How are you letting non-engineer teammates edit prompts in production?

I build vertical agents for legal and clinical workflows. The same coordination problem keeps bugging me: The subject matter expert (the lawyer, the clinician) is the only person who actually knows what the prompt should say, but I'm the only person who can ship code. What I've tried: 1. Lifting prompts into a hosted platform (Langfuse / PromptLayer / a homemade admin panel). Works until you realise the prompt is now decoupled from the code that calls it, and their edits race your deploys. 2. Have them edit prompts in Google Docs and I copy their edits into the codebase. Works but still messy on coordination and versioning. 3. Giving them a GitHub account but they struggle to use git. Curious what others have landed on, especially anyone shipping agents into a regulated domain where the SME has to sign off on every prompt change. I ended up building a library for it which mounts a prompt editor within the app, and uses GitHub as a backend, so prompts can stay on git, and SMEs can open PRs without knowing what a PR is. Happy to share the link if it's useful but mostly want to hear what's working for people.
