close_tab
Close a specific browser tab by window and tab index, but use with caution due to high risk of targeting the wrong tab if tabs are reordered or closed. Recommended alternative: close_tab_by_id.
Instructions
⚠️ LEGACY DANGER: Close a specific tab using window/tab index. HIGH RISK of closing wrong tabs due to index shifting when tabs are reordered/closed. STRONGLY DEPRECATED: Use close_tab_by_id instead. Only use if Tab ID is unavailable.
