Security audit

Cloud

Security checks across malware telemetry and agentic risk

Overview

This cloud-storage advice skill is mostly guidance, but it asks for command execution authority that is not clearly needed or bounded for that purpose.

Review this skill before installing because it can request command execution even though its useful function appears to be advisory cloud-storage guidance. Use it only if your agent environment can restrict or require confirmation for shell commands, and independently verify cleanup advice before deleting synced files because cloud deletions can propagate across devices.

Intent-Code Divergence

Medium
Confidence
93% confidence
Finding
The manifest exposes the `exec` tool while the documentation claims the skill only provides guidance and does not perform API-style actions. This capability/documentation mismatch can mislead users or calling agents into granting and invoking execution privileges that are unnecessary for the stated purpose, increasing the risk of unintended command execution or abuse.

Vague Triggers

Medium
Confidence
88% confidence
Finding
The usage flow and example tell the agent to process broadly described tasks without tightly scoping allowed operations, decision boundaries, or prohibited actions. In a skill that has `read` and `exec` tools, vague invocation semantics can cause overreach, such as acting on ambiguous user requests or performing unnecessary file/system operations.

Missing User Warnings

Medium
Confidence
90% confidence
Finding
The cleanup and sync guidance discusses deletion, duplicate backup shutdown, and storage management, but does not prominently warn that deletions in synchronized folders can propagate across devices and services. In this context, users may follow advice that leads to irreversible data loss, especially when they misunderstand sync versus backup behavior.
