This gets you set up with CodeQL scanning, whether you're configuring GitHub Actions workflows or running the CLI locally. The skill covers the practical stuff like choosing between default and advanced setup, configuring language matrices with proper build modes, and troubleshooting compiled language analysis. It includes specifics on SARIF output, monorepo scanning with categories, and the CLI workflow from database creation through results upload. The compiled language support table and build mode guidance are especially useful since that's where most setup issues happen. Good reference if you're moving beyond one-click default setup or need to run CodeQL outside of GitHub's hosted environment.
