free-anthropic-claude@5.3.0

Analysis

free-anthropic-claude is a combosquat package impersonating the Anthropic Claude SDK. It declares a postinstall lifecycle hook (scripts.postinstall = "node cli.js") that executes automatically on npm install. The package's index.js spawns a Python child process with the detached flag (cp.spawn(python, [pyPath], { detached: true })), creating a background process that persists independently of the parent npm process. The package has no repository and provides no legitimate SDK functionality — its sole purpose is to execute code at install time and spawn a persistent child process.
