Static Analysis

A comprehensive static analysis toolkit with CodeQL, Semgrep, and SARIF parsing for security vulnerability detection.

CodeQL and Semgrep skills are based on the Trail of Bits Testing Handbook:

• CodeQL Testing Handbook
• Semgrep Testing Handbook

Author: Axel Mierczuk

Skills Included

Skill	Purpose
codeql	Deep security analysis with taint tracking and data flow
semgrep	Fast pattern-based security scanning
sarif-parsing	Parse and process results from static analysis tools

When to Use

Use this plugin when you need to:

• Perform security vulnerability detection on codebases
• Run CodeQL for interprocedural taint tracking and data flow analysis
• Use Semgrep for fast pattern-based bug detection
• Parse SARIF output from security scanners
• Set up static analysis in CI/CD pipelines
• Aggregate and deduplicate findings from multiple tools

What It Does

CodeQL

• Create databases for Python, JavaScript, Go, Java, C/C++, and more
• Run security queries with SARIF/CSV output
• Write custom QL queries with taint tracking
• Integrate with GitHub Actions

Semgrep

• Quick security scans using built-in rulesets (OWASP, CWE, Trail of Bits)
• Write custom YAML rules with pattern matching
• Taint mode for tracking data flow from sources to sinks
• CI/CD integration with baseline scanning

SARIF Parsing

• Understand SARIF 2.1.0 structure
• Quick analysis using jq for CLI queries
• Python scripting with pysarif and sarif-tools
• Aggregate and deduplicate results from multiple files
• CI/CD integration patterns
