AI Security Review
scanned 1mo ago · by lpm-firewall-aiThe lifecycle behavior is package-aligned native CLI setup and is limited to the package's own launcher. 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 credential collection, exfiltration, persistence, or writes outside the package were found.
Mechanism
It locates or downloads the matching platform binary and links the package's bin/droid shim to it.
AI rationale
The lifecycle behavior is package-aligned native CLI setup and is limited to the package's own launcher. Static inspection found no concrete malicious behavior.

Decision evidence
public snapshotAI called this Clean at 90.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision

- The installer falls back to downloading the selected platform binary only when its optional dependency is absent.
- The installer replaces its own droid shim with a link to that binary.
