Shared React component library for Clet projects

AI Security Review

scanned 14d ago · by lpm-firewall-ai

The active postinstall chain automatically writes agent instructions and MCP configuration into consumer projects and the user's Codex config. This meets the policy for blocking unconsented install-time mutation of AI-agent control surfaces.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

Installing the package through npm with its postinstall lifecycle enabled; setup can be skipped with RFDUI_SKIP_SETUP.

Impact

Installation changes AI-agent configuration and instruction files without a separate setup command, influencing agent behavior and enabling the package's MCP server.

Mechanism

The lifecycle script runs the package CLI's setup command, which copies shared agent instructions and updates detected tools' MCP configuration, skills, or rules.

Policy narrative

During npm installation, postinstall runs setup in the consumer project. Setup writes shared agent instructions and configures detected Claude, Cursor, Codex, and OpenCode surfaces, including a machine-level Codex config. This is unconsented install-time mutation of AI-agent control surfaces.

Decision evidence

public snapshot

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

Evidence for policy risk

The package runs a postinstall script that invokes its setup command in the consumer project.
Setup automatically writes agent instructions and configures detected AI tools, including project and machine-level control surfaces.
Tool-specific installers write MCP configuration and agent instruction files without a separate user command.
