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.md workflow explicitly instructs the agent to call navigate_page(url: "<target-url>") and to list/get network requests (e.g., list_network_requests, get_network_request) to load and analyze arbitrary target URLs, meaning it fetches and interprets open/public third-party site content as part of its decision-making.
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). The skill asks the user to add an MCP config that runs "npx -y chrome-devtools-mcp@latest", which at runtime fetches and executes remote npm package code that the skill relies on, so it is a required external dependency that executes remote code.
