Can Claude help me write custom CodeQL queries?

Yes, this skill provides a comprehensive syntax reference, core workflows, and structural guides for writing declarative, object-oriented QL queries.

When should I use CodeQL instead of Semgrep?

Use CodeQL when you need interprocedural analysis and complex data flow tracking; use Semgrep for simpler, single-file pattern matching and faster analysis times.

What is CodeQL used for in Claude Code?

It allows Claude to help you perform deep static analysis, find security vulnerabilities, and track data flow across complex codebases by querying code as a database.

Which languages does this CodeQL skill support?

The handbook provides patterns for C/C++, Go, Java/Kotlin, JavaScript/TypeScript, and Python.

How do I analyze a CodeQL database using this skill?

You can use the 'codeql database analyze' command with specific format flags like SARIF to generate detailed results that can be viewed in IDEs or CI/CD pipelines.
