FAQPage Schema

How do I validate markdown files for syntax and formatting errors?▼

Markdown validation checks your documentation files for syntax errors, header hierarchy issues, unbalanced code fences, broken links, and formatting inconsistencies. Run the Skill on single or multiple files to catch problems before commit and enforce documentation standards across your project.

Can I use markdown validation in a CI pipeline?▼

Yes. Markdown validation integrates into CI pipelines to automatically check documentation quality on every commit or pull request. It reports PASS/FAIL with detailed error messages, making it suitable for enforcing standards during code reviews or pre-commit hooks.

What markdown formatting issues does validation detect?▼

Validation detects syntax errors, broken header hierarchies, unbalanced code fences, invalid tables and lists, trailing whitespace, link validity problems, and frontmatter requirement violations. It ensures consistent formatting standards across your documentation.

Do I need to configure frontmatter requirements for markdown files?▼

Markdown validation supports frontmatter requirements as part of its quality checks. You can enforce frontmatter standards alongside syntax and formatting validation to maintain metadata consistency in your documentation files.

How does markdown validation differ from a basic linter?▼

Markdown validation goes beyond basic linting by checking header hierarchy, link integrity, code fence balancing, table formatting, and frontmatter compliance. It provides comprehensive documentation quality assurance rather than surface-level syntax checking.

What happens when markdown validation finds errors?▼

Validation reports detailed error messages for each issue found, including error type, location, and description. Results show PASS/FAIL status, allowing you to fix problems before deployment or merge.
