Best use case

chemistry is best used when you need a repeatable AI agent workflow instead of a one-off prompt.

Teams using chemistry should expect a more consistent output, faster repeated execution, less prompt rewriting.

When to use this skill

  • You want a reusable workflow that can be run more than once with consistent structure.

When not to use this skill

  • You only need a quick one-off answer and do not need a reusable workflow.
  • You cannot install or maintain the underlying files, dependencies, or repository context.

# Chemistry & Drug Discovery

## Overview
Computational chemistry, cheminformatics, and drug discovery workflows.

## Key Tools
- **RDKit**: Molecular manipulation, fingerprints, descriptors, substructure search
- **PubChem**: Chemical compound database (100M+ compounds)
- **ChEMBL**: Bioactivity database for drug-like molecules
- **Open Babel**: Format conversion, 3D generation
- **AutoDock Vina**: Molecular docking
- **GROMACS/OpenMM**: Molecular dynamics simulations

## Common Workflows

### Virtual Screening
1. Define target (protein structure from PDB)
2. Prepare compound library (from ChEMBL/ZINC/Enamine)
3. Filter by drug-likeness (Lipinski's Rule of Five)
4. Docking (AutoDock Vina, GNINA)
5. Scoring and ranking
6. ADMET prediction (absorption, distribution, metabolism, excretion, toxicity)
7. Hit validation

### QSAR Modeling
1. Curate activity data (ChEMBL IC50/Ki/EC50)
2. Calculate molecular descriptors (RDKit)
3. Feature selection
4. Model training (Random Forest, XGBoost, neural network)
5. Validation (cross-validation, external test set)
6. Applicability domain assessment

### Molecular Property Prediction
- Lipophilicity (LogP)
- Solubility (LogS)
- Permeability (PAMPA, Caco-2)
- Metabolic stability (CYP inhibition)
- hERG toxicity
- BBB penetration

xlsx

564
from beita6969/ScienceClaw

Use this skill any time a spreadsheet file is the primary input or output. This means any task where the user wants to: open, read, edit, or fix an existing .xlsx, .xlsm, .csv, or .tsv file (e.g., adding columns, computing formulas, formatting, charting, cleaning messy data); create a new spreadsheet from scratch or from other data sources; or convert between tabular file formats. Trigger especially when the user references a spreadsheet file by name or path — even casually (like "the xlsx in my downloads") — and wants something done to it or produced from it. Also trigger for cleaning or restructuring messy tabular data files (malformed rows, misplaced headers, junk data) into proper spreadsheets. The deliverable must be a spreadsheet file. Do NOT trigger when the primary deliverable is a Word document, HTML report, standalone Python script, database pipeline, or Google Sheets API integration, even if tabular data is involved.
