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
SKILL.md describes fetching particle “JSON URL”s from https://coss.com/ui/r/<particle-name>.json at runtime to obtain the “full source code”, which is outsider web-fetched content that can be read into the agent’s LLM context.
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 instructs the agent to fetch particle JSON manifests at runtime (e.g., https://coss.com/ui/r/<particle-name>.json and example https://coss.com/ui/r/p-accordion-1.json), which will retrieve external source code that is injected into the skill's runtime outputs.
