@linzumi/cli@1.0.259
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-aiThis is not a confirmed malicious install chain because there are no package lifecycle hooks. The explicit relay and dynamic compilation capabilities leave a meaningful, unresolved runtime risk.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
A user runs the tcpConnect CLI command or another cloud/agent command.
Impact
A user who invokes these features can expose local network traffic to the configured service; the bundled compilation increases review risk.
Mechanism
Local TCP-to-WebSocket relay and bundled dynamic compilation.
AI rationale
This is not a confirmed malicious install chain because there are no package lifecycle hooks. The explicit relay and dynamic compilation capabilities leave a meaningful, unresolved runtime risk.

Decision evidence
public snapshotAI called this Suspicious at 78.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The CLI dispatches an explicit tcpConnect command into a TCP relay module.
- The relay module creates a local server and sends binary frames over a tunnel WebSocket.
- The shipped cloud-supervisor bundle dynamically compiles generated JavaScript.
- A development-only vendor script can clone a configurable Git source and run local tooling when explicitly invoked.
Evidence against
- package.json has no preinstall, install, postinstall, or prepare lifecycle hook.
- The risky networking and process features are reached through explicit CLI or development-script commands, not package installation.
