When should I use Semgrep instead of CodeQL?

Use Semgrep for fast scans, pattern matching, and single-file analysis. Use CodeQL when you need deep, interprocedural analysis across complex data flows in large, compiled codebases.

How do I integrate this into my development workflow?

The skill provides comprehensive guides for running local scans, using pre-defined rulesets like 'p/security-audit', and setting up automated GitHub Actions for every pull request.

What is the primary benefit of using the Semgrep skill with Claude Code?

It allows Claude to perform incredibly fast, pattern-based security audits, identifying common vulnerabilities and coding errors in seconds rather than hours.

Can this skill help me find SQL injection and XSS?

Yes, by using taint mode analysis, the skill can track untrusted user input from entry points to dangerous execution sinks, specifically targeting injection-style vulnerabilities.

Does this skill support custom security rules?

Absolutely. It provides full support for writing, testing, and deploying custom YAML-based Semgrep rules tailored to your specific codebase or framework.

Seguridad y Pruebas

Performs rapid security scanning and pattern-based vulnerability detection using Semgrep and Trail of Bits security rules.

Acerca de

This skill empowers Claude to execute high-speed security audits and static analysis using Semgrep, a leading tool for finding bugs and enforcing coding standards. It specializes in identifying vulnerability patterns such as the OWASP Top 10 and CWE Top 25 through both standard rulesets and custom YAML configurations. By leveraging taint mode data flow analysis, it can track untrusted input from sources to dangerous sinks, providing a robust first-pass security layer. Whether performing one-off manual scans or configuring automated CI/CD pipelines, this skill provides actionable security insights with minimal false positives.
