Security checks across malware telemetry and agentic risk

Overview

This skill is a local skill-quality evaluator with read-only default behavior, but it includes an optional write mode users should invoke carefully.

Use it normally for read-only checks with --layer1 or --anti-patterns. Before using --auto-fix --allow-write, run the preview first and apply it only on a version-controlled or disposable copy, because it can modify SKILL.md and remove empty reference files in the target skill directory.

MCP Least Privilege
Confidence
87% confidence
Finding
The skill advertises no declared permissions, yet its documented usage and the associated analysis indicate read/write capabilities. Undeclared write access is dangerous because users and orchestrators cannot accurately assess what the skill may modify, which breaks least-privilege expectations and can lead to unintended file changes in skill directories.

High
Category
MCP Tool Poisoning
Confidence
95% confidence
Finding
The documented purpose presents the skill as a self-contained evaluation engine, but the observed behavior includes auto-fixing SKILL.md, creating backups, deleting empty files, and a write-capable mode. This mismatch is dangerous because users may invoke what appears to be a passive analyzer while actually granting a mutating tool the opportunity to alter or delete repository contents.
