Git Interviewer
A pre-commit hook that interviews you about your code before letting you commit.
01The problem
Most developers commit too quickly, without thinking about design decisions, intent or tradeoffs. Git Interviewer turns every commit into a lightweight technical interview, like having a senior engineer inside your terminal.
02What I built
Pick who's grilling you:
01
Nice
Supportive engineer who wants clarity and understanding.
02
Grumpy
Tired senior dev who has seen too much. Very picky.
03
Systems
Asks about architecture, scaling, risk and tradeoffs.
04
Founder
Focuses on product impact and iteration speed.
03Architecture
Written in Python and wired into Git hooks to intercept the commit. It analyzes the diff of staged files and uses an LLM to generate context-aware questions for the chosen persona.
It runs the interaction loop in the terminal and validates the answers before letting the commit proceed, or rejects it if the explanation is thin. Validating the thought process before code lands means better engineering discipline across a team.
04Challenges & lessons
Built during a snow delay
I got to the airport comically early for a winter-break flight, then it was delayed by heavy snow in Boston. I had time to kill.
Shipping a CLI is easier than it looks
I came out with a much deeper understanding of git and git workflows, and did a lot of reflecting on my own habits. Packaging it for others on PyPI was surprisingly easy. I plan to make it a lot better, and a lot more annoying to use.
