@@ -189,10 +189,26 @@ All existing endpoints accept optional `?profile=<name>` query parameter:
 - `GET /?profile=work` — status for work profile
 - `POST /start?profile=work` — start work profile browser
 - `GET /tabs?profile=work` — list tabs for work profile
+- `POST /tabs/open?profile=work` — open tab in work profile
 - etc.
 
 When `profile` is omitted, uses `browser.defaultProfile` (defaults to "clawd").
 
+### Agent browser tool
+
+The `browser` tool accepts an optional `profile` parameter for all actions:
+
+```json
+{
+  "action": "open",
+  "targetUrl": "https://example.com",
+  "profile": "work"
+}
+```
+
+This routes the operation to the specified profile's browser instance. Omitting
+`profile` uses the default profile.
+
 ### Profile naming rules
 
 - Lowercase alphanumeric characters and hyphens only
