Comments suppressed due to low confidence (2)

packages/rehype-shiki/src/minimal.mjs:1

• There are no tests for minimal.mjs. Consider adding tests to verify that the minimal highlighter exports (shiki, getLanguageDisplayName, highlightToHast, highlightToHtml) work correctly with the reduced language set.

import powershellLanguage from 'shiki/langs/powershell.mjs';

apps/site/next.mdx.plugins.mjs:3

• The import path for the plugin has changed—update the project’s README or migration guide to show @node-core/rehype-shiki/plugin as the new import source for rehypeShikiji.

import rehypeShikiji from '@node-core/rehype-shiki/plugin';
