tachikoma-frontmatter

Frontmatter validation checks entities against a schema to detect missing required fields, invalid values, and formatting inconsistencies. This Skill reads your schema definition and entity files, identifies issues, and generates decision files proposing concrete fixes to standardize metadata across tasks, notes, roles, and other entity types.

Schema validation ensures entity metadata follows a defined structure, enabling consistent data quality and reliable downstream tooling. This Skill detects deviations—missing fields, wrong types, inconsistent formatting—and proposes corrections in batch decisions rather than manual entity-by-entity edits.

Yes. When multiple entities have similar frontmatter issues, this Skill batches them into single decision files, reducing manual review overhead. It creates decisions proposing grouped updates and tracks changes in the tachikoma-summary file.

The Skill reads .claude/schema.yaml to understand required and optional fields, then globs your entity directories to validate against that schema. It respects your existing structure and proposes changes aligned to your defined metadata requirements.

It generates decision files in decisions/ proposing frontmatter changes, updates the tachikoma-summary.yaml file to track validation results, and leaves original entities unchanged until you review and apply the proposed fixes.

Fixes are proposed as decisions you can review first, allowing you to inspect and approve changes before applying them. This prevents unwanted overwrites while automating detection and batching of common metadata problems.
