Low-risk findings.
2 low severity findings. Worth noting, but not necessarily harmful.
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
The skill’s Phase 0/3 intake path ingests outsider-authored ad copy (headline/body/CTA/text-in-image description/landing-page URL) and then, in Phase 2/3, fetches Meta policy pages and reasons over the outsider-provided copy against those fetched texts.
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
The skill explicitly fetches live policy text at runtime from https://transparency.meta.com/policies/ad-standards/ and uses that fetched content as the ground truth (quoting policy text and driving verdicts), so this external URL directly controls the agent's prompts/outputs.
