DeepMind ships Cheminformatics Skills for Antigravity, built on RDKit, ChEMBL and PubChem
Available now through Antigravity's Science plugin or npx skills add google-deepmind/science-skills/, the skills let the model orchestrate while RDKit and the ChEMBL and PubChem connectors do the deterministic chemistry. DeepMind's demo has an agent sift thousands of compounds and propose macrocycle designs in about an hour, and it stresses every design still needs lab validation.
