process-vault-frontmatters

You can automatically add YAML frontmatter to Obsidian markdown files by recursively scanning your vault to generate missing title and summary fields. This process ensures consistent metadata across all notes without manual editing.

The deduplication logic skips reprocessing unmodified notes by checking a 'processedAt' timestamp against the file's last modification time. It only acts on notes modified after their last processing timestamp that lack required fields.

Yes, you need Python 3 and the PyYAML library installed to standardize Obsidian vault metadata. These dependencies are required for the script to parse existing YAML blocks and generate new frontmatter fields.

The best way to ensure consistent title and summary fields is to run an automated script that extracts the title from the filename and the summary from the first useful paragraph. This enforces uniform metadata across your knowledge base.

Yes, you can update the 'processedAt' timestamp without overwriting existing metadata. The process intelligently updates only the timestamp and missing fields, preserving your existing valid YAML frontmatter values.
