3 findings — 3 medium severity. This skill can be installed but you should review these findings before use.
W011: Third-party content exposure detected (indirect prompt injection risk)
What this means
The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.
Why it was flagged
Third-party content exposure detected (high risk: 0.90). The skill's required PowerShell provisioners fetch and execute public third‑party code—e.g., DownloadString('https://community.chocolatey.org/install.ps1') in the Chocolatey install step and Install-Module PSWindowsUpdate—which ingests untrusted web-hosted scripts/modules that can materially alter build behavior.
W012: Unverifiable external dependency detected (runtime URL that controls agent)
What this means
The skill fetches instructions or code from an external URL at runtime, and the fetched content directly controls the agent’s prompts or executes code. This dynamic dependency allows the external source to modify the agent’s behavior without any changes to the skill itself.
Why it was flagged
Potentially malicious external URL detected (high risk: 1.00). The skill's PowerShell provisioner executes remote code at runtime via iex ((New-Object System.Net.WebClient).DownloadString('https://community.chocolatey.org/install.ps1')), so https://community.chocolatey.org/install.ps1 is fetched and executed during the build.
W013: Attempt to modify system services in skill instructions
What this means
The skill prompts the agent to compromise the security or integrity of the user’s machine by modifying system-level services or configurations, such as obtaining elevated privileges, altering startup scripts, or changing system-wide settings.
Why it was flagged
Attempt to modify system services in skill instructions detected (high risk: 1.00). This skill contains PowerShell provisioners that configure WinRM, modify firewall rules, install Windows features, stop/start services, and remove files under C:\Windows — all administrative actions that change the host/image system state and require elevated privileges.
