Validate and auto-repair YAML frontmatter on brain pages. Catches malformed pages before they enter the brain (missing closing ---, nested quotes, slug mismatches, null bytes, empty frontmatter, YAML parse failures). Wraps the gbrain frontmatter CLI for agent-driven workflows.
Run the frontmatter audit across your brain to identify issues, then run gbrain frontmatter validate <path> --fix to automatically repair them with backups.

YAML frontmatter validation audits brain pages against seven canonical validation classes to catch malformed structures, YAML parse failures, and empty frontmatter before ingestion. It wraps the gbrain frontmatter CLI for automated agent-driven workflows.
Frontmatter parsing fails when pages contain missing closing delimiters, nested quotes, slug mismatches, null bytes, or empty metadata blocks. Running an automated frontmatter audit surfaces these exact validation issues before page ingestion.
To automatically repair slug mismatches and missing delimiters, run an automated frontmatter audit with a fix flag. This repairs malformed YAML structures while creating optional backups and recording changes for traceability.
Yes, you can audit frontmatter consistency across multiple repositories. The validation process generates per-source reports to prevent silent audits and misapplied checks across repositories before multi-source brain content ingestion.
Yes, the validation logic shares a single source of truth with gbrain doctor's frontmatter_integrity checks. This ensures consistent integrity validation rules across both the automated audit workflows and the gbrain doctor environment.
