AI Security Review

scanned 3h ago · by lpm-firewall-ai

LPM flags this version as an AI-agent control-surface risk. Global installation automatically modifies Claude and Codex agent configuration and installs command hooks. Subsequent normal CLI use restores those agent-control surfaces.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

npm global installation, followed by any ordinary vibe command if the surfaces are absent or stale.

Impact

Package-controlled instructions and commands become active in broad AI-agent home directories without an explicit setup command.

Mechanism

Postinstall agent configuration mutation and persistent hook installation.

Policy narrative

The postinstall hook activates during a global npm installation and calls global setup. That setup writes package cards and skills into Claude and Codex directories and adds hooks that invoke package code on agent tool events. The CLI also repairs these surfaces whenever it is run. This is an automatic, persistent mutation of broad AI-agent control surfaces rather than an explicit user setup action.

Rationale

The package has a concrete postinstall path that installs and persists package-controlled AI-agent instructions and command hooks in user home directories. This meets the policy for malicious install-hook abuse even though no secret exfiltration was found.
