·2 views

This is a submission for the Hacktoberfest Weekend Challenge: Build for a Friend It was 1:45 AM on a Tuesday. My friend Ayush was sitting across from me, rubbing his temples in exhaustion in front of a blank screen. He had spent hours trying to re-architect an event-driven system, only to slam his laptop shut and vent: "I know I’ve already thought about this.

Most AI tools hand over the answer, and my friend ended up copy-pasting code without understanding it. Byte-Gemma is a fine-tuned Gemma 3 1B that teaches Socratically. It stays under ~100 words, praises one thing you got right, and asks one guiding question. It runs locally on Android, so it works without internet or an API bill.

I built gedik, a security-audit skill for Claude Code. Before telling anyone it was good, I wanted a number. So on 30 September 2026 I ran it against three other tools on two targets, with the answer key kept outside every run directory. Then I put the results in the README, including the parts where it lost. This post is about those parts.
