What problem does it solve? Over time a personal knowledge vault accumulates inconsistencies: mixed languages, broken wikilinks, duplicate people and project notes, malformed frontmatter, and stale content. Fixing these by hand across hundreds of notes is slow and error-prone, and bulk edits risk destroying append-only history. ## Core Features & Use Cases - Vault-wide operations: Re-language notes to a target language, normalize frontmatter, repair broken wikilinks, deduplicate people/projects, tidy formatting, and propose archives. - Safety-first workflow: Every run follows a scope → preview → confirm → batched apply → report loop, with one Git commit per batch so changes are reversible. - Protected content rules: Never deletes notes, preserves append-only timeline entries and the English "For future Claude" preamble, and confirms every duplicate merge. - Use Case: After a Vault Health Check flags orphans and duplicates, ask to clean up the vault; the skill previews representative diffs, waits for approval, then applies fixes in small committed batches. ## Quick Start Ask the assistant to tidy up the vault and fix broken links and duplicate people notes, previewing changes before applying them.
