molclaw-hdock-tool

molclaw-hdock-tool is a skill for Claude Code, Codex from InternScience/MolClaw. It costs 24 tokens per session (1,090 once invoked), scanned A, original, MIT.

A protein-docking tool that predicts how two protein or peptide structures may join and ranks the resulting models. It accepts coordinate-based PDB files and saves each run’s files and summary measurements.

In plain words
What is it for?
Use it for structure-based docking, generating ranked complex models, setting receptor binding-site restraints, and reviewing saved docking outputs.
Why use it?
It helps examine possible protein–protein or protein–peptide interactions without manually testing every orientation.

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-hdock-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.

HDOCK Protein Docking

Note:

  • Local files are not directly accessible by the server. Please upload them to the server using molclaw-file-transfer before execution.
  • For PDB file inputs, it is recommended to preprocess them using molclaw-pdbfixer before execution.
  • Please refer to skill molclaw-scp-server to complete tool invocation.

Usage

1. HDOCK Protein Docking

The description of tool hdock_tool.

Run HDOCKlite protein-protein/protein-peptide docking and return the unique run directory, key files, and summary metrics for structure-based screening workflows. Inputs must be non-degenerate PDB coordinate files; SDF/PDBQT inputs are rejected before HDOCK is launched. The server chooses the output directory and may remap the partner chain in its internal copy to avoid receptor/partner chain collisions.
Args:
    receptor (str): Receptor PDB file path.
    ligand (str): Ligand or partner PDB file path.
    nmax (int): Number of docking models to generate (default 100).
    no_complex (bool): Disable complex structure generation (default False).
    angle (int): Rotation sampling interval in degrees (default 15).
    rsite (str|None): Optional receptor binding-site residue file.
    lsite (str|None): Optional ligand binding-site residue file.
Return:
    status (str): success, partial_success, or error execution status.
    msg (str): Human-readable execution summary.
    output_dir (str): Unique run directory under tool_result/hdock_tool_result.
    receptor (str): Resolved receptor input path.
    ligand (str): Resolved ligand input path.
    nmax (int): Effective model count upper bound used.
    no_complex (bool): Effective no-complex flag used.
    angle (int): Effective angle parameter used.
    rsite (str|None): Effective receptor site file used.
    lsite (str|None): Effective ligand site file used.
    output_files (dict): Key generated file paths such as Hdock.out, topN.pdb, and best models.
    partner_chains (List[str]): Partner chain IDs present in generated complex models. For protein-peptide complexes, pass output_files["best_model_pdb"] and partner_chains[0] to interaction_visualizer(mode="peptide").
    metrics (dict): Summary metrics including generated model count and best docking score when available.

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-hdock-tool is a skill published in the GitHub repository InternScience/MolClaw (33 stars, last pushed 29d ago), licensed MIT. It adds 24 tokens to every session and 1,090 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.
