Second Brain Graph
undefined-ui/second-brain-osAnalyse the vault's link graph and report on its shape: orphan rate, average degree, components, hubs, bridges and clusters, with what each number means for retrieval. Use this skill when the user asks about the health or structure of their graph, wants metrics, asks which pages are most connected or most isolated, or asks whether the vault is fragmented. Do NOT use for fixing what it finds, which is second-brain-lint, or for answering a content question.
At a glance
This skill is for Research and helps you analyze vault structure and connectivity, identify orphaned and hub pages, and measure knowledge graph health.
