Factory Droid CLI - AI-powered software engineering agent
AI Security Review
scanned 21d ago · by lpm-firewall-aiThe postinstall download and executable write are package-aligned setup for the declared platform-specific CLI dependencies. Although this fallback does not verify a tarball integrity value in the inspected code, no concrete attack behavior was established.
Static reason
One or more suspicious static signals were detected.
Trigger
Package installation runs the postinstall script; its download fallback runs only when the platform binary cannot be resolved.
Impact
This supplies the CLI binary and optimizes its launcher; inspected source did not establish malicious behavior.
Mechanism
The installer requests npm release metadata for the selected platform package, extracts its expected binary, and places it in the local bin directory.
AI rationale
The postinstall download and executable write are package-aligned setup for the declared platform-specific CLI dependencies. Although this fallback does not verify a tarball integrity value in the inspected code, no concrete attack behavior was established.

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 install.js after installation and declares matching-version platform binaries as optional dependencies.
- If an optional binary is missing, install.js selects a platform package and retrieves its release metadata from the npm registry.
- The fallback extracts the expected platform binary from the package tarball and writes it to the local bin directory.
- The installer links the binary to the command shim when optimization is supported.
Evidence against
- The postinstall fallback downloads and installs an executable without checking the tarball against an integrity value in this code.

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.
