ALWAYS use this skill when user says "Note that", "Remember that", "Add a note about", or explicitly asks about their notes with phrases like "What did I note about", "Show me my notes on", "Search my notes for", "Find in my notes", or "What have I noted about". This searches the user's persistent note-taking system (their second brain), NOT conversation history or general knowledge. Only trigger when the user explicitly mentions "note/notes/noted" or clearly refers to their personal knowledge system.
