I have prompted the Claude code to launch sub-tasks and let them run in parallel, which could be helpful when, for example, we use the Claude code to translate an Android package to iOS.

Here is an example prompt:

The TODOs looks good, divide them into subtasks and run them in parallel.

The Claude code will launch sub-tasks like the following, and report the amount of tokens used by each sub-task for me (>100k tokens in total):

But it seems that the ccusage did not capture tokens used by these sub-tasks (only 69k reported for the block):

It would be awesome if these tokens were burned by sub-tasks as well, thanks in advance.
