Security audit

Xxd Tool

Security checks across malware telemetry and agentic risk

Overview

This is a local hex-dump helper with no network, credential, persistence, or hidden behavior, though its documentation overstates what the included script actually does.

This appears safe to install from a security perspective, but verify what command actually runs before relying on it. Treat it as a simple local hex viewer unless you separately confirm the advertised reverse, patch, JSON, and bit-dump features, and only patch copies of important binaries.

Missing User Warnings

Medium
Confidence
91% confidence
Finding
The skill explicitly advertises binary patching and describes it as in-place byte modification, but provides no safety warning about irreversible file changes, corruption risk, or the need to operate on backups. In a binary analysis/reverse-engineering context, users may apply patches to firmware, executables, or configuration blobs, and an unsafe default workflow can easily damage critical artifacts or produce unbootable binaries.
