Factory Droid CLI - AI-powered software engineering agent
AI Security Review
scanned 1mo ago · by lpm-firewall-aiThe install script is the usual optional-binary fallback: it fetches the pinned @factory platform tarball from the npm registry and links it inside this package. Credential use, shell checks, and file writes stay aligned with that installer and do not show exfiltration or agent-control mutation.
Static reason
One or more suspicious static signals were detected.
Trigger
npm postinstall runs node install.js after install.
Impact
Install changes stay inside the installed package and do not mutate foreign agent configuration, harvest secrets, or send credentials to an unrelated host.
Mechanism
The script resolves a same-vendor platform package, writes its binary into this package bin directory, and hard-links the droid shim to it. Registry authentication is limited to npmjs.org hosts.
AI rationale
The install script is the usual optional-binary fallback: it fetches the pinned @factory platform tarball from the npm registry and links it inside this package. Credential use, shell checks, and file writes stay aligned with that installer and do not show exfiltration or agent-control mutation.
Decision evidence
public snapshotAI called this Clean at 86.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- postinstall only runs node install.js; optionalDependencies are same-version @factory platform packages, not this package name.
- If the platform binary is missing, install.js requests that package packument from registry.npmjs.org and downloads the returned tarball.
- The extracted binary is written only under this package bin directory with mode 0o755.
- NPM_TOKEN is added as a Bearer header only when the request hostname includes npmjs.org.
- On Unix the postinstall replaces bin/droid with a hard link to that binary; the PATH check only prints a shell hint and does not edit profile files.
Evidence against
- Redirect responses are followed without a second host allowlist, though the token header is rechecked on each URL.
- The native droid binary is supplied by optional platform packages and is not present in this package, so its runtime behavior cannot be inspected here.

Install-time code downloads an unverified remote native executable, stages it locally, activates an executable path, and exposes it to process execution.
