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 9d ago · by lpm-firewall-ai

The source supports the install hook’s PATH setup and the coding-key transfer’s role in the package’s configured service workflow. Scanner hints did not establish credential theft, an unrelated fixed recipient, or malicious agent configuration changes.

Static reason

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

Trigger

Package installation triggers the postinstall PATH setup; runtime API-key storage follows an interactive prompt.

Impact

No malicious impact was established from these behaviors.

Mechanism

The hook checks PATH and shell configuration. Provider keys are submitted to the configured worker API for the coding-key feature.

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

The postinstall runs install-path.mjs, which conditionally adds the global bin directory to shell PATH when it is missing.
Worker requests use the configured API base; first-run login defaults to the package’s Go service.
The REPL prompts for a provider API key and sends it to the configured worker API for the coding-key feature.
Project hooks run only when their current fingerprint matches a saved approval; MCP server entries are handled through an explicit add-server function.
Mongo migration is presented as a command, while the provider setup vets endpoint URLs and proxy routing applies only to configured model endpoints.
Agent-stop handles ended job states and stops child processes; no malicious behavior was identified in the inspected source.
