droid@0.229.0
Factory Droid CLI - AI-powered software engineering agent
AI Security Review
scanned 1mo ago · by lpm-firewall-aiStatic inspection found package-aligned binary installation and command dispatch only. No concrete malicious behavior was identified.
Static reason
One or more suspicious static signals were detected.
Trigger
Package installation runs the declared postinstall script; command execution runs the droid shim.
Impact
No confirmed credential exfiltration, persistence, foreign configuration mutation, or destructive behavior was established.
Mechanism
The installer may request a platform package from the npm registry and creates a hard link to it within the package directory.
AI rationale
Static inspection found package-aligned binary installation and command dispatch only. No concrete malicious behavior was identified.

Decision evidence
public snapshotAI called this Clean at 91.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The package declares only a postinstall entry that runs install.js.
- The installer fetches a fixed-version platform binary from the npm registry only when its optional dependency is unavailable.
- The installer replaces its own droid shim with a link to the selected binary.
- The NPM token header is conditionally limited to npmjs.org hosts.
- The command shim forwards user arguments to the selected platform binary.
