Validate‑Maintainers is a CLI tool for npm package authors that checks a custom `localMaintainers` field in `package.json` against the maintainers listed on the npm registry (or a specific GitHub/commit version). It helps projects ensure that publishing rights are explicitly recorded and that more than one person can maintain the package, reducing the “bus factor” for open‑source libraries. Intended for maintainers and CI pipelines that need to verify npm publishing authority.
