 "title": "Shorten Claude Code output with a local LLM",
 "page_title": "How to shorten Claude Code output with a local LLM with Vomit",
 "summary": "Hook Vomit into Claude Code so a local model rewrites its verbose replies in plain English.",
 "who": "A developer using Claude Code who wants to save tokens and read shorter replies, and has a local LLM server running.",
 "problem": "Claude Code's output is often long and token-heavy, and the developer wants it condensed without sending it to another hosted service.",
 "outcome": "Claude Code's replies in the terminal are rewritten by a local model, and the original output is still available with ctrl-o.",
 "steps": [
  "Install Llama.app from https://github.com/ggml-org/Llama-macOS, then download GPT-OSS 20B through it (the README's recommended model).",
  "Run `go install github.com/zachahn/vomit@latest`.",
  "Run `vomit init` to set up the connection details to your LLM.",
  "Run `vomit scrub -claude` and follow its instructions on replacing Claude's output via hooks.",
  "Start Claude Code and send a prompt. Press ctrl-o to compare with Claude's original output."
 ],
 "agent_prompt": "Install the zachahn/vomit repo with `go install github.com/zachahn/vomit@latest`, then run `vomit init` against the local LLM server at <llm-endpoint> and follow the output of `vomit scrub -claude` to wire up the Claude Code hook. Report the setup steps you completed, and verify by sending one Claude Code prompt and confirming the reply is rewritten, with the original visible after ctrl-o.",
