AI Security Review

scanned 5d ago · by lpm-firewall-ai

LPM flags this version as an AI-agent control-surface risk. The npm postinstall hook installs agent instructions into Muse's user-wide skill catalog without consent. Those instructions claim priority over AGENTS.md.

Static reason

One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review

Trigger

Installing the package while Muse is available on PATH and the bundled skill exists.

Impact

Changes a foreign agent's persistent instruction surface beyond the installing project.

Mechanism

The lifecycle script invokes Muse skill installation with user scope, --force, and suppressed output.

Policy narrative

An npm installation automatically invokes the postinstall script. When Muse is available, the script silently force-installs the bundled skill at user scope. The skill directs subsequent agent behavior and claims precedence over AGENTS.md for Lemma usage. This crosses from package installation into unconsented mutation of a foreign agent's global instruction catalog.

AI rationale

Inspected source establishes unconsented install-time mutation of Muse's user-wide agent control surface. This meets the blocking policy independently of scanner similarity labels.

Evidence

package.jsonbin/postinstall.js.agents/skills/lemma/SKILL.md

Decision evidence

public snapshot

AI identified this as a dangerous AI-agent capability at 98.0% confidence with false-positive risk.
