Factory Droid CLI - AI-powered software engineering agent
AI Security Review
scanned 22d ago · by lpm-firewall-aiThe lifecycle script installs a version-matched platform binary for this CLI and links the command shim to it. The inspected source supports ordinary package setup, not malicious behavior.
Static reason
One or more suspicious static signals were detected.
Trigger
Package installation runs the postinstall script.
Impact
This sets up the droid command; the inspected source does not establish an unrelated attack surface.
Mechanism
The script requests the selected companion package from npm’s registry, extracts its expected executable, and links the CLI shim to it.
AI rationale
The lifecycle script installs a version-matched platform binary for this CLI and links the command shim to it. The inspected source supports ordinary package setup, not malicious behavior.

Decision evidence
public snapshotAI called this Clean at 94.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- package.json runs install.js as postinstall and declares version-matched platform binary dependencies.
- install.js queries registry.npmjs.org for the selected platform package’s tarball.
- install.js extracts only the expected platform executable and writes it under this package’s bin directory.
- install.js links the local droid shim to the binary and validates the installed binary version.
- NPM_TOKEN is added only for requests whose hostname includes npmjs.org.
