@haus-tech/haus-workflow@5.10.1

Haus AI workflow CLI for Claude Code.

AI Security Review

scanned 10d ago · by lpm-firewall-ai

LPM flags this version as an AI-agent control-surface risk. A global npm installation automatically modifies the user's Claude Code control surface. It adds agent-related configuration and command hooks without an interactive consent step.

Static reason

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

Trigger

Installing the package globally through npm outside CI, unless the opt-out environment variable is already set.

Impact

The package gains automatic execution in the user's Claude Code workflow and can influence agent tool handling and session startup.

Mechanism

The postinstall hook launches the package CLI install command, which seeds the Claude configuration and installs hooks for tool and session events.

Policy narrative

The package declares a postinstall hook. On qualifying global installs, that hook launches its CLI with an install flag. The CLI writes Haus-managed Claude Code skills, agents, and hook settings, including commands attached to tool-use and session-start events. This is an unconsented install-time mutation of a broad AI-agent control surface.

AI rationale

The automatic global lifecycle path installs persistent Claude Code hooks and agent configuration. This meets the policy threshold for blocking unconsented install-time mutation of a broad AI-agent control surface.
