CRITICAL E005: Suspicious download URL detected in skill instructions.

• Suspicious download URL detected (high risk: 0.80). The package distribution uses an unknown domain that instructs users to run curl | sh (cli.inference.sh) and fetch binaries from the same host with only an on-server checksums.txt (dist.inference.sh), a high-risk installer pattern because piping shell scripts and trusting same-origin checksums can easily be abused to deliver malware; the other top-result-*.com pages are just content pages and not the main risk.

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

• Third-party content exposure detected (high risk: 0.90). This SKILL.md explicitly instructs fetching and analyzing top-ranking public URLs (see "SERP Analysis Process" Step 2: infsh app run tavily/extract --input '{"urls": ["https://top-result-1.com/article", "https://top-result-2.com/article"]}' and related search commands), so the agent ingests untrusted, user-generated/open-web content that directly shapes its decisions and outputs, enabling indirect prompt injection.

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

• Potentially malicious external URL detected (high risk: 0.90). The skill's Quick Start tells users to run a remote installer that is fetched and executed at runtime via "curl -fsSL https://cli.inference.sh | sh" (which then downloads binaries from dist.inference.sh), so this URL chain executes remote code and is required for the infsh commands the skill demonstrates.
