📝 Markdown

Standards and validation checks for creating and editing markdown files.

When to Use

• Creating or editing any .md file
• Writing documentation, READMEs, specs, ADRs, or any prose content
• Converting existing content to markdown
• Reviewing or updating existing markdown for compliance

📐 Line Width

Hard-wrap all prose at 120 columns. Each paragraph line must be ≤ 120 characters.

Exceptions — never wrap:

• Fenced or inline code blocks
• URLs (never break mid-URL; if a URL alone exceeds 120 cols, leave it as-is)
• Table cell content that cannot be split without changing meaning
