smiles-validation
GitHub提供严格的SMILES分子结构验证、结构对比及修改确认功能，用于检测LLM生成的无效分子或结构不一致问题，支持单条校验、批量处理及变更分类。
触发场景
生成SMILES后需进行有效性校验
需要验证分子结构修改是否符合描述
批量检查生成的分子库质量

SMILES Validation
Overview
LLMs frequently generate invalid SMILES or produce molecules that don't match their stated reasoning. This skill provides strict validation, structural comparison, and modification verification.
Key checks:
- Parse validation: RDKit sanitization, valence checking, parenthesis/bracket balance
- Structural comparison: Tanimoto similarity, scaffold preservation, MCS analysis
- Modification verification: Confirm claimed structural changes exist in the actual molecule
- Classification: Categorize changes as optimization (>0.6 similarity), significant modification (0.4-0.6), or de novo design (<0.4)
When to Use This Skill
- After molecule generation: Validate every SMILES before reporting results
- Optimization verification: Confirm proposed modifications match the actual structure
- Batch validation: Check a library of generated molecules for validity
- Quality control: Ensure reproducibility of molecular designs
Installation
pip install rdkit-pypi
Core Workflows
1. Validate a Single SMILES
python scripts/validate.py --smiles "c1ccccc1"
2. Compare Original vs Modified
python scripts/validate.py --original "c1ccccc1" --proposed "c1ccc(O)cc1" --check-modification "Added hydroxyl group"
3. Batch Validation
python scripts/validate.py --input generated_molecules.csv --output validation_report.json
