Factory Droid CLI - AI-powered software engineering agent
AI Security Review
scanned 1mo ago · by lpm-firewall-aiThe postinstall behavior is a package-local binary shim for the Factory Droid CLI, with registry downloads limited to the matching platform package and the npm token bound to npmjs.org hosts. No credential harvesting, agent-control writes, or self-install chain appears in the inspected sources.
Static reason
One or more suspicious static signals were detected.
Trigger
npm postinstall runs node install.js after the package is installed.
Impact
The installed droid command runs the packaged native binary. No foreign agent config, credential export, or consumer-project mutation was found.
Mechanism
The script resolves a same-version @factory platform binary, optionally downloads its tarball from registry.npmjs.org, writes it under the package bin directory, and hardlinks the local shim.
AI rationale
The postinstall behavior is a package-local binary shim for the Factory Droid CLI, with registry downloads limited to the matching platform package and the npm token bound to npmjs.org hosts. No credential harvesting, agent-control writes, or self-install chain appears in the inspected sources.

Decision evidence
public snapshotAI called this Clean at 86.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- postinstall runs node install.js to select the matching platform binary and replace the local droid shim with a link to it.
- If the optional platform package is missing, install fetches that same-version package tarball from registry.npmjs.org and extracts package/bin/droid into this package bin directory.
- NPM_TOKEN is added only when the request host includes npmjs.org.
- The global-install PATH check only prints a suggested shell command and does not write profile or agent config files.
- Optional dependencies are same-version @factory platform packages, not another release of @factory/cli.

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