List npm Package Content

This skill lists the exact contents of an npm package tarball - the same files that would be uploaded to npm and downloaded by users.

Usage

Run the script from the package directory (e.g., `packages/ai`):

bash scripts/list-package-files.sh

The script will build the package, create a tarball, list its contents, and clean up automatically.

Understanding Package Contents

The files included are determined by:

1. **`files` field in `package.json`** - explicit allowlist of files/directories 2. **`.npmignore`** - files to exclude (if present) 3. **`.gitignore`** - used if no `.npmignore` exists 4. **Always included**: `package.json`, `README`, `LICENSE`, `CHANGELOG` 5. **Always excluded**: `.git`, `node_modules`, `.npmrc`, etc.
