Cowork-native fork of obsidian-vault-lint. Weekly maintenance pipeline (broken-link cleanup, MOC coverage, alphabetical sort, xAI-assisted connection discovery, Topic-MOC proposals, plus a top-3 reading-recommendation phase that surfaces the newest Library notes matching your research interests) that runs without the Obsidian CLI dependency. Pure-Python over the vault's markdown filesystem — safe to invoke from a Cowork scheduled task in the Linux sandbox. Schedule weekly for a self-maintaining knowledge base.
