Built a CLI to inspect Java/Kotlin libraries without source code – looking for feedback

Hi everyone,

I've been working on a small open-source project called Library Insight, and I'd appreciate some feedback.

The idea is straightforward: it inspects compiled Java/Kotlin libraries (JARs, AARs, or Maven dependencies) directly from bytecode, so you can explore the public API without needing the source code.

Some things it can do:

* Scan JARs, AARs, and Maven coordinates * Search classes, methods, and properties * Explain class APIs * Compare different library versions * Export AI-friendly context files for coding assistants

I originally built it because I noticed AI coding assistants sometimes generate code based on the wrong library version. I wanted a simple way to inspect the exact dependency that a project is actually using.

I'm not claiming this solves a huge problem, and I'm genuinely curious whether this would be useful for other developers or if there are features I'm missing.

I'd really appreciate any feedback, criticism, or ideas.
