own counts); GitHub org Bio-Babel. AI-for-science item, not phage-specific.
