obsidian-yaml-frontmatter

YAML frontmatter standardization enforces consistent property names, formatting, and value types across your vault's markdown files. This Skill applies a single YAML block at the top with lowercase keys, dash-formatted lists for tags, proper quoting for special characters, and dates in YYYY-MM-DD format to prevent duplicate keys and automation errors.

The Skill standardizes core properties including title, created, tags, source, author, sources, links, attendees, and event_date. It enforces lowercase naming, stores tags as plain-text YAML lists without hashtags, and ensures proper quoting for strings with special characters.

Consistent YAML frontmatter prevents misquoted values, duplicate keys, and inconsistent formatting that hinder search and automation. Standardized properties enable reliable querying, filtering, and bulk processing across your vault's markdown content.
