Zach Ahn has developed a tool called Vomit that converts Claude 5's token vomit into readable English by piping it through a local LLM. The tool is fully local with no telemetry or external dependencies, though it currently only supports Mac and may produce some hallucinations since the local LLM can only see what Claude communicates. After installation via `go install github.com/zachahn/vomit@latest`, users run `vomit init` to set up connection details to their preferred local LLM.

The tool supports several modes including `vomit scrub -claude` for replacing Claude's output via hooks, and a non-invasive mode using `vomit list` and `vomit tail` commands. It works with Llama.app, Ollama, and anything using the OpenAI API. The project is licensed under GNU GPLv3 and is described as vibe-coded with limited testing.
