Low

Low-risk findings.

2 low severity findings. Worth noting, but not necessarily harmful.

Low

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

This skill’s required workflow explicitly uses runtime web fetching via firecrawl_scrape(url) / crawling_exa(url) to ingest full content from arbitrary external URLs (public web sources) into the agent’s LLM context, creating an indirect prompt-injection risk from outsider-authored free text.

Low

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 arbitrary external web pages at runtime via calls like firecrawl_scrape(url: "<url>") and crawling_exa(url: "<url>"), which injects remote content into the agent context and thus can directly control prompts/outputs.
