AI Security Review

scanned 9d ago · by lpm-firewall-ai

LPM flags this version as an AI-agent control-surface risk. npm install automatically mutates several unrelated global AI-agent control surfaces. It installs conversation skills/commands and merges agent permission configuration without an explicit setup command.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review

Trigger

npm postinstall

Impact

Subsequent Codex, Claude, OpenCode, or Gemini sessions can load package-supplied instructions and command permissions.

Mechanism

global AI-agent skill, plugin, command, and configuration installation

Policy narrative

Installing the npm package invokes postinstall, which writes and overwrites global skills and slash-command assets for Codex and Claude, merges OpenCode configuration, and installs Gemini plugins. The installed assets direct later agent sessions to run package commands and may auto-dispatch subagents. This is unconsented install-time mutation of foreign, broad AI-agent control surfaces.

Rationale

The postinstall behavior is concrete, automatic, and targets multiple foreign global agent configurations. This meets the blocking policy even though the package uses package-branded assets and its installer performs no observed network call.
