AI Security Review

scanned 29d ago · by lpm-firewall-ai

LPM flags this version as an AI-agent control-surface risk. Installation automatically modifies broad, global AI-agent control surfaces. It deploys skills and agent prompts across multiple vendors and changes Claude configuration.

Static reason

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

Trigger

npm installation runs the postinstall lifecycle hook.

Impact

It can alter the behavior and available instructions of several AI coding tools without an explicit setup command.

Mechanism

Automatic cross-platform AI-agent skill, agent, and settings installation.

Policy narrative

When npm installs the package, its postinstall hook executes an installer. That installer intentionally distributes package-provided skills to all configured AI-agent platforms rather than a selected platform, installs agent prompt files, creates Peaks configuration, and can set Claude's output style. These are global agent control-surface changes made automatically rather than through an explicit user setup command.

AI rationale

This is concrete, unconsented postinstall mutation of broad foreign AI-agent control surfaces. The absence of observed exfiltration does not neutralize the automatic cross-platform control-surface writes.

Evidence

package.jsonscripts/install-skills.mjs~/.claude/skills~/.claude/agents~/.claude/output-styles~/.claude/settings.json~/.codex/skills~/.codex/agents~/.cursor/skills~/.trae/skills~/.qoder/skills~/.tongyi-lingma/skills~/.peaks/config.json.peaks/config.json

Decision evidence

public snapshot

AI identified this as a dangerous AI-agent capability at 99.0% confidence with low false-positive risk.

Evidence for policy risk

The manifest automatically runs install-skills.mjs after installation.
The installer deliberately fans out bundled skills to every listed AI platform, including global Claude, Codex, Cursor, Trae, Qoder, Lingma, Hermes, and ZCode directories.
The install hook auto-installs agent prompts and changes Claude's outputStyle setting without an explicit command.
The installer creates global Peaks configuration and can invoke an automatic project upgrade during installation.

Evidence against

No direct outbound network request or credential-exfiltration code was found in the inspected lifecycle script.
The script includes path checks and avoids overwriting some existing user-owned files.
