@linzumi/cli@1.0.239
Linzumi CLI — point a Codex agent at the real code on your laptop, with your team watching and steering from shared threads.
AI Security Review
scanned 2mo ago · by lpm-firewall-aiThe package has material remote-execution, tunneling, and persistence capabilities, so it warrants a warning. The absence of install-time execution and the explicit command triggers do not support a malicious-install verdict.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
A user runs the cloud runner, connect, or service install command.
Impact
A user who authorizes these commands can expose local services or create a long-running agent runner.
Mechanism
Configured process launching, authenticated TCP forwarding, and systemd persistence.
AI rationale
The package has material remote-execution, tunneling, and persistence capabilities, so it warrants a warning. The absence of install-time execution and the explicit command triggers do not support a malicious-install verdict.

Decision evidence
public snapshotAI called this Suspicious at 84.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The package installs a CLI intended to control Codex agents from shared threads.
- The cloud supervisor embeds a wrapper that starts a command and arguments supplied through its runtime configuration.
- The connect command opens a loopback listener for a registered, externally published TCP forward.
- An explicit service command writes a restart-always systemd unit, creating persistent execution when invoked.
Evidence against
- package.json has no preinstall, install, or postinstall lifecycle hook.
- The risky network, tunnel, service, and process features are exposed through explicit CLI commands rather than automatic package installation.
- The vendoring script is a development command for OpenAI protocol declarations, not an install hook.
