Factory Droid CLI - AI-powered software engineering agent
AI Security Review
scanned 19d ago · by lpm-firewall-aiThe lifecycle hook and native binary download are consistent with installing this CLI's version-matched platform executable. Source inspection found no concrete attack behavior.
Static reason
One or more suspicious static signals were detected.
Trigger
Package installation runs the postinstall hook; its download fallback activates only if the optional platform binary is unavailable.
Impact
This provides the package's command-line executable; the inspected source establishes no unrelated collection or destructive behavior.
Mechanism
The fallback retrieves the selected platform package from the npm registry, extracts its binary, and links the binary to the command shim.
AI rationale
The lifecycle hook and native binary download are consistent with installing this CLI's version-matched platform executable. Source inspection found no concrete attack behavior.

Decision evidence
public snapshotAI called this Clean at 88.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The postinstall hook is declared alongside optional platform packages pinned to this release.
- The installer fetches platform package metadata from the npm registry and uses its tarball URL.
- The download fallback runs only when the optional platform binary is missing, then writes the extracted binary locally and links it to the command shim.
