Meta Tags - SEO Tag Generator
Verdict safe, but 1 finding (1 medium), mainly unauthorized tool use. Most recent scan 2026-02-06.
This skill is a wrapper for an external npm package that generates SEO meta tags. The primary security concern is the unverified third-party package installation without version pinning or security validation, creating supply chain risk. The skill itself contains no malicious code, prompt injection attempts, or data exfiltration patterns. However, it lacks important metadata (license, compatibility, allowed-tools) and provides no guidance on error handling or resource limits. The skill appears legitimate in purpose (SEO meta tag generation) but requires users to trust an external package without verification mechanisms. Overall risk is MODERATE due to supply chain concerns, but there are no indicators of intentionally malicious behavior.

Findings
MEDIUM Unverified Third-Party Package Installation Unauthorized Tool Usellm
The skill instructs installation of an npm package '@lxgicstudios/meta-tags' from a third-party source without any verification, version pinning, or security validation. This creates supply chain risk as the package could be compromised, contain malicious code, or be subject to typosquatting attacks. The skill provides no provenance information, security audit details, or package integrity verification.

What we checked
- Static analyzer. Pattern rules over SKILL.md and bundled files: known-bad commands, exfiltration URLs, secrets, obfuscation.
- Behavioral analyzer. Checks what the skill asks the agent to do against what its description claims it does.
- Llm analyzer. A language model reads the skill and reports intent-level issues the rules cannot express.
- Trigger analyzer. Looks for instructions that fire on conditions the user did not ask for.
- Meta analyzer. A second model pass that validates, deduplicates and re-scores the other analyzers' findings.
What we did not check
- Runtime behaviour. The skill was not executed; findings come from reading its files.
- Anything fetched at install or run time, including remote scripts, package dependencies, and URLs the skill tells the agent to open.
- Content the analyzers cannot read: images, binaries, and some non-English text.
- Known scanner bypass classes. See the methodology and limitations page.
