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 required workflow calls a runtime HTTP relay (e.g., `curl -s https://r.jina.ai/{url}` / `markdown.new` / `defuddle.md`) which returns attacker-controlled webpage Markdown text from an outsider-supplied URL, and that returned free text is then read/printed (and thus becomes LLM-ingestible output) by the tool.
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's runtime scripts call third-party relay endpoints (e.g., https://r.jina.ai/{url}, https://markdown.new/{url}, https://defuddle.md/{url}) via curl/subprocess to fetch remote page content that is then returned/injected into agent output, so these URLs are runtime dependencies that can directly influence prompts.
