YAML Frontmatter Management

Standardize YAML frontmatter properties across all vault content.

When to Use This Skill

Activate when you need to:

• Add or update frontmatter in markdown files
• Ensure consistent property naming and formatting
• Format tags, dates, or other property values
• Validate frontmatter structure

Note: This skill manages frontmatter PROPERTIES (keys, values, types, formatting). For document STRUCTURE (heading hierarchy, section order, frontmatter position), use obsidian-markdown-structure skill.
