AI Security Review

scanned 26d ago · by lpm-firewall-ai

LPM flags this version as an AI-agent control-surface risk. Installing the package runs a postinstall hook that installs its bundled skill into detected AI-agent directories. It scans both a fixed cross-vendor list and additional local agent skill directories.

Static reason

One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source

Trigger

npm installation runs postinstall.

Impact

The package modifies AI-agent control surfaces without an explicit user command, allowing its instructions to be loaded by those tools.

Mechanism

Automatic cross-agent skill discovery and file installation.

Policy narrative

On npm installation, postinstall invokes the CLI's skill installer. That installer detects several AI coding tool directories, scans for additional agent skill directories, creates package-specific skill folders, and copies bundled instructions there. This cross-vendor AI-agent configuration mutation occurs automatically rather than through an explicit user command.

AI rationale

The automatic postinstall path mutates a broad, foreign AI-agent control surface. Safeguards against overwriting existing skill directories do not remove the unconsented installation behavior.
