What is the RDKit skill for Claude Code?

It is a specialized capability that allows Claude to provide domain-specific guidance, code snippets, and best practices for using the RDKit library in Python for chemical data tasks.

Does it support SMARTS substructure searching?

Absolutely. The skill includes guidance on defining query patterns using SMARTS to identify functional groups, rings, and complex molecular substructures.

Can Claude help calculate drug-likeness properties?

Yes, the skill covers the calculation of Lipinski's Rule of Five parameters, including molecular weight, LogP, and hydrogen bond donors/acceptors.

Can this skill help with 3D molecular modeling?

Yes, it provides instructions for 3D coordinate generation, conformer embedding, and geometry optimization using force fields like UFF and MMFF94.

When should I use RDKit over Datamol?

Use RDKit for advanced control, custom sanitization, and specialized algorithms; use Datamol for standard workflows requiring a simpler interface.
