AI Security Review

scanned 9d ago · by lpm-firewall-ai

Source inspection confirms automatic, opt-out-only installation of package-owned Claude Code skills. This meets the warning category for first-party agent extension setup, but the reviewed behavior does not establish a concrete malicious attack.

Static reason

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

Trigger

Installing the package runs its postinstall hook, unless the opt-out environment variable is set.

Impact

The installed skills become available to Claude Code; the reviewed source does not establish a separate malicious action.

Mechanism

The hook launches an installer that copies Markdown skills into the user’s global Claude Code skills directory.

AI rationale

Evidence

package.jsonscripts/postinstall.mjsdist/cli/skills-install.js~/.claude/skills

Decision evidence

public snapshot

AI called this Suspicious at 94.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The manifest defines a postinstall script that runs the package’s installer.
The postinstall script runs that installer unless an environment opt-out is set.
The installer targets the user’s global Claude Code skills directory and copies package Markdown skills there.
The requested location in the MCP bundle is embedded package metadata, not an agent settings mutation.

Evidence against

The reviewed source establishes first-party skill setup, but does not establish credential theft, a reverse shell, or another concrete attack.
The installer copies Markdown skill files; the reviewed code does not show it changing agent settings or enabling private-content export.
