string-database

string-database is a skill for Claude Code, Codex from synthetic-sciences/openscience. It costs 44 tokens per session (4,210 once invoked), scanned A, original, Apache-2.0.

A connection to STRING, a database of known and predicted relationships between proteins. These relationships can be explored as networks of proteins that may work together.

In plain words
What is it for?
Use it to retrieve protein-interaction networks, find interaction partners, run functional enrichment, compare species, and identify highly connected proteins.
Why use it?
It removes the need to assemble interaction evidence from many sources before beginning an analysis. It helps reveal partners, clusters, and important proteins in a network.

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 A, and why

string-database 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 2d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/string_api.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.

STRING Database

Overview

STRING is a comprehensive database of known and predicted protein-protein interactions covering 59M proteins and 20B+ interactions across 5000+ organisms. Query interaction networks, perform functional enrichment, discover partners via REST API for systems biology and pathway analysis.

When to Use This Skill

This skill should be used when:

  • Retrieving protein-protein interaction networks for single or multiple proteins
  • Performing functional enrichment analysis (GO, KEGG, Pfam) on protein lists
  • Discovering interaction partners and expanding protein networks
  • Testing if proteins form significantly enriched functional modules
  • Generating network visualizations with evidence-based coloring
  • Analyzing homology and protein family relationships
  • Conducting cross-species protein interaction comparisons
  • Identifying hub proteins and network connectivity patterns

Quick Start

The skill provides:

  1. Python helper functions (scripts/string_api.py) for all STRING REST API operations
  2. Comprehensive reference documentation (references/string_reference.md) with detailed API specifications

When users request STRING data, determine which operation is needed and use the appropriate function from scripts/string_api.py.

Core Operations

1. Identifier Mapping (string_map_ids)

Convert gene names, protein names, and external IDs to STRING identifiers.

When to use: Starting any STRING analysis, validating protein names, finding canonical identifiers.

Usage:

from scripts.string_api import string_map_ids

# Map single protein
result = string_map_ids('TP53', species=9606)

# Map multiple proteins
result = string_map_ids(['TP53', 'BRCA1', 'EGFR', 'MDM2'], species=9606)

# Map with multiple matches per query
result = string_map_ids('p53', species=9606, limit=5)

Parameters:

  • species: NCBI taxon ID (9606 = human, 10090 = mouse, 7227 = fly)
  • limit: Number of matches per identifier (default: 1)
  • echo_query: Include query term in output (default: 1)

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

string-database is a skill published in the GitHub repository synthetic-sciences/openscience (3,493 stars, last pushed today), licensed Apache-2.0. It adds 44 tokens to every session and 4,210 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 2026-09-03.
