@reason-machines/cli-darwin-x64@0.2.460: Manual Review npm

AI Security Review

scanned 3d ago · by lpm-firewall-ai

The manifest has no install lifecycle scripts, and the inspected runtime excerpt shows agent configuration paths among protected paths. The main native executable’s behavior remains materially unresolved, so the source evidence does not support a clean or malicious verdict.

Static reason

One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review

Trigger

Running the packaged bin/reason executable.

Impact

The executable’s effects cannot be determined from the available inspection.

Mechanism

The available analysis does not establish loader reachability or account for all native behavior.

AI rationale

The manifest has no install lifecycle scripts, and the inspected runtime excerpt shows agent configuration paths among protected paths. The main native executable’s behavior remains materially unresolved, so the source evidence does not support a clean or malicious verdict.

Evidence

.lpm-inspection-U47rgz/0-c6166ba60af8.txtbin/reason

Decision evidence

public snapshot

AI called this Manual Review at 87.0% confidence as Unknown with medium false-positive risk.

AI review observations

The verified offline analysis identifies bin/reason as a 78 MB Mach-O executable, but its bounded embedded-source windows cannot establish what code runs or exclude other native behavior.
The inspected runtime bundle includes protected agent configuration paths such as .mcp.json and .claude/commands; this does not resolve the native executable’s behavior.

Evidence against

package.json contains no lifecycle scripts and describes a darwin-x64 native CLI package.
