AI Security Review

scanned 28d ago · by lpm-firewall-ai

LPM flags this version as an AI-agent control-surface risk. Installing the package automatically overwrites a named skill in three AI-agent control surfaces under the user's home directory. The copied skill provides agent-facing instructions and can change those agents' available behavior.

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 postinstall during package installation

Impact

Unconsented mutation of Claude, generic-agent, and Codex skill directories.

Mechanism

Automatic cross-platform AI-agent skill installation and replacement

Policy narrative

On npm installation, postinstall runs scripts/install-skill.mjs. Unless an opt-out environment variable is already set, it removes and copies the package's scriptctl skill into three user-home AI-agent skill roots. This modifies control surfaces belonging to Claude, generic agents, and Codex without an interactive user action or consent prompt.

AI rationale

The automatic lifecycle hook broadly mutates foreign AI-agent control surfaces and replaces existing extension content. This meets the install-control-surface blocking rule despite the available opt-out.
