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 is

2. They can review outputs straight from your production traces

3. Those reviews create prompt change suggestions and evals

If you're building vertical agents, would love your feedback on it!
