SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Manually ensuring consistent and correctly formatted YAML frontmatter across numerous markdown files in a large worldbuilding project is tedious, error-prone, and hinders content discoverability. This Skill automates metadata management.

Core Features & Use Cases

  • Comprehensive Validation: Checks for mandatory fields, correct YAML syntax, Spanish language use, and proper relative paths.
  • Smart Tag Suggestion: Analyzes content to suggest relevant, existing tags (locations, characters, factions, concepts, periods) to maintain consistency.
  • Automated Correction: Detects and corrects common errors like English fields, incorrect spacing, tabulations, and missing mandatory fields (e.g., facciones for characters).
  • Use Case: Validate the metadata of your new character file, ensuring all fields are correctly formatted, tags are consistent with the corpus, and no mandatory fields are missing, saving you manual review time.

FAQPage Schema
How do I validate YAML frontmatter in Markdown files?

YAML frontmatter validation checks that mandatory fields (title, folder, description) are present, syntax is correct, keys are in English, and folder paths are relative. Run /check-metadata on your Markdown files to catch formatting errors and missing required fields automatically.

Can I automate tag suggestions for my content metadata?

Smart tag suggestion analyzes your Markdown content and recommends relevant, existing tags—locations, characters, factions, concepts, periods—maintaining consistency across your corpus without manual research or duplication.

What common metadata errors does frontmatter validation catch?

Validation detects English language field names, incorrect spacing and tabulation, missing mandatory fields, malformed YAML syntax, and non-relative folder paths, correcting them to ensure consistency across your content collection.

When should I validate metadata during my content workflow?

Run validation during Markdown creation or editing and after post-edit hooks to ensure new and modified files meet frontmatter standards. Use /suggest-tags when adding content to maintain tag consistency with existing entries.

Does frontmatter validation work with large worldbuilding projects?

Yes. The Skill scales to numerous Markdown files in large projects, automating consistent metadata management across your entire content corpus and reducing manual review overhead.

What happens if mandatory frontmatter fields are missing?

Validation detects missing mandatory fields like title, folder, and description, flags them as errors, and can auto-populate or recommend corrections to ensure complete metadata before files are considered valid.
