What problem does it solve? Duplicate pages and unresolved named entities silently pollute a knowledge base when content is copied or migrated in without checks. This Skill enforces a pre-write quality gate so every new page is resolved against existing entities and deduplicated before it lands. ## Core Features & Use Cases - Named-Entity Resolution: Resolves people, companies, projects, and concepts registry-first via gbrain entity, expanding through aliases before concluding anything is new. - Semantic Dedup Decision Tree: Searches for the core claim, reads the top hit, and assigns a clear-dup / plausible-dup / clear band that decides write, link, or skip. - Delegation and Verification: Routes approved writes to enrichment skills (ingest, enrich, concept-synthesis) and verifies results with backlink checks. - Use Case: When asked to "move these project notes into the brain," the gate checks each file for existing entity pages and duplicate insights, links duplicates instead of cloning them, and only writes genuinely new content. ## Quick Start Ask the agent to migrate your notes folder into the brain while checking for duplicates before writing anything.
