Overview

This is a coherent mutation-testing skill, but it may temporarily change source files and install test tools as part of its stated job.

Install this only if you want an agent to run mutation testing in your codebase. Use a clean branch, disposable checkout, or container; review any package installs first; and ensure tests are not configured to hit production services or real credentials.

Vulnerability Patterns

• Prompt Injection: Instruction Override, Hidden Instructions, Exfiltration Commands
• Data Exfiltration: External Transmission, Env Variable Harvesting, File System Enumeration
• Privilege Escalation: Excessive Permissions, Sudo/Root Execution, Credential Access
• Supply Chain: Unpinned Dependencies, External Script Fetching, Obfuscated Code
• Excessive Agency: Unrestricted Tool Access, Autonomous Decision Making, Scope Creep

Missing User Warnings

Medium

• Confidence: 96% confidence
• Finding: The skill instructs the agent to directly modify source files in-place using commands like `sed -i` and temporary backup/restore operations, but it provides no explicit warning, confirmation step, or safer isolation mechanism. This is dangerous because it can unintentionally alter a user's working tree, break builds, overwrite local changes, or leave mutated code behind if the process is interrupted or restoration fails.
