Thanks for the report! Looks like this should be fixed if we exported declare const configs = { recommended: {... rules: 'error' | 'off' | 'warn'}} instead of rules: string. e.g. something like adding 'error' as const to this line

@poteto Do you know how the released index.d.ts is generated? It doesn't look to be in our build script

This seems to be fixed as of 19.0.0-beta-aeaed83-20250323. Thanks!
