Vault Frontmatter Maintenance

Offline, file-level repair of YAML frontmatter. Complements the properties skill (which uses the Obsidian CLI) by operating on .md files directly — safe for bulk mechanical passes.

When to Use

• Stripping the legacy id: field from a batch of notes
• Removing unrendered Templater markers (<% tp.file.cursor() %>, {{title}})
• Cleaning up null entries inside tags: lists
• Adding missing frontmatter blocks to notes that lack one
• Ensuring FVH notes carry context: fvh
• Normalizing tag case / pluralization drift
