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 conditional PATH update in postinstall and package-aligned CLI, provider validation, proxy, and setup behavior. No concrete attack behavior was established.

Static reason

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

Trigger

npm installation triggers the postinstall PATH setup; the worker runs when invoked through its CLI entrypoint.

Impact

The inspected behavior enables CLI access and intended model connections; no concrete malicious effect was established.

Mechanism

The postinstall adds a marked PATH entry for the global npm bin directory. Proxy routing is gated by configured model endpoint checks, and provider setup rejects metadata and link-local destinations.

AI rationale

Source inspection found a conditional PATH update in postinstall and package-aligned CLI, provider validation, proxy, and setup behavior. No concrete attack behavior was established.

Decision evidence

public snapshot

AI called this Clean at 87.0% confidence as Benign with low false-positive risk.

Evidence for AI clean decision

The postinstall runs a PATH setup script, which conditionally adds the global npm bin directory to the user's shell profile.
Provider URL validation rejects metadata and link-local addresses.
Proxy routing applies only when the request passes configured proxy checks.
The client expert setup probes the machine and checks whether setup is available.
The CLI entrypoint starts the worker polling loop.

An OpenAI-compatible provider is the opposite — the path is part of the L13: * address. https://openrouter.ai/api/v1 is OpenRouter's documented base, and dropping the /api L14: * from it 404s every call.
