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: 1.00). The skill explicitly accepts arbitrary user-shared URLs and "Fetch the web page content" (see "2. URL Validation & Fetch" -> "Fetch the web page content" and the "Content Extraction" section), meaning it ingests untrusted public web content which is then analyzed and used to drive categorization, insights, and follow-up actions—allowing third-party content to influence agent 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). The skill explicitly fetches arbitrary user-supplied URLs at runtime (e.g., raw GitHub or pastebin URLs such as https://raw.githubusercontent.com/... or https://pastebin.com/...), injecting the fetched page content into the agent's processing/context for summary and insight generation, so external content can directly control prompts or model output.
