Audit a project's dependency licenses against an explicit policy (allow-list / deny-list / review-required) and flag incompatibilities before they ship to production. Reads SPDX license identifiers from npm package manifests, Python METADATA / PKG-INFO files, and pyproject.toml; classifies each license by family (permissive, weak-copyleft, strong-copyleft, proprietary, unknown); detects copyleft contamination and SPDX-incompatible license combinations. Use when: pre-release legal review, M&A code-audit due diligence, preparing an OSS attribution NOTICE file, or switching a project's own license. Threshold: any GPL-family license in a project declaring MIT or Apache-2.0; any UNKNOWN-license package; any metadata-vs-source license mismatch. Trigger with: "check licenses", "license compliance audit", "SPDX scan", "GPL contamination check".
