molclaw-equiscore-tool

molclaw-equiscore-tool is a skill for Claude Code, Codex from InternScience/MolClaw. It costs 30 tokens per session (2,226 once invoked), scanned A, original, MIT.

A scientific workflow for extracting molecular binding pockets and scoring molecules with EquiScore. A binding pocket is the part of a protein where another molecule may attach; PDB and SDF are common molecular structure file formats.

In plain words
What is it for?
Use it with docking-result SDF files and receptor PDB files to extract pockets, prepare individual molecule files, and run or validate EquiScore screening.
Why use it?
It organizes the file preparation and scoring steps needed to evaluate molecules against a protein target.

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

molclaw-equiscore-tool 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 6d 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.

Usage

1. Pocket Extraction

The description of tool equiscore_pocket.

Extract binding pockets from docking results and prepare split single-molecule SDFs for EquiScore screening.
Args:
    docking_result (str): Path to a docking-result SDF file.
    receptor_pdb (str): Path to the receptor PDB file.
    pocket_cutoff (float|None): Optional numeric cutoff for pocket detection.
    dry_run (bool|None): If True, validate inputs and prepare outputs without executing EquiScore.
Return:
    status (str): 'success' or 'error'.
    msg (str): Human-readable summary or error message.
    command (str): The subcommand executed ('get_pocket').
    run_dir (str|None): Run-specific directory under tool_result/equiscore_result.
    single_sdf_dir (str|None): Path to directory containing split single-molecule SDFs.
    pocket_dir (str|None): Path to the generated pocket folder.
    split_sdf_count (int|None): Number of split SDF files created.
    pocket_item_count (int|None): Number of pocket entries generated.
    sample_single_sdfs (List[str]|None): Sample single-SDF filenames.
    sample_pockets (List[str]|None): Sample pocket directory names.

How to use tool equiscore_pocket :

response = await client.session.call_tool(
    "equiscore_pocket",
    arguments={
        "docking_result": "relative/path/to/docking_result.sdf",
        "receptor_pdb": "relative/path/to/receptor.pdb",

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-equiscore-tool is a skill published in the GitHub repository InternScience/MolClaw (33 stars, last pushed 29d ago), licensed MIT. It adds 30 tokens to every session and 2,226 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.
