Issue Explainer: a local Gemma tool that turns GitHub issues into a plan (built for me)

What I Built

This one is for me. I'm a third-year student making my first
open-source contributions, and the hardest part isn't the code, it's
understanding an issue well enough to start.

Issue Explainer: paste a GitHub issue link and get a summary,
type, difficulty (based on my own skills), skills needed, where to
look in the repo, first 3 steps, and one question to ask the
maintainer. It also warns me if the model names a file that doesn't
exist in the repo.

I tested it on a real issue I wanted to understand: https://github.com/agentrhq/webcmd/issues/534.

Demo

It runs locally, so there is no deployed link. Setup steps are in the
README.

How I Built It

Model: Gemma (gemma3:4b) running locally through Ollama
Also compared: qwen2.5:3b and qwen2.5:7b (dropdown in the UI)
App: Python, GitHub REST API, Streamlit UI plus a CLI
Safety check: the app compares the files the model suggests against the repo's real file tree

One function, explain(), does the work. The CLI and the UI both
call it.

Why Does Open Innovation Matter?

Cost: no API bill, so I can analyze as many issues as I like.
Swappable: I changed models from a dropdown and compared them on the same issue: [your times and one quality note].
Local: the model step ran with Wi-Fi off: [yes or no, after you test it].
Honest limits: my first run took 332 seconds on a laptop, and "Where to look" sometimes points to docs instead of code. [Your fix, if any.]
