| check_dependency_license | Determine whether adding or keeping a single open source dependency creates a legal obligation, given how this project ships. Call this BEFORE adding a new dependency to a project, and when auditing an existing one. A permissive result means no source-disclosure duty; a blocked result means the license obligates you and the dependency should be replaced or the shipping model reconsidered. |
| check_manifest_licenses | Scan an entire dependency manifest and report every dependency whose license creates an obligation for this shipping model. Use when reviewing a project as a whole, preparing for due diligence, or after a large dependency change. Pass a package-lock.json when one exists: problematic licenses usually arrive as transitive dependencies rather than ones you added directly, and only a lockfile reveals those. |
| explain_license | Given an SPDX license identifier or expression, explain what it requires across every shipping model at once. Use when the question is about the license itself rather than a specific package — for example when comparing AGPL-3.0 against GPL-3.0 for a hosted service, or deciding what a project may safely depend on. |
