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 | $0.00019 | $0.00492 |
| Opus 5 | $0.00010 | $0.00246 |
| Sonnet 5 | $0.00004 | $0.00098 |
| Haiku 4.5 | $0.00002 | $0.00049 |
Grade A, and why
molclaw-mol2mol-sampling 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 5d 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.

Mol2Mol Molecule Generation
Note:
- Local files are not directly accessible by the server. Please upload them to the server using

The description of tool reinvent_mol2mol_sampling.
Generate new molecules sampling from the input molecule using different priors ('similarity': broad exploration, 'medium_similarity': balanced exploration, 'high_similarity': conservative optimization, 'scaffold': strict scaffold preservation, 'scaffold_generic': generic scaffold preservation, 'mmp': MMP-style local modifications).
Args:
smiles (str): Input SMILES string
n (int): Number of molecules for sampling
min_similarity (float): Required minimum similarity threshold (commonly 0.6)
prior_type (str): Required prior type; options: ['scaffold_generic', 'scaffold', 'mmp', 'similarity', 'high_similarity', 'medium_similarity'] (commonly 'similarity')
lipinski (bool): Required flag controlling Lipinski filtering (commonly True)
filter_preset (str): Required filter preset; options: ['none', 'minimal', 'default', 'strict'] (commonly 'default')
Return:
status (str): success/error
msg (str): message
save_smiles_file (str): Path to the saved SMILES file
output_smiles_list (List[str]): List of generated SMILES strings
How to use tool reinvent_mol2mol_sampling:
response = await client.session.call_tool(
"reinvent_mol2mol_sampling",
arguments={
"smiles": smiles,
"n": n,
"min_similarity": min_similarity,
"prior_type": prior_type,
"lipinski": True,
"filter_preset": filter_type
}
)
result = client.parse_result(response)
output_smiles_list = result["output_smiles_list"]
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.

molclaw-mol2mol-sampling is a skill published in the GitHub repository InternScience/MolClaw (33 stars, last pushed 28d ago), licensed MIT. It adds 19 tokens to every session and 492 once invoked, about $0.0001 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.
