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
Skill-creator’s eval viewer path ingests user-authored free text at runtime by embedding `feedback.json` (which the reviewer can type into in the browser) and passing it back via `/api/feedback` in `eval-viewer/generate_review.py`.
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 eval viewer includes an external JavaScript library that will be fetched and executed in the user's browser at runtime (https://cdn.sheetjs.com/xlsx-0.20.3/package/dist/xlsx.full.min.js), which is remote code execution triggered as part of the skill's viewer workflow.
