STRING PPI Query

Security checks for vulnerabilities and agentic risk

Overview

The skill is a straightforward STRING database query helper, with one optional example script that should be run only from a trusted environment.

This skill is reasonable to install for STRING protein interaction lookups. Treat the example script as development code: run it only from a trusted directory or virtual environment, and prefer importing open_biomed from an installed trusted package rather than relying on the script's sys.path modification.
