 | `--timeout` | Wait timeout in seconds (default: 120) |
-| `--new` | Start a new chat session (default: false) |

+## Behavior
+
+- `opencli grok ask` keeps the upstream/default behavior intact.
+- `opencli grok ask --web` switches to the newer hardened consumer-web implementation.
+- The `--web` path adds stricter composer detection, clearer blocked/session-gated hints, and waits for a stabilized assistant bubble before returning.
 
 ## Prerequisites
 
-- Chrome running and **logged into** grok.com
+- The Grok adapter still depends on browser-backed access to `grok.com`
+- For `--web`, Chrome should already be running with an authenticated Grok consumer session
 - [Browser Bridge extension](/guide/browser-bridge) installed
+
+## Caveats
+
+- `--web` drives the Grok consumer web UI in the browser, not an API.
+- It depends on an already-authenticated session and can fail if Grok shows login, challenge, rate-limit, or other session-gating UI.
+- It may break when the Grok composer DOM, submit button behavior, or message bubble structure changes.
