Factory Droid CLI - AI-powered software engineering agent
AI Security Review
scanned 1mo ago · by lpm-firewall-aiThe automatic installer is package-aligned binary setup and its network fallback targets the npm registry. Static inspection found no concrete malicious behavior.
Static reason
One or more suspicious static signals were detected.
Trigger
npm runs the postinstall hook.
Impact
No confirmed credential theft, external control-surface mutation, persistence, or destructive behavior was found.
Mechanism
The installer resolves a platform binary, optionally obtains its package from the npm registry, and links it to the package command shim.
AI rationale
The automatic installer is package-aligned binary setup and its network fallback targets the npm registry. Static inspection found no concrete malicious behavior.

- The fallback queries the npm registry for the selected platform package.
- The installer replaces its own command shim with a link to the resolved platform binary.
