polymer-build

multiscale-materials-modelling

A Claude Code skill marketplace for multiscale materials modelling workflows. Each of the 22 skills installs individually — pick only the ones you need. Built for the SuperScientist agent framework, it covers molecular dynamics, quantum chemistry, machine learning potentials, and materials informatics — from building a simulation box to analyzing production trajectories.

Features

• Molecular dynamics — LAMMPS, GROMACS, and packmol for setting up and running atomistic and coarse-grained simulations
• Quantum chemistry — PySCF for HF/DFT/MP2 calculations and CP2K for periodic DFT and ab initio MD
• Machine learning potentials — MACE for fast, accurate energy and force predictions
• Materials informatics — Pymatgen and the Materials Project API for crystal structures, phase diagrams, and properties
• Cheminformatics — RDKit for SMILES parsing, descriptors, and substructure searches
• Analysis and visualization — ASE, freud, mdanalysis, matplotlib, and seaborn for trajectories and plots
• Optimization — Bayesian optimization for composition and property tuning via Ax/BoTorch
• Skill creator tooling — Built-in guidance for adding new multiscale materials modelling skills

When to Use Which Tool

Task	Recommended Skill
Build a polymer melt and equilibrate with LAMMPS	polymer-build → packmol → lammps
Run a protein-ligand simulation	gromacs
Compute a molecule's DFT energy or optimize its geometry	pyscf (gas phase) or cp2k (periodic)
Screen catalysts with a neural-network potential	mace
Get crystal structures and compute a phase diagram	materials-project → pymatgen
Analyze RDF or diffusion from a trajectory	freud or mdanalysis
Optimize a multi-component formulation	bayes-opt
Convert between CIF, POSCAR, XYZ, LAMMPS data	ase or pymatgen

Installation

Add the marketplace once:

/plugin marketplace add Chenghao-Wu/cc-skills-ZhenghaoWu-Group

Then install only the skills you need — each skill is its own plugin:

/plugin install lammps@multiscale-materials-modelling-marketplace
/plugin install rdkit@multiscale-materials-modelling-marketplace
/plugin install freud@multiscale-materials-modelling-marketplace

Or run /plugin to browse and install skills interactively. After installing, restart Claude Code (or run /reload-plugins) so the new skills load.

Python dependencies

A skill assumes its underlying library is available in your Python environment (for example freud needs freud-analysis, rdkit needs rdkit). Install what each skill needs, or install everything at once for development and testing:

git clone https://github.com/Chenghao-Wu/cc-skills-ZhenghaoWu-Group.git
cd cc-skills-ZhenghaoWu-Group
pip install -e ".[dev]"
