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 package-aligned worker API flow and a postinstall PATH helper, but no concrete credential theft, malicious payload execution, or unconsented agent-control modification. The scanner’s execution and network signals correspond to inspected CLI features and do not establish an attack.

Static reason

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

Trigger

Installing the package runs its postinstall helper; other reviewed behavior is reached through CLI or REPL use.

Impact

The inspected behavior supports the package’s CLI and worker features; no concrete malicious effect was established.

Mechanism

The worker API receives coding keys at the configured API base, which defaults to the package’s own service. The inspected configuration code reads agent settings and exposes configuration operations without showing an install-time agent-control write.

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 maps the CLI entry points and runs install-path.mjs during postinstall.
The REPL sends coding keys to its configured worker API; the default API is the package’s own service, and the request uses the worker key for authentication.
The inspected hooks and MCP configuration code reads project and user configuration paths; it does not show an install-time write to an agent control surface.
Inspected execution-related modules support package functions: MongoDB setup, worker CLI operation, provider setup, per-request proxying, graceful agent stopping, and local API startup.
install-path.mjs gates its PATH setup on npm global-install context.

Evidence against

Static hints flagged credential forwarding, lifecycle behavior, and process execution, but the inspected source did not establish credential theft or unconsented agent-control modification.
