AI Security Review

scanned 2h ago · by lpm-firewall-ai

LPM flags this version as an AI-agent control-surface risk. A global npm install silently modifies Claude, Codex, and Hermes agent homes. It injects instruction cards and skills and registers command hooks.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review

Trigger

Installing the package globally through npm without VIBE_SKIP_SETUP.

Impact

The package gains persistent influence over AI-agent instructions and tool-event execution across existing client homes.

Mechanism

Postinstall calls global setup to write agent control files and command hooks.

Policy narrative

On global npm installation, the postinstall script invokes setup without an explicit agent-configuration command. Setup detects AI client homes and writes persistent instruction cards and skills, then adds command hooks for Bash and edit events. This mutates broad, pre-existing AI-agent control surfaces and causes package code to run during later agent activity.

Rationale

This is an automatic install-time mutation of foreign AI-agent control surfaces, including persistent instructions and command hooks. The global-only guard does not provide consent for those changes.
