Portable hybrid code auditing + remediation orchestrators for arbitrary repositories.

AI Security Review

scanned 6d ago · by lpm-firewall-ai

LPM flags this version as an AI-agent control-surface risk. npm postinstall silently modifies multiple foreign, user-global AI-agent control surfaces. It installs skills, commands, plugins, and merged OpenCode 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 install of audit-tools, including dependency installation

Impact

Adds package-controlled prompts and agent commands to Codex, Claude, OpenCode, and Antigravity environments.

Mechanism

postinstall deployment of global AI-agent assets and configuration

Policy narrative

On installation, the package launches two deployers that create and overwrite global Codex and Claude skill assets, merge OpenCode configuration, and install Antigravity and Claude Desktop plugins. These mutations occur through npm postinstall rather than an explicit user setup command.

Rationale

This is a concrete unconsented postinstall mutation of foreign AI-agent control surfaces. The package’s permission hardening does not remove the lifecycle-based global control-surface write.
