AI Security Review

scanned 25d ago · by lpm-firewall-ai

LPM flags this version as an AI-agent control-surface risk. Installing this package automatically installs a separate global AI-agent CLI if none is found. The behavior runs before the user invokes this package's command.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source

Trigger

npm installation runs the postinstall hook on a system without a detected supported AI CLI.

Impact

The package changes the user's global AI-agent control surface and introduces a remotely supplied executable without explicit consent.

Mechanism

Install-time global installation of a foreign AI-agent executable.

Policy narrative

During npm installation, package.json triggers scripts/postinstall.js. That script calls ensureDefaultKernel, which detects installed AI CLIs and, if none are available, executes npm install -g opencode-ai. This occurs without a user command and installs a separate global AI-agent executable. The opt-out environment variable does not establish consent because the default lifecycle action has already been selected by the package.

AI rationale

The postinstall hook automatically mutates a foreign global AI-agent environment by installing opencode-ai. This is an unconsented install-time AI control-surface change, so it meets the publish-block policy.
