droid@0.218.0
Factory Droid CLI - AI-powered software engineering agent
AI Security Review
scanned 2mo ago · by lpm-firewall-aiThis is a transparent native-CLI installer with package-local writes and a registry fallback, not a concrete malicious chain. The lifecycle and remote binary retrieval are supply-chain risk primitives but are aligned with the CLI’s stated packaging structure.
Static reason
One or more suspicious static signals were detected.
Trigger
npm postinstall, only when the platform optional dependency is unavailable.
Impact
A native CLI binary is placed or linked within this package’s bin directory; no credential exfiltration or external configuration mutation was found.
Mechanism
Platform binary fallback download and local command-shim linking.
AI rationale
This is a transparent native-CLI installer with package-local writes and a registry fallback, not a concrete malicious chain. The lifecycle and remote binary retrieval are supply-chain risk primitives but are aligned with the CLI’s stated packaging structure.
Evidence
bin/droidbin/droid.backupbin/droid.exe
Decision evidence
public snapshotAI called this Clean at 91.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The postinstall hook downloads a platform binary when its optional dependency is unavailable.
- The hook writes and links only the package’s own bin/droid path.
Evidence against
- The manifest pins platform-specific optional dependencies to the same release.
- Network access is limited to retrieving the selected platform package from the npm registry.
- The npm token is attached only to npmjs.org requests; no other credential collection or upload is present.
- No self-dependency, broad project mutation, persistence, or agent-control configuration writes were found.

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.
