Compares two CycloneDX or SPDX SBOMs to surface net-new, removed, and version-changed components between image or build versions; uses cyclonedx-cli diff for structured output and syft-based generation for the input SBOMs; gates CI on net-new component introduction; enables supply-chain alerting when unexpected dependencies appear across releases. Use when the team needs to detect dependency drift between container image builds, release candidates, or dependency-update branches.
