pocket-detection

pocket-detection is a skill for Claude Code, Codex from synthetic-sciences/openscience. It costs 41 tokens per session (3,219 once invoked), scanned B, original, Apache-2.0.

A tool for finding possible binding pockets on a protein structure and assessing whether those pockets may accept drug-like molecules. A binding pocket is a cavity where a small molecule can attach to a protein.

In plain words
What is it for?
Use it to detect pockets, score their druggability, compare pockets across protein structures, and create visual summaries.
Why use it?
It helps identify and compare likely drug-binding sites before docking or designing molecules for a target.

About the project

synthetic-sciences/openscience is an AI workbench that carries out scientific research by reading papers, forming hypotheses, writing and running code, conducting experiments, analyzing results, and preparing reports. Researchers use it for work in machine learning, biology, physics, and chemistry with remote or local models. Catalogue add-ons extend its scientific workflows through skills and instructions.

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 B, and why

pocket-detection scanned grade B with 1 finding 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 yesterday.

The scan reads SKILL.md. This mod also ships 5 executable files (scripts/compare.py, scripts/detect.py, scripts/druggability.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.

Pocket Detection & Druggability Assessment

Overview

This skill provides multi-method binding pocket detection on protein structures, druggability scoring, pocket visualization, and cross-structure pocket comparison. It is the first dedicated step in any structure-based drug design workflow — identifying where on a protein a small molecule can bind before docking or de novo design begins.

Key capabilities:

  • Three detection methods: grid-based cavity scan, fpocket (alpha spheres), P2Rank (machine learning)
  • Druggability scoring: 6-axis weighted assessment (volume, hydrophobicity, enclosure, depth, H-bond capacity, aromaticity)
  • Visualization: summary panels, residue composition, druggability radar, method comparison plots
  • Cross-structure comparison: match pockets across apo/holo, wild-type/mutant, or predicted/experimental structures

When to Use This Skill

Use the pocket-detection skill when you need to:

  • Find binding sites on a protein structure before docking
  • Assess druggability of detected pockets (can a drug-like molecule bind here?)
  • Compare pockets across multiple structures (e.g., apo vs holo, WT vs mutant)
  • Visualize pocket properties for reports or publications
  • Validate binding sites using multiple detection methods for consensus
  • Identify allosteric sites beyond the obvious orthosteric pocket

Trigger phrases: "find binding pocket", "detect active site", "druggability assessment", "pocket detection", "where does the ligand bind", "compare binding sites"

Do NOT use this skill for:

  • Actually docking ligands into pockets (use molecular-docking)
  • Predicting how tightly a ligand binds (use binding-affinity)
  • Protein structure prediction (use structure-prediction first, then this)
  • Protein-protein interaction surfaces (use ClusPro or HDOCK)

Related Skills

  • molecular-docking: Dock ligands into detected pockets. This skill's JSON output feeds directly into dock.py --center_x/y/z.
  • binding-affinity: Score docked poses for binding strength. Run after docking.
  • structure-prediction: Predict protein structure from sequence when no experimental PDB is available. Run before this skill.

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.

pocket-detection is a skill published in the GitHub repository synthetic-sciences/openscience (3,473 stars, last pushed today), licensed Apache-2.0. It adds 41 tokens to every session and 3,219 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
