CommitQuiz Pre-commit Hook

Quiz yourself on your own diff before git commit to verify you understand your changes

Problem

Developers often commit code they do not fully understand, making it hard to explain or debug later. Existing code review tools focus on style and errors, not the author's grasp of the change.

Solution

Run as a pre-commit hook, analyze the diff and generate a few targeted multiple-choice or short-answer questions; the developer must answer correctly to commit, otherwise they get hints to review relevant code or docs.

Users

Engineers who care about code quality, tech leads, programming learners

MVP

Parse git diff and extract key change points; auto-generate 2-3 multiple-choice questions; interactive terminal quiz; pass to allow commit, fail to block with hints; configurable skip

Revenue

Free open-source core hook; paid team dashboard, custom difficulty, and knowledge gap reports

Why now

As AI-generated code rises, developers' understanding of their own commits declines. A lightweight quiz to force review is a novel and low-cost quality safeguard.
