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

Inspected source supports package-aligned CLI setup and configured worker/provider communication, not the scanner’s claimed hidden credential redirection. The package has a postinstall hook, but the inspected hook is gated to global installs and updates PATH; examined agent configuration is approval-gated or read-oriented.

Static reason

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

Trigger

npm postinstall for a global install; project hook execution occurs later when using the CLI and after approval.

Impact

The inspected behavior supports normal CLI setup and user-controlled agent integrations; no concrete malicious effect was established.

Mechanism

The postinstall adds the global binary directory to an appropriate shell profile when missing. Agent hook settings are read and project hooks are included only when approved; MCP settings are read for server configuration.

AI rationale

Decision evidence

public snapshot

AI called this Clean at 91.0% confidence as Benign with low false-positive risk.

Evidence for AI clean decision

package.json exposes gu CLI entrypoints and a postinstall hook limited to install-path.mjs.
install-path.mjs checks for a global npm install before adding the global bin directory to the shell PATH.
The worker reads its API base and worker key from environment configuration; the inspected key path is intended for OpenAI-compatible or Ollama cloud coding backends.
The client-expert helper sends configured model keys to its local API endpoint, authenticated with the worker key.
The indicated hook and MCP locations identify Claude configuration paths; inspected logic reads configuration, and project hooks are approval-gated before use.
Other flagged modules contain job-stop status handling, a Homebrew installer command, provider model-list auth, and proxy routing rationale; these inspected excerpts do not establish a separate attack.

Evidence against

No inspected source demonstrates a prompted provider credential being silently redirected to an unrelated recipient.
No inspected source demonstrates unconsented install-time mutation of a foreign or broad AI-agent control surface.
