CRITICAL E005: Suspicious download URL detected in skill instructions.

• Suspicious download URL detected (high risk: 0.90). The agent-files link to a downloadable ZIP (release.zip) that the skill instructs users to unpack and install locally — a direct archive distribution on a non-standard file-hosting subdomain is an unverified installation vector and matches high-risk indicators; the other URLs are API/docs endpoints and are likely benign.

MEDIUM W011: Third-party content exposure detected (indirect prompt injection risk).

• Third-party content exposure detected (medium risk: 0.65). Outsider-authored free text can enter the LLM context via the runtime API response: the script calls POST /amazon/opportunity/reportByKeyword and then prints/uses the returned stdout/error msg content (from an external service) to stdout, which the agent can feed into its LLM context; this is not user-authored and is not bundled reference material.

MEDIUM W012: Unverifiable external dependency detected (runtime URL that controls agent).

• Potentially malicious external URL detected (high risk: 0.90). The SKILL.md explicitly instructs at runtime to download and install remote code from https://agent-files.linkfox.com/skills/linkfox-onboarding/release.zip when the onboarding skill is missing, which fetches and would install/execute external code.
