molecular-docking

A computational workflow that predicts how a small molecule may fit into a protein, using the protein structure and molecule structure as inputs. It prepares both structures, generates possible binding poses, examines their interactions, and ranks them.

In plain words
What is it for?
Use it to prepare protein and ligand structures, find likely binding pockets, dock molecules with AutoDock Vina or DiffDock, analyze contacts such as hydrogen bonds, and rank poses or compounds.
Why use it?
It removes the need to assemble separate preparation, docking, scoring, and interaction-analysis steps. This helps compare many molecules or binding poses in a consistent workflow.

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

molecular-docking 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 3d ago.

The scan reads SKILL.md. This mod also ships 5 executable files (scripts/dock.py, scripts/prepare_ligands.py, scripts/prepare_target.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Molecular Docking Pipeline

Overview

This skill provides a complete end-to-end molecular docking workflow covering every stage from raw protein structure to ranked, annotated binding poses. It integrates classical physics-based docking (AutoDock Vina) with modern deep-learning approaches (DiffDock), and includes protein-ligand interaction fingerprinting for downstream analysis.

Pipeline Stages:

  1. Target Preparation -- Clean PDB structures, remove waters, add hydrogens, detect binding pockets
  2. Ligand Preparation -- Convert SMILES to 3D, generate conformers, assign charges
  3. Docking -- Run Vina or DiffDock to generate binding poses
  4. Scoring & Interaction Analysis -- Identify hydrogen bonds, hydrophobic contacts, pi-stacking, salt bridges
  5. Ranking -- Combine docking scores with interaction quality into a composite ranking

When to Use This Skill

Use this skill when the user requests any of the following:

  • "Dock this ligand to a protein" or "predict how a molecule binds"
  • "Prepare a protein for docking" or "clean this PDB file"
  • "Find binding pockets" or "detect active sites"
  • "Run virtual screening against a compound library"
  • "Score docked poses" or "analyze protein-ligand interactions"
  • "Rank docking results" or "find the best binders"
  • Any structure-based drug design task involving PDB files and small molecules
  • Lead optimization where binding pose context is needed

Do NOT use this skill for:

  • Binding affinity prediction (use MM/GBSA or free energy perturbation tools)
  • Protein-protein docking (use HDOCK or ClusPro)
  • Covalent docking (requires specialized workflows)
  • Homology modeling (use AlphaFold or ESMFold first, then dock)

Related Skills

  • diffdock: For DiffDock-specific deep learning docking with all configuration options. This pipeline skill already calls DiffDock internally.
  • denovo-design: For generating novel molecules to dock. Combine with this skill for a complete design-dock workflow.
  • admet-prediction: For filtering docking hits by ADMET properties before experimental testing.

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.

molecular-docking is a skill published in the GitHub repository synthetic-sciences/openscience (3,385 stars, last pushed yesterday), licensed Apache-2.0. It adds 38 tokens to every session and 2,341 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.
