molclaw-docking-screening

molclaw-docking-screening is a skill for Claude Code, Codex from InternScience/MolClaw. It costs 44 tokens per session (1,147 once invoked), scanned A, original, MIT.

A workflow for screening ten or more drug-like molecules against a protein target. It filters molecules, predicts how they may fit the protein, and combines the results to rank them.

In plain words
What is it for?
Filtering compounds, running QuickVina2 docking, rescoring with EquiScore, and selecting promising molecules for laboratory follow-up.
Why use it?
It reduces a large list of molecules to a ranked set of candidates for further study.

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-docking-screening 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 4d 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.

Description

This skill performs autonomous, large-scale virtual screening for a protein target using a soft pipeline:

  1. Drug-likeness filtering (QED and Lipinski)
  2. QuickVina2
  3. EquiScore
  4. Consensus ranking via rank aggregation

It is designed for 10+ molecules and should adapt strategy to input size, target quality, and tool outcomes.

Use this skill when:

  • The task is virtual screening for 10+ ligands.
  • The user asks for ranking, prioritization, or top-hit selection.
  • You need balanced use of physics-based docking and ML rescoring.

Workflow Steps

Stage 0. Input Validation and Setup

  • Validate SMILES list is non-empty and count >= 10 for this skill. If <10, still run but skip aggressive prefiltering.
  • Determine run mode from task objective:
    • complete-ranking mode: user asks for all molecules ranked (common in MolBench-vs).
    • top-n mode: user asks for best N only.
  • Resolve target structure:
    • If receptor_pdb_path exists, use it.
    • Else resolve target_chembl_id/uniprot_id and retrieve PDB.
  • Optional chain extraction if chain is specified.
  • Repair receptor with molclaw-pdbfixer (add hydrogens, remove waters/heterogens, normalize structure).
  • Record all chosen settings in an execution summary for reproducibility.

Stage 1. Property Filtering (Adaptive)

  • Compute QED and Lipinski violations for all candidates.
  • Default filter: QED >= 0.2 and Lipinski violations <= 2.
  • Soft adaptation by library size:
    • 10-50 molecules: keep default thresholds.
    • 51-200 molecules: consider stricter QED (e.g., 0.25-0.30) only if enough survivors remain.
    • 200 molecules: apply stronger triage and keep a broad but manageable subset for docking.

    • If survivors < max(top_n, 5), relax thresholds once and continue.

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-docking-screening is a skill published in the GitHub repository InternScience/MolClaw (33 stars, last pushed 28d ago), licensed MIT. It adds 44 tokens to every session and 1,147 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.
