@tiens.nguyen/gu-cli@1.0.796

Gu CLI — the gu terminal plus the local worker that runs agent / OCR / PDF / embedding jobs on your Mac (Ollama / MLX / OpenAI-compatible).

AI Security Review

scanned 14d ago · by lpm-firewall-ai

Source inspection found a postinstall PATH repair and user-invoked agent configuration features, but no concrete malicious behavior. The credential and execution findings are consistent with the CLI’s configured service and visible MongoDB setup behavior.

Static reason

One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source

Trigger

Package installation triggers the postinstall PATH repair; agent setup and configuration changes require explicit CLI or REPL actions.

Impact

The inspected behavior does not establish credential theft, unconsented agent control changes, or another concrete attack.

Mechanism

The postinstall script adds the global bin directory to a shell startup file when needed. Project hooks remain inactive until approved, and worker requests send the key to the configured API base.

AI rationale

Decision evidence

public snapshot

AI called this Clean at 90.0% confidence as Benign with low false-positive risk.

Evidence for AI clean decision

The postinstall hook is limited to global PATH repair and skips local installs; it does not modify an AI agent’s configuration.
Project hooks require folder-specific approval before they run, and approval is saved in gu’s own settings.
MCP configuration paths are used by explicit CLI commands; the inspected code does not show unconsented install-time agent configuration changes.
The REPL sends its worker key to the configured API base, and device login uses the package’s default service endpoint.
The flagged native process behavior supports visible MongoDB setup steps; the proxy dispatcher attaches routing per request.
The client expert code merges its API base and worker key into local worker settings.
