Factory Droid CLI - AI-powered software engineering agent
AI Security Review
scanned 27d ago · by lpm-firewall-aiThe postinstall activity is consistent with installing this CLI's matching platform binary and optimizing its command shim. Source inspection found no concrete attack behavior, so the scanner's install and network signals do not warrant a warning or block.
Static reason
One or more suspicious static signals were detected.
Trigger
Package installation runs the postinstall script; the download fallback activates when the optional platform binary is unavailable.
Impact
The inspected behavior installs and selects the CLI binary; no concrete malicious effect was established.
Mechanism
The installer fetches the selected platform package's tarball, extracts its binary into this package's bin directory, checks its version, and links it to the command shim.

Decision evidence
public snapshotAI called this Clean at 90.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The manifest runs a postinstall script and pins optional platform binaries to the same version under the @factory scope.
- The installer downloads the selected platform package from npm only as a fallback when the optional binary is unavailable, then writes its binary into this package's bin directory.
- The installer replaces the package's command shim with a link to that binary and includes a fallback that restores the shim if linking fails.
Evidence against
- The postinstall downloads and runs a native binary during installation, but the inspected code ties the fallback to the matching platform package and version from npm.
- The code can forward NPM_TOKEN to hosts whose names contain npmjs.org and follows redirects; no malicious destination or credential exfiltration behavior was established in the inspected flow.

Install Time Lifecycle Scripts
Package defines install-time lifecycle scripts.

Install-time code downloads an unverified remote native executable, stages it locally, activates an executable path, and exposes it to process execution.

Unverified Remote Native Payload Install
Install-time source downloads a native archive from a fixed external host without transport verification, extracts it, and installs an executable payload.
