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 guarded global-install PATH setup hook and product-aligned provider and proxy behavior. The inspected code did not establish a malicious attack chain.

Static reason

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

Trigger

The postinstall hook runs during package installation; other reviewed behavior requires invoking the CLI or configuring a provider or proxy.

Impact

The install hook can change shell startup configuration to make the CLI available on PATH. No credential theft, unrelated data transfer, or agent control-surface mutation was established.

Mechanism

The hook may add the package’s global bin directory to a shell startup file. Provider setup classifies metadata targets, and proxy requests are conditional on configured model endpoints and an enabled proxy.

AI rationale

Source inspection found a guarded global-install PATH setup hook and product-aligned provider and proxy behavior. The inspected code did not establish a malicious attack chain.

Decision evidence

public snapshot

AI called this Clean at 95.0% confidence as Benign with low false-positive risk.

Evidence for AI clean decision

package.json maps the postinstall hook to a PATH setup script.
The install script skips Windows, CI, local installs, temporary prefixes, and installs where the global bin directory is already on PATH.
The provider setup classifies metadata addresses and link-local ranges as unsafe targets.
Proxy routing is limited to configured model endpoints when the proxy is enabled.
The local API binds to loopback by default.

Evidence against

The postinstall script can append a marked PATH block to a shell startup file after a global install when the package bin directory is missing from PATH.
