9r3i/apk-builder ? reverse-engineered prompt

Build me a simple APK builder tool for AI users that can extract an Android app from an APK, rebuild it after changes, and sign the finished file so it can be installed again.

I want it to feel like a small command line helper with commands like extract, build, sign, and a prepare then execute flow using a config file. It should be easy to install as a package, and it should work with the usual APK tooling under the hood. If you need to check current docs for any APK or signing details, go ahead and look them up online.

Make the experience straightforward, with clear output and helpful errors when something goes wrong. The main goal is to let someone point at an APK or a folder and have the tool do the right thing without needing to know the low level steps.
