Installation

lmpack needs Node.js 22.12 or later. Check with node --version.

Run without installing

npx lmpack pack --dry-run

npx downloads the package on first use and caches it.

Install globally

npm install --global lmpack
lmpack --version

Install in a project

Useful when a project pins the version or runs lmpack in CI.

npm install --save-dev lmpack

Then call it from a script in package.json:

{
  "scripts": {
    "pack:llm": "lmpack pack --profile backend --out pack.md"
  }
}

Git

--git-diff runs the local git executable. Everything else works without git, including .gitignore handling.

Network

lmpack makes no network requests. Tokenizers ship inside the package, there is no telemetry and no update check.
