Factory Droid CLI - AI-powered software engineering agent
AI Security Review
scanned 2mo ago · by lpm-firewall-aiThe lifecycle behavior is a package-aligned native CLI bootstrap, with a fixed same-version platform-package mapping and package-local file changes. The registry fallback and token forwarding warrant normal supply-chain caution, but the inspected source provides no concrete malicious behavior.
Static reason
One or more suspicious static signals were detected.
Trigger
npm installation with lifecycle scripts enabled and no resolved platform optional dependency
Impact
A native executable from the matching platform package can be written and used as this CLI's droid command.
Mechanism
Registry fallback download and package-local binary shim linking

Decision evidence
public snapshotAI called this Clean at 88.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- A postinstall hook runs install.js automatically.
- If its platform optional dependency is unavailable, the hook downloads that platform package from the npm registry and writes its native executable.
- The fallback may send NPM_TOKEN as registry authentication and follows HTTP redirects.
Evidence against
- The requested platform package and version are derived from this package's fixed same-version optional-dependency mapping.
- The installer changes only its own bin/droid shim into a link to the selected platform binary.
- No source code harvests files, modifies agent configuration, establishes persistence, or exfiltrates data to a non-registry endpoint.

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.
