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

SKILL.md’s required runtime workflow points the agent to consult external coss docs/particle catalogs (e.g., `https://coss.com/ui/particles`, `https://coss.com/ui/llms.txt`, and GitHub URLs), which can be fetched at runtime as free-form web page text and then placed into the LLM context.

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 lists a "docs map for agents" URL that is intended for agents to fetch at runtime and thus can directly control agent instructions: https://coss.com/ui/llms.txt
