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 defines agent tools that fetch and ingest arbitrary public web content (e.g., summarize_url uses fetch(url) and search_web calls a public Brave Search API in references/example-outputs/ai-web-app.md and templates/AGENTS_CONFIG.md), so untrusted third-party pages/URLs would be read and could materially 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: 0.80). The skill includes runtime fetching of arbitrary webpages in summarize_url (fetch(url)) which is then injected into the LLM prompt via context.env.AI.run (and also calls the Brave Search API at https://api.search.brave.com/res/v1/web/search), meaning external content fetched at runtime can directly control agent prompts.
