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 explicitly instructs the agent to fetch CVE details from the public CIRCL CVE API (https://cve.circl.lu/api/cve/{CVE-ID}) and to use the "research" skill to browse vendor advisories and GitHub/security web pages, which are untrusted third‑party sources that the agent must read and that can materially influence mitigation and action decisions.
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: 0.80). The skill explicitly instructs the agent/user to clone and then build/run code from the remote repository git@github.com:mckinsey/agents-at-scale-ark.git (and fork variants), which means runtime fetching of that repo is a required dependency and its contents may be executed locally as part of the fix/test workflow.
