reaatech/prompt-version-control

These packages give you Git-like version control for AI prompts — an API server, TypeScript SDK, CLI, and MCP server that let you track prompt changes, gate promotions on eval results, and serve A/B deployments. You'd adopt them to solve the problem of managing prompt iterations across development, staging, and production without manual copy-pasting or ad-hoc versioning. The most distinctive thing is that the entire lifecycle — from creating a draft to promoting it to production — is gated by evaluation harness results, with AI agents able to pull managed prompts at runtime via the MCP server.
