Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00061 | $0.01186 |
| Opus 5 | $0.00030 | $0.00593 |
| Sonnet 5 | $0.00012 | $0.00237 |
| Haiku 4.5 | $0.00006 | $0.00119 |
Grade A, and why
nmr-prediction 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 4d 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.
How it starts
The opening of the file, as written. The whole thing — 118 lines — stays where its author put it; the contents beside it link to each section on GitHub.
NMR Chemical Shift Prediction Skill
When to use this
Use this skill when the user provides a SMILES string and wants:
- Per-atom ¹H or ¹³C liquid-phase NMR chemical shifts (ppm)
- Simulated NMR spectrum image (Lorentzian line-shape)
- Quick deep-learning based prediction without DFT
Inputs
- SMILES string (required, e.g.
CCOfor ethanol) --nucleus H | C | both(optional, defaultboth)
Outputs
/tmp/chemclaw/nmr_1H_<smiles>.png— ¹H NMR spectrum/tmp/chemclaw/nmr_13C_<smiles>.png— ¹³C NMR spectrum- Console: per-atom chemical shifts (ppm)

模型权重(大文件,不放进 repo)存放于 /tmp/weights/,通过 --setup 自动下载。
环境安装 (首次)
1. 准备 assets/
# 将 NMRNet 放入 assets/(从 GitHub 下载 zip 后解压)
cp -r ~/Downloads/NMRNet-main nmr-prediction/assets/NMRNet
# 将 Uni-Core 放入 assets/ 并安装
cp -r ~/Downloads/Uni-Core-main nmr-prediction/assets/Uni-Core
cd nmr-prediction/assets/Uni-Core
python setup.py install # macOS 默认禁用 CUDA,直接执行
2. 安装 Python 依赖
cd nmr-prediction
pip install -r requirements.txt
# 如果还没装 torch:pip install torch (CPU 版即可)
3. 下载模型权重 + scaler → /tmp/weights/
cd nmr-prediction
python nmr_prediction.py --setup
此命令通过 remotezip 从 Zenodo 仅提取所需文件:
- H/C 模型 checkpoint(各 ~560 MB)→
/tmp/weights/finetune/liquid/.../ - H/C 液相 scaler(各 623 B)→ 同上目录
注意:NMRNet 仓库自带的
demo/notebook/scaler/是固态 NMR scaler,不适用于液相预测。 当前 skill 只保留 NMRNet 的精简推理代码与oc_limit_dict.txt,不依赖demo/数据目录。
How to run(环境已准备好时)
cd nmr-prediction
# 预测乙醇的 ¹H + ¹³C 谱
python nmr_prediction.py "CCO"
# 只预测苯的 ¹³C 谱
python nmr_prediction.py "c1ccccc1" --nucleus C
# 预测咖啡因的 ¹H 谱
python nmr_prediction.py "Cn1cnc2c1c(=O)n(c(=O)n2C)C" --nucleus H

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.
- 4d ago First seen · 118 lines · 61 tokens per session scan A ee6524a0721a
nmr-prediction is a skill published in the GitHub repository InternScience/ChemClaw (52 stars, last pushed 5mo ago), licensed MIT. It adds 61 tokens to every session and 1,186 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
