Eirikur, only worry about implementing the adapter and Task.Tools methods for this feature. Once those are in place, we'll add the announcement as appropriate to the DefaultPerk.

Let's try to get this patch done by next Wednesday. Here's a more complete spec of the methods to be implemented:

getAccActionNames()
# returns names of all actions in the Action interface
# raises NotImplementedError if the Action interface isn't supported
# should be added to the default info adapter

getAccActionDescriptions()
# returns descriptions of all actions in the Action interface
# raises NotImplementedError if the Action interface isn't supported
# should be added to the default info adapter

getAccActionCount()
# returns the total number of actions available in the Action interface
# raises NotImplementedError if the Action interface isn't supported
# should be added to the default info adapter

getAccActionKeys()
# returns the key bindings of all actions in the Action interface
# multiple key bindings may be assigned to a single action and are returned by at-spi as strings like so: c;Alt-v:c;F11
# the string key binding for a single action should be split on the ; character and returned as a list (in other words, this method returns a list of lists)
# raises NotImplementedError if the Action interface isn't supported
# should be added to the default info adapter

doAccAction(*indices)
# performs all of the actions at the indices given in sequence using the Action interface
# raises NotImplementedError if the Action interface isn't supported
# should be added to the default action adapter

Fixed in the development version. The fix will be available in the next major release. Thank you for your bug report.
