# Known Packages Registry

These npm package names are auto-detected when `usePackageJson: true` is set in `openPolicy()`. The plugin reads `dependencies` and `devDependencies` from the project root `package.json` and matches entries against this registry. Multiple package names can map to the same service — deduplication is by service name, first match wins.
