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: 0.80). The SKILL.md instructs the agent to run Ahrefs actions (e.g., Get Backlinks, Get Referring Domains, Get Pages, and proxy requests via Membrane) which fetch details and content (referring pages, anchor text, page titles/snippets) from arbitrary public websites via the Ahrefs API, and the agent is expected to read and act on those results—exposing it to untrusted third-party content that could carry indirect prompt injections.
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 relies on the Membrane CLI at runtime (e.g., the command membrane connection ensure "https://ahrefs.com" --json) and Membrane responses can include clientAction.agentInstructions that are returned at runtime and directly instruct the AI agent, so this external content can control agent instructions.
