markdownlint
Consistent Markdown for projects and teams.
Check Markdown and CommonMark against configurable rules for headings, spacing, lists, links, and other consistency issues. The JavaScript library powers companion command-line tools and a VS Code extension, making it useful in editors and CI. Custom rules and configuration adapt checks to a project, and supported violations can be fixed automatically.
