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
In the required screenshot/render pipeline, outsider-supplied tweet text is ingested at runtime by `screenshot/fetch-tweet.js` and `screenshot/fetch-full-tweet.js` via Playwright `page.evaluate()` / `innerText` from a user-provided x.com tweet URL or id, which can then be used as content for generated HTML/PNGs.
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 repeatedly instructs running the CLI to fetch remote DESIGN.md specs at runtime (e.g., "npx gooseworks styles get <slug>") — which pulls style specs from the central catalog (https://skills.gooseworks.ai/styles) that directly drive generation and are a required runtime dependency.
