How does Semgrep differ from CodeQL within Claude Code?

Semgrep is optimized for speed and pattern-based matching, making it ideal for fast scans and custom linting. CodeQL is better for complex, interprocedural data flow analysis that spans multiple files.

Can I write my own security rules using this skill?

Yes, the skill provides extensive documentation on writing custom YAML rules using patterns, metavariables, and Boolean operators to target specific code patterns.

Does this skill support automated security in CI/CD?

Yes, it includes ready-to-use configurations for GitHub Actions and instructions for generating SARIF reports that integrate with security dashboards.

What is 'Taint Mode' in Semgrep?

Taint mode is a feature that tracks untrusted data (sources) as it flows through your application to potentially dangerous functions (sinks), helping identify injection vulnerabilities.

Which programming languages can I scan?

Semgrep supports a wide variety of languages including Python, JavaScript, TypeScript, Go, Java, C#, Ruby, and PHP through its official registry.

보안 및 테스팅

Performs rapid security scanning and custom pattern matching to identify vulnerabilities and enforce coding standards across diverse codebases.

Semgrep is a high-speed static analysis tool that enables developers to find bugs and security vulnerabilities using easy-to-write pattern matching rules. This skill allows Claude to execute fast security audits, develop custom YAML rules for specific codebase requirements, and implement taint-mode analysis to track untrusted data flow. It is particularly effective for enforcing best practices, detecting OWASP Top 10 issues, and integrating automated security checks into CI/CD pipelines without the overhead of complex semantic engines, making it the ideal first-pass analysis tool for modern development workflows.
