Skill Installer

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward GitHub skill installer, but users should treat installed repositories as trusted code because they persist new agent instructions locally.

Install only from GitHub repositories you trust, especially when using private-repo tokens. Review the target skill's SKILL.md before installing, and remember that installed skills persist across sessions and can influence future agent behavior.

Vague Triggers

Medium
Confidence
83% confidence
Finding
The invocation description is broad enough to match common user requests like installing or adding a skill from a GitHub URL, which can cause this skill to activate frequently in situations involving untrusted repositories. In this context, activation leads directly to network-based retrieval and local installation of persistent content, increasing the chance of importing malicious skills or unsafe instructions.
