+# Tabs
+
+Use **CDP for control**, **UI automation for user-visible order**.
+
+## Pure CDP (portable: macOS / Linux / Windows)
+
+```python
+tabs = list_tabs()                    # includes chrome:// pages too
+real_tabs = list_tabs(include_chrome=False)
+tid = new_tab("https://example.com")  # create + attach
+switch_tab(tid)                       # attach harness to tab
+cdp("Target.activateTarget", targetId=tid)  # show it in Chrome
+print(current_tab())
+print(page_info())
+```
+
+What CDP is good at:
+- attach to a tab
+- open a tab
+- activate a known target
+- inspect URL/title/viewport
+- capture the attached tab's screenshot even if another tab is visibly frontmost
+
+What CDP is bad at:
+- matching the **left-to-right tab strip order** the user sees
+- telling whether the attached target is an omnibox popup / internal page without URL filtering
+
+## Visible order (platform UI)
+
+### macOS
+
+```applescript
+tell application "Google Chrome"
+  set out to {}
+  set i to 1
+  repeat with t in every tab of front window
+    set end of out to {tab_index:i, tab_title:(title of t), tab_url:(URL of t)}
+    set i to i + 1
+  end repeat
+  return out
+end tell
+```
+
+```applescript
+tell application "Google Chrome"
+  set active tab index of front window to 2
+  activate
+end tell
+```
+
+### Linux
+
+No AppleScript. Same split still applies:
+- use CDP for `new_tab`, attach, inspect, activate known targets
+- use window-manager / browser UI automation when the user means visible order
+
+Typical tools:
+- `xdotool`
+- `wmctrl`
+- desktop-environment scripting (`gdbus`, KWin, GNOME Shell extensions, etc.)
+
+## Rules that held up in practice
+
+- `switch_tab()` is **not enough** if the user expects Chrome to visibly change.
+- `Target.activateTarget` is the CDP-side "show this tab".
+- `list_tabs()` includes `chrome://newtab/` by default; ask for `include_chrome=False` when you want only real pages.
+- `chrome://omnibox-popup.top-chrome/` can appear as a fake page target; ignore it for user-facing tab lists.
+- If a page has `w=0 h=0`, you may be attached to the wrong target or a non-window surface.
+- For dynamic UIs, re-read element rects after opening dropdowns / modals before coordinate-clicking.
