satyam-narayan/rn-size-analyzer ? reverse-engineered prompt

Build me a React Native size analyzer I can run from the root of an app. I want it to inspect both Android and iOS, look for things that make the app big, and generate a local HTML report I can open in the browser. It should be able to detect an APK, AAB, or IPA if one is already in the project, and if not, still analyze the app config, dependencies, assets, and build settings.

The report should clearly explain the main issues in plain language, with evidence, impact, and a recommendation for each one. I’d like a summary view with scores or ratings, plus a list of the biggest problems and what to fix first. If possible, include a JSON output too for CI use, and make sure the report is saved locally in a folder like rn size report. If you need to, look up current docs online for React Native, Android, and iOS project formats.
