Given it's not something that needs to be done as frequently as most other Android dev tasks, I'd write a separate skill for this, or even a plugin.

ok, i have pulled it out as a separate skill because i think this will be a very common task (whenever someone is investigating a crash) and I want it to be as discoverable as possible.
i tested that claude could find it without using the word 'retrace'
very side note, but i wondered if the android skill should be renamed to android-dev or something, as android itself is a very broad church encompassing most aspects of my job 😅
just a thought
