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 5.1 | $0.00045 | $0.03798 |
| Opus 5 | $0.00023 | $0.01899 |
| Sonnet 5 | $0.00009 | $0.00760 |
| Haiku 4.5 | $0.00005 | $0.00380 |
Grade A, and why
smiles-to-iupac 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 11d 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 — 455 lines — stays where its author put it; the contents beside it link to each section on GitHub.

↓ 失败
4. RDKit-InChI → 生成 InChI → 返回
PubChem PUG-REST API (首选)
- 来源: NCBI PubChem (>1 亿化合物)
- 优势:
- 权威数据源,准确率最高
- 直接返回 IUPAC 名称
- 覆盖药物、天然产物等
- 限制:
- 需要网络连接
- 速率限制:~10 请求/秒
NCI/CADD Chemical Identifier Resolver (备选)
- 来源: NCI/CADD
- 优势:
- 权威数据源
- 支持多种化学标识符
- 准确率与 PubChem 相当
- 限制:
- 需要网络连接
- 某些化合物可能无 IUPAC 名称
STOUT (Docker) (本地方案)
- 架构: Docker 容器 + RDKit
- 优势:
- 本地运行,保护隐私
- 不依赖外部 API
- 生成 InChI 标准化标识
- 限制:
- 需要安装 Docker
- 需要安装
stout包
RDKit-InChI (最终方案)
- 来源: RDKit + InChI
- 优势:
- 完全本地运行
- 生成标准化 InChI
- InChI 可转换为 IUPAC
- 限制:
- 返回 InChI 而非直接 IUPAC

# 指定输出目录
python3 scripts/smiles_to_iupac.py -s "CCO" -o ./results
# 不计算分子性质(加快速度)
python3 scripts/smiles_to_iupac.py -s "CCO" --no-properties
# 安静模式(输出 JSON)
python3 scripts/smiles_to_iupac.py -s "CCO" -q
What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
- 11d ago First seen · 455 lines · 45 tokens per session scan A 03dc82d660cd
smiles-to-iupac is a skill published in the GitHub repository InternScience/ChemClaw (52 stars, last pushed 5mo ago), licensed MIT. It adds 45 tokens to every session and 3,798 once invoked, about $0.0002 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.
