completion-kit 0.1.0.rc1

CompletionKit is a mountable Rails engine for rigorous prompt testing: run prompts against datasets, score outputs with an LLM-as-judge against custom metrics and rubrics, track versions, and iterate with AI-assisted improvement suggestions. Every resource is accessible through a bearer-token REST API and a built-in Model Context Protocol server, so you can drive it from a browser, from HTTP clients, or directly from agents like Claude Code.
