2 findings — 2 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 "Remote Code Loading" workflow explicitly instructs adding a runtime resolver (ScriptManager.shared.addResolver) that points to external CDN URLs (e.g., `https://my-cdn.com/assets/${scriptId}`) so the app will fetch and execute remote chunks, which is a clear ingestion of untrusted third‑party content that can materially change 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: 0.90). I flagged https://get.flashlight.dev because the skill explicitly instructs running curl https://get.flashlight.dev | bash to install Flashlight, which fetches and executes remote code at runtime and is presented as a required tool for the measurement workflow.
