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 explicitly navigates to and automates arbitrary user-provided or external URLs (SKILL.md step to "ask for URL" when no dev servers are found and many examples using page.goto to user/third‑party sites), and run.js + lib/helpers.js include code that fetches page content and link hrefs (e.g., detectDevServers, page.goto, page.request.head, extractTableData, handleCookieBanner), so untrusted public web content will be ingested and can influence subsequent automated actions.
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
run.js may call npm install and npx playwright install chromium at runtime, which fetches and executes packages from the npm registry (https://registry.npmjs.org) (and associated Playwright browser download hosts), so the skill relies on remote code fetched and executed during runtime.
