Security checks for vulnerabilities and agentic risk

Overview

This is a small local JAX helper for numerical array work, with no evidence of hidden network access, credential use, persistence, or destructive behavior.

Install only if you are comfortable running a local Python helper on files and functions you provide. Prefer .npy or .npz for arrays, avoid loading pickle files from untrusted sources, and check output paths before saving because save operations can overwrite files.

Missing User Warnings

Medium
Confidence
97% confidence
Finding
The skill explicitly recommends pickle as a format for saving arrays without warning that pickle is unsafe for untrusted data. In practice, users often pair save/load guidance together, and normalizing pickle in documentation can lead to later unsafe deserialization, which may enable arbitrary code execution when malicious pickle files are loaded.
