Craig Armstrong developed enhancements for container SBOM tooling within the snyk/cli and snyk/user-docs repositories, focusing on improving authentication, archive format support, and SBOM generation. He introduced new command-line options in TypeScript to enable user authentication and credential handling, expanded support for docker-archive, oci-archive, kaniko-archive, and tar inputs, and implemented archive detection to prevent parsing errors. His work in CLI development and container security improved usability and compliance workflows, allowing developers to onboard faster and manage security requirements more effectively. Documentation updates in Markdown ensured clear guidance for users, reflecting a thorough and practical engineering approach.
