droid@0.226.1
Factory Droid CLI - AI-powered software engineering agent
AI Security Review
scanned 1mo ago · by lpm-firewall-aiThe postinstall behavior is a package-aligned native CLI setup path with pinned platform packages and package-local file changes. Static inspection found no concrete malicious behavior.
Static reason
One or more suspicious static signals were detected.
Trigger
npm postinstall runs install.js.
Impact
No confirmed malicious impact was established; changes are limited to this package's bin path.
Mechanism
It obtains the matching Factory platform binary when the optional dependency is absent, then links the local droid shim to that binary.
AI rationale
The postinstall behavior is a package-aligned native CLI setup path with pinned platform packages and package-local file changes. Static inspection found no concrete 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
- The package declares a postinstall hook and version-pinned Factory platform optional dependencies.
- The installer selects the platform package and retrieves its tarball through the npm registry fallback.
- The installer extracts only the expected platform binary and replaces this package's droid shim with a link to it.
- No credential harvesting, foreign configuration mutation, destructive action, or untrusted command execution was identified in the inspected sources.
