AI Security Review

scanned 11d ago · by lpm-firewall-ai

Source inspection found guarded first-party machine onboarding, while ordinary dependency installs do not wire agent settings. The scanner’s execution and agent-integration hints are consistent with this product setup and test support; they do not establish malicious behavior.

Static reason

High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source

Trigger

A global npm install or an install invoked with --machine-setup triggers machine wiring.

Impact

No confirmed malicious impact or unconsented attack surface was established.

Mechanism

The package installs its resolver and agent integrations as onboarding; ordinary dependency installs exit before setup.

AI rationale

Decision evidence

public snapshot

AI called this Clean at 90.0% confidence as Benign with low false-positive risk.

Evidence for AI clean decision

package.json defines a postinstall hook that runs postinstall.cjs.
The postinstall guard permits machine wiring only for a global install or an explicit --machine-setup argument; other installs exit without wiring.
Machine setup connects the resolver, OpenCode plugin, and Codex hooks as first-party onboarding.
The resolver target is a fixed twing path under the user home directory.
The Codex integration targets the user’s Codex configuration path.
The inspected OpenCode adapter builds a descriptor from the session ID and selected environment and directory values.
test-support.js uses child processes to initialize throwaway Git test repositories.
