deepchem

deepchem is a skill for Claude Code from K-Dense-AI/drug-discovery-agent-skills. It costs 89 tokens per session (2,756 once invoked), scanned A, a copy of deepchem, MIT.

A Python toolkit for turning molecules into numerical descriptions that machine-learning models can use. It includes fingerprints, chemical descriptors, three-dimensional shape features, and learned representations.

In plain words
What is it for?
Use it to prepare molecular features for property prediction, toxicity or ADMET modelling, drug discovery experiments, and other chemistry or biology machine-learning tasks.
Why use it?
Different models need different ways to represent a molecule, and preparing them separately can make experiments inconsistent. This provides one interface for comparing and reusing those representations.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

deepchem scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/graph_neural_network.py, scripts/predict_solubility.py, scripts/transfer_learning.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

DeepChem

Overview

DeepChem is a comprehensive Python library for applying machine learning to chemistry, materials science, and biology. Enable molecular property prediction, drug discovery, materials design, and biomolecule analysis through specialized neural networks, molecular featurization methods, and pretrained models.

Checked against: deepchem 2.8.0 (PyPI stable, released 2024-04-02; still the current release as of August 2026). Requires Python 3.7–3.11 (<3.12 on PyPI). Core utilities (loaders, featurizers, MoleculeNet) work without a DL backend; GNN and transformer models need the matching extra (torch, tensorflow, or jax). Install the backend framework first when using GPU builds.

The release you install is much older than the code you will read about. The GitHub repository is actively developed, but 2.8.0 (April 2024) is still the newest tagged release, so pip install deepchem gives you code roughly two years behind master while the online docs and tutorials describe master. If an API in the documentation does not exist in your install, that gap is the reason. Either pin to 2.8.0 and use the 2.8.0 docs, or install from git (pip install git+https://github.com/deepchem/deepchem.git) and accept an untagged build.

When to Use This Skill

This skill should be used when:

  • Loading and processing molecular data (SMILES strings, SDF files, protein sequences)
  • Predicting molecular properties (solubility, toxicity, binding affinity, ADMET properties)
  • Training models on chemical/biological datasets
  • Using MoleculeNet benchmark datasets (Tox21, BBBP, Delaney, etc.)
  • Converting molecules to ML-ready features (fingerprints, graph representations, descriptors)
  • Implementing graph neural networks for molecules (GCN, GAT, MPNN, AttentiveFP)
  • Applying transfer learning with pretrained models (ChemBERTa, GROVER, MolFormer)
  • Predicting crystal/materials properties (bandgap, formation energy)
  • Analyzing protein or DNA sequences

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
