Stable terminal UI for Codex and Claude Agent SDK

AI Security Review

scanned 3h ago · by lpm-firewall-ai

Installing the package automatically mutates the user-level skill directories for both Codex and Claude. It also installs Python dependencies into the user environment.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

npm installation, through the postinstall lifecycle hook.

Impact

Package-authored agent instructions become available in existing Codex and Claude installations without an explicit setup command, and the installer can delete stale files in those target skill directories.

Mechanism

Automatic cross-agent skill deployment and user-level dependency installation.

Attack narrative

During npm installation, postinstall runs install-skills.mjs. That script copies package-controlled skills into both the Codex and Claude user configuration trees and prunes files from those destinations. The installed search skill then supplies mandatory agent instructions for bypassing blocked sites. The same lifecycle hook invokes pip with --user, modifying the user's Python environment without an explicit command.

Rationale

This package has a concrete, unconsented postinstall chain that mutates broad third-party AI-agent control surfaces and a user dependency environment. The behavior meets the install-hook abuse blocking policy even without proof of secret theft.

Decision evidence

public snapshot

AI called this Malicious at 98.0% confidence as Malware with low false-positive risk.

Evidence for block

The automatic postinstall hook runs two package-controlled installers.
The installer writes bundled skills into both Codex and Claude user skill directories.
It recursively copies files and removes destination files absent from the package source.
Postinstall also runs a user-level pip install.
The installed search skill directs agents to retry blocked sites with browser and TLS-impersonation methods.

Evidence against

No network request or credential collection is performed directly by the postinstall script.
The benchmark helper only runs fixed public test URLs when explicitly invoked.
The packaged search code includes safeguards against treating fetched web text as instructions.
