GitHub Flavored Markdown Skill for AI Systems

**Version:** 1.2.0 **Status:** Production Ready **Last Updated:** 2026-01-23

Overview

This skill transforms AI-generated markdown from "close enough" to "perfect." It provides comprehensive guidance for creating GitHub Flavored Markdown (GFM) that passes markdownlint validation with zero violations.

Purpose

AI systems frequently generate markdown that looks correct but fails automated validation due to missing blank lines, inconsistent formatting, or structural issues. This skill eliminates those problems by providing:

• Complete markdownlint rule coverage
• Pre-generation checklists
• Post-generation validation steps
• Common error patterns and corrections
• Real-world examples and templates

Key Features

• Zero Violations Goal: Generate markdown that passes markdownlint immediately
• Comprehensive Rule Coverage: All critical markdownlint rules documented with professional quality additions
• Professional Standards: URL wrapping, document structure, accessibility
• Invisible Character Detection: Identifies and prevents nbsp/tab issues
• Error Prevention: Catch common mistakes before they happen
• Practical Examples: Correct vs incorrect patterns for every rule
• VSCode Compatible: Works seamlessly with popular validation tools
