Research direction
Start at the task decorator in invoke.tasks and Collection.add_task in invoke.collection, using the example in the issue to reproduce the mypy error. Trace the declared types for the decorated function and add_task; the work is done when mypy accepts ns.add_task(foo) without the reported argument-type error.

Description
from invoke.tasks import task
from invoke.collection import Collection
@task
def foo(ctx):
pass
ns = Collection()
ns.add_task(foo)
leads to an mypy error:
error: Argument 1 to "add_task" of "Collection" has incompatible type "Callable[..., Any]"; expected "Task[Any]" [arg-type]
ns.add_task(foo)
