Mervin

About This Project

Mervin puts a language model in your Unix pipes. Pipe text in; it sends that text to a model on OpenRouter and streams the answer back to stdout. It is quiet by default: only the model’s reply is printed, so it composes with everything else on the command line.

Four commands cover the common jobs. diagnose explains errors and logs, and leads with the most likely cause. review critiques a diff and flags bugs and security issues. summarize condenses long text. run takes any free-text instruction when no specialized command fits. usage adds up what past calls cost, from a log kept on your machine.
