Hi HN, I m Yousef. I ve built a lot of agents for vertical AI startups in the past few years, and I ve become convinced that prompts are code, so must be kept in git.The startups that decouple do so because engineers build agents with git, and non-engineers (lawyers/clinicians/etc) align agents outside of git.So the problem of coordination and versioning shifts to out-of-sync docs and platforms.This is why I built Gravel.An open-source library that embeds a prompt editor straight into your app. Your prompts have a single source of truth (your codebase).After a minute of setup:1. Your team can make prompt PRs without knowing what a PR is2. They can review outputs straight from your production traces3. Those reviews create prompt change suggestions and evalsIf you re building vertical agents, would love your feedback on it!
