AI Security Review

scanned 9d ago · by lpm-firewall-ai

The automatic postinstall mutation of the user's Claude skills directory is a guarded first-party agent extension setup that warrants a warning. The inspected sources did not establish a concrete malicious chain that supports blocking publication.

Static reason

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

Trigger

Installing the package through npm, unless EMDEE_SKIP_POSTINSTALL=1 is set.

Impact

The installed skills become available to Claude Code and may guide later agent behavior. No credential transfer or malicious payload behavior was established in the inspected source.

Mechanism

The postinstall script launches the bundled skills installer, which copies Markdown files from the package into ~/.claude/skills.

AI rationale

Evidence

package.jsonscripts/postinstall.mjsdist/cli/skills-install.jsskills/emdee-onboarder.md~/.claude/skills/

Decision evidence

public snapshot

AI called this Suspicious at 91.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

package.json runs scripts/postinstall.mjs during installation.
The postinstall hook launches the skills installer automatically; an environment variable can skip it.
The installer defaults to the user's ~/.claude/skills directory and reads skills from this package.
The installer copies package Markdown skill files into that directory.
The copied onboarding skill describes helping users set up an EMDEE vault.
The flagged dist/mcp/server.js location contains bundled file and dependency metadata, not agent configuration logic.

Evidence against

The inspected source supports a first-party skills setup capability; it did not establish credential theft, payload execution, or another concrete attack.
