Is there a reason why you want to prefix with accessibility_? Why not
'autoclick'?

I was thinking to make it clear that this service is part of the accessibility
services (forgot to update touch_hud). What do you think? 

   sources = [
     "main.cc",
   ]
 
   deps = [
     ":lib",
     "//base",
     "//mojo/public/cpp/bindings",
     "//services/shell/public/cpp",
     "//services/shell/public/cpp:sources",
     "//ui/views/mus:for_mojo_application",
   ]
 
   resources = [ "$root_out_dir/views_mus_resources.pak" ]
 
   data_deps = [
     ":manifest",
   ]
 }
 
 service_manifest("manifest") {
-  name = "touch_hud"
+  name = "accessibility_autoclick"
   source = "manifest.json"
 }
