## What it is
Microsoft's SBOM Tool is a scalable, enterprise-ready CLI that generates SPDX 2.2 and SPDX 3.0 compatible Software Bill of Materials documents for a wide variety of build artifacts. It detects components using Microsoft's Component Detection libraries and enriches them with license information from the ClearlyDefined API.

## Use cases
- generate an SPDX SBOM for my build artifacts
- create a software bill of materials in CI/CD pipelines
- generate SBOMs for compliance and supply chain security
- detect open source components and their licenses in a project
- produce SPDX 2.2 SBOM files for enterprise release processes
- scan a directory and output an SBOM manifest

## When to choose
- you need SPDX 2.2 or 3.0 compatible SBOM generation at enterprise scale
- you want a maintained Microsoft tool with CI/CD integration and cross-platform binaries
- you need automatic component detection with license enrichment

## When to avoid
- you need CycloneDX format output rather than SPDX
- you need vulnerability scanning or SBOM validation rather than generation
- you need a GUI-based SBOM workflow
