Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00056 | $0.05997 |
| Opus 5.5 | $0.00022 | $0.02399 |
| Sonnet 5.5 | $0.00011 | $0.01199 |
| Haiku 4.5 | $0.00006 | $0.00600 |
Grade A, and why
mol-paper-renderer 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 1mo 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 — 647 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Publication-Quality Molecular Renderer
使用 xyzrender 生成论文级分子结构图。这不是普通的分子查看器,而是专门为科研出图设计的自动渲染工具。

- 需要过渡态(TS)结构、非共价相互作用(NCI)展示
- 需要分子轨道(MO)、电子密度、静电势表面
- 需要晶体结构、晶胞、周期性结构
- 需要旋转 GIF 动画用于演示
- 需要凸包(convex hull)标注芳香环或配位 sphere
- 提供 cube 文件、ORCA/Gaussian/Q-Chem 输出文件
- 普通分子可视化但要求高质量输出

What ships with it
3 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.
- 1mo ago First seen · 647 lines · 56 tokens per session scan A b728f19416f2
mol-paper-renderer is a skill published in the GitHub repository InternScience/ChemClaw (53 stars, last pushed 6mo ago), licensed MIT. It adds 56 tokens to every session and 5,997 once invoked, about $0.0002 per session on Opus 5.5. 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.
