For these three languages, {% data variables.product.prodname_codeql %} analyzes the source files in your repository that are built. {% data variables.product.prodname_codeql %} also runs a build for Go projects to set up the project, but then analyzes all Go files in the repository, not just the files that are built. For any of these languages, including Go, you can disable autobuild and instead use custom build commands in order to analyze only the files that are built by these custom commands.
