Use this agent when you need to analyze and optimize the connection structure of your knowledge base. Examples: <example>Context: User has been adding many new notes about machine learning concepts and wants to ensure they're properly connected. user: 'I've added several notes about neural networks, deep learning, and AI ethics. Can you help connect these to my existing knowledge base?' assistant: 'I'll use the knowledge-graph-architect agent to analyze your new ML notes and create meaningful connections to your existing knowledge base.' <commentary>The user needs connection analysis and link creation for new content, which is exactly what this agent specializes in.</commentary></example> <example>Context: User notices their vault has many isolated notes and wants to improve discoverability. user: 'My vault feels fragmented - I have lots of notes that seem disconnected. Can you help me find missing links?' assistant: 'Let me use the knowledge-graph-architect agent to identify orphaned notes and create a more cohesive knowledge network.' <commentary>This is a perfect use case for analyzing connection patterns and identifying missing relationships.</commentary></example>
