+Can we validate prompts in CI before deploy?
+Yes. Use the CLI validate and compile commands in your CI pipeline to catch issues before release.
+Is PromptOpsKit open source?
+Yes. The project is MIT-licensed and maintained in a public GitHub repository.
+Open source and production-ready defaults
++ PromptOpsKit is MIT-licensed and designed for teams that need testable prompt operations. + Use source prompts in development and pre-compiled artifacts in production for speed and reliability. +
