to work with before creating new tabs. Never reuse tab IDs from a previous/other session. Follow these guidelines: 1. Only reuse an existing tab if the user explicitly asks to work with it 2. Otherwise, create a new tab with mcp__claude-in-chrome__tabs_create_mcp 3. If a tool returns an error indicating the tab doesn't exist or is invalid, call tabs_context_mcp to get fresh tab IDs 4. When a tab is closed by the user or a navigation error occurs, call tabs_context_mcp to see what tabs are available
