Use a sub-agent: check this repo for virus, malware, trojan horse behavior or anything that might be obfuscated but is one of these attack vectors.
Specifically:
-
Maintainer information - does the code authors use real names or work with recognizable organizations and companies
-
Unexpected commits - has there been a commit by a maintainer who is not usually making contributions
-
Frequency and recency of the updates - does it look like the library is minding the updates or its own dependencies
-
Code review practices - Are PRs properly reviewed? Is there a multi-approver policy?
-
Security disclosure policy - Is there a security.md file or documented vulnerability reporting process?
-
Obfuscated code detection - Look for intentionally obscured code, minified JavaScript without source maps, or encoded strings that execute
-
Suspicious network activity - Check for outbound connections to unfamiliar domains, data exfiltration, or API usage without clear purpose
-
Sensitive file operations - Does the code access unexpected directories or modify system files?
-
Dependency analysis - Examine the supply chain security (transitive dependencies)
-
Known vulnerability scanning - Check if the repo has unpatched CVEs or security advisories
-
Excessive permission requests - Does the code request unnecessary system access?
-
Secrets management - Are there hardcoded API keys, tokens, or credentials?
-
Automated security testing - Does the repo use security scanning tools or SAST?
-
Documentation quality - Well-documented code is often a sign of quality and security consciousness
-
Community engagement - Active issue responses and community involvement often correlate with better security practices
Conclusion: Make a recommendation for whether this library is safe to use in a professional / production setting.
