mdc-chemistry-ml---pytorch-models

mdc-chemistry-ml---pytorch-models is a skill for Claude Code from GrayCodeAI/starling. It costs 27 tokens per session (138 once invoked), scanned A, original, MIT.

A guide for building deep-learning models for chemistry with PyTorch, a Python toolkit for machine learning. It covers molecular data, training, automatic differentiation, and graphics-card acceleration.

In plain words
What is it for?
Use it to design models such as graph neural networks for predicting molecular properties, prepare training data, calculate custom losses, and use a GPU when available.
Why use it?
It helps structure the many parts of training a chemistry model, from loading data in batches to adjusting learning rates and stopping training at the right time.

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

mdc-chemistry-ml---pytorch-models 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 7d ago.

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.

What it actually says

  • Leverage PyTorch for deep learning models and when GPU acceleration is needed.
  • Design neural network architectures suitable for chemical data (e.g., graph neural networks for molecular property prediction).
  • Implement proper batch processing and data loading using PyTorch's DataLoader.
  • Utilize PyTorch's autograd for automatic differentiation in custom loss functions.
  • Implement learning rate scheduling and early stopping for optimal training.
  • Use GPU acceleration when available, especially for PyTorch models.

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.
