If this package is installed
Remove it, treat the machine (or CI runner) as compromised, and rotate every secret, token and key it could access — from a different, clean machine.

On npm install, the package's postinstall script collects host identifiers (os.hostname(), platform, arch, Node version, and package/lifecycle metadata) and POSTs them via https.request to the hardcoded endpoint https://onpx9s3x.instances.poc.jchunt.top/gemini-cli-a2a-server. The package name mimics a private Google Gemini CLI a2a-server component, and a source.txt reference in the tarball points at that internal package — consistent with a dependency-confusion probe that pings out from any environment that inadvertently resolves this public name instead of the intended private one.
