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 5d ago · by lpm-firewall-ai

The postinstall behavior is a guarded PATH repair, and the reviewed agent configuration code requires explicit approval or user-invoked changes. The credential transfer is tied to a user-entered coding key and the worker API feature; the inspected source does not establish an unrelated or covert recipient.

Static reason

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

Trigger

The PATH repair runs during package postinstall; other reviewed actions require CLI use or user input.

Impact

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

Mechanism

The installer conditionally adds the global bin directory to shell profiles. Credential handling routes a user-entered coding key to the configured worker API.

AI rationale

Decision evidence

public snapshot

AI called this Clean at 86.0% confidence as Benign with low false-positive risk.

Evidence for AI clean decision

The postinstall runs install-path.mjs, which guards local installs and adds the global bin directory to PATH when needed.
Project hooks are kept pending until approved; the approval is stored in Gu settings, not written to Claude settings.
MCP server configuration changes occur through explicit add commands; project servers are approved for the current folder.
The user enters the coding provider key in the terminal, and the app sends it through a worker-key-authenticated request to its configured API.
Other flagged paths implement ordinary product functions: provider model listing, model-endpoint proxying, child shutdown, MongoDB setup, and user-guided browser extension setup.
