 **Response:** MSDO supports these security analysis tools: antimalware (Windows only), bandit, binskim, checkov, eslint, templateanalyzer, terrascan, and trivy. Tools are automatically detected based on your repository content, or you can specify them explicitly. See the [Tools documentation](https://github.com/microsoft/security-devops-action/wiki) for details.
 
 **User reports:** "Trivy is failing with container image not found"
-**Response:** This error typically occurs when Docker isn't available. Trivy requires Docker for container scanning. Please ensure you have `docker/setup-buildx-action@v3` in your workflow before the MSDO action. Can you share your workflow YAML so I can help verify the configuration?
