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

The postinstall behavior is a conditional PATH setup for this CLI, and the reviewed network and process operations occur in package functions rather than showing hidden collection or execution. The inspected evidence does not establish a concrete attack surface.

Static reason

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

Trigger

Package installation may run the postinstall hook; other reviewed behavior requires invoking its CLI or setup function.

Impact

No confirmed malicious effect or attack surface was established in the inspected source.

Mechanism

The postinstall hook checks whether the package bin directory is already on PATH and returns if so; otherwise it adds that directory to selected shell startup files. Reviewed requests use configured service endpoints, and proxy routing is conditional.

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 hook runs install-path.mjs, which only self-executes when directly invoked.
The installer skips changes when the global bin directory is already on PATH and adds that directory to shell startup files otherwise.
gu-cli uses the worker key for an explicit token-usage command to its configured local API base.
Client Expert installs API dependencies in its API directory when that setup path is invoked.
The provider setup classifies loopback, private, and link-local addresses as distinct local network ranges.
The proxy routes requests through a proxy only when shouldProxy allows it; other requests use ordinary fetch.

Evidence against

The package has a postinstall hook that can modify the user's shell startup files.
The CLI can spawn an npm dependency installation during Client Expert setup.
