AI Security Review

scanned 19d ago · by lpm-firewall-ai

LPM flags this version as an AI-agent control-surface risk. Installing the package automatically deploys package-provided commands and skills into global AI-agent directories and merges a global OpenCode configuration. It also targets the consuming repository for .gitignore management.

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 installation triggers the manifest postinstall hook.

Impact

The package changes broad, foreign AI-agent control surfaces without an explicit user command, allowing its prompts and skills to become available globally.

Mechanism

The lifecycle launcher runs two deployers that create or overwrite files under the user's Claude, Codex, and OpenCode configuration locations.

Policy narrative

A normal npm install invokes the package postinstall hook. That hook launches both deployers, which write package-controlled Claude and Codex commands and skills into global user configuration directories and merge OpenCode configuration. The same lifecycle path also manages the consumer repository's .gitignore. These changes occur without an explicit setup command, creating a broad AI-agent control surface.

AI rationale

The package performs unconsented postinstall mutation of foreign, broad AI-agent control surfaces, meeting the blocking lifecycle policy.
