The tools was mostly already known, no? (I wish they had a "present" tool which allowed to model to copy-paste from files/context/etc. showing the user some content without forcing it through the model)

Yeah in fact one thing claude is freaking great at is decompilation.

If you can download it client side you can likely place a copy in a folder and ask claude

‘decompile the app in this folder to answer further questions on how it works. As an an example first question explain what happens when a user does X’.

I do this with obscure video games where i want to a guide on how some mechanics work. Eg. https://pastes.io/jagged-all-69136 as a result of a session.

It can ruin some games but despite the possibility of hallucinations i find it waaay more reliable than random internet answers.

Works for apps too. Obfuscation doesn’t seem to stop it.
