AI Security Review

scanned 28d ago · by lpm-firewall-ai

LPM flags this version as an AI-agent control-surface risk. A global npm install automatically modifies AI-agent home configuration and installs package-controlled hooks. It writes instruction cards, skills, and command-hook entries for Claude or Codex.

Static reason

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

Trigger

Global npm installation of the package.

Impact

Future agent sessions can load package instructions and execute package hook commands without an explicit setup command.

Mechanism

Postinstall-driven AI-agent configuration and hook injection.

Policy narrative

On global installation, the lifecycle hook invokes global setup. That setup detects or defaults to agent homes, writes Claude or Codex instruction and skill files, and adds command hooks for agent lifecycle events. These changes affect broad, pre-existing AI-agent control surfaces without requiring the user to run the package command or explicitly approve setup.

AI rationale

This is an unconsented postinstall mutation of broad AI-agent control surfaces, including automatically executed hook commands. The global-install guard does not establish consent for modifying those agent configurations.
