markdown-linting

This skill provides comprehensive guidance for markdown linting using markdownlint-cli2, the industry-standard markdown linter that can be used in any project.

This tooling enables enforcement of strict markdown quality standards through automated linting. Markdown files can be validated using markdownlint-cli2 with a unified tooling approach that ensures zero configuration drift across VS Code, CLI, and CI/CD environments.

markdownlint-cli2 supports multiple markdown flavors. By default, it validates GitHub Flavored Markdown (GFM), which is recommended for most projects.

Comprehensive markdown linting guidance using markdownlint-cli2. Run, execute, check, and validate markdown files. Fix linting errors (MD0XX rules). Configure .markdownlint-cli2.jsonc (rules and ignores). Set up VS Code extension and GitHub Actions workflows. Supports markdown flavors including GitHub Flavored Markdown (GFM) and CommonMark. Use when working with markdown files, encountering validation errors, configuring markdownlint, setting up linting workflows, troubleshooting linting issues, establishing markdown quality standards, or configuring flavor-specific rules for tables, task lists, and strikethrough.
