 With a key, you get:
 - Auto-generated descriptions when you add nodes
-- Automatic dimension/tag assignment
+- Automatic node descriptions
 - Semantic search (find similar content, not just keyword matches)
 
 **Cost:** Less than $0.10/day for heavy use. Most users spend $1-2/month.

-**What happens:** Once connected, Claude calls `getContext` first to orient itself (stats, contexts, hub nodes, dimensions, available skills). It proactively captures knowledge — when a new insight, decision, person, or reference surfaces, it proposes a specific node (title, dimensions, description) so you can approve with minimal friction. For complex tasks it reads skills to follow your graph conventions and workflows.
+**What happens:** Once connected, Claude calls `getContext` first to orient itself (stats, contexts, hub nodes, available skills). It proactively captures knowledge. When a new insight, decision, person, or reference surfaces, it should propose a specific node with a strong title, description, source, and metadata. Context is optional and should only be set when the primary scope is obvious.
