Beyond Prompts: How Git Hooks Steer AI Coding...

TLDR: At Fleek, both engineers and non-engineers build internal tools using AI coding agents. We found that instruction files alone aren't enough - the AI follows them most of the time, but not always. Git hooks gave us a deterministic enforcement layer on top. This post walks through how we designed them and why the error messages matter more than you think. The Problem We run an internal tools platform - a monorepo with 10+ sub-applications.
