To solve this, teams employ various methods based on their operational maturity. The options range from using environment variables to implementing a dedicated prompt registry service. Environment variables and database columns provide basic decoupling and versioning but lack testing capabilities and have size limitations. Feature flag services offer more robust features like rollouts, audit logs, and staging separation but are not designed for prompt content. The ideal solution is a dedicated prompt registry service, which provides a UI for authoring and testing prompts, proper versioning, and enterprise-grade delivery infrastructure.",

Now you're waiting 12 minutes for CI to run, watching a deploy pipeline you've watched a thousand times, so that a customer-facing chatbot can say \"assist\" instead of \"help\".
