## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 20 low-signal pattern(s) reviewed.

- **Verdict:** Clean
- **Product-default install policy:** Allow
- **Firewall policy:** No policy match
- **Public report status:** Published
- **Threat category:** None published
- **Selected version:** 1.0.846
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions.

AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy.

The postinstall hook is limited to a conditional global PATH convenience. The flagged credential flow stores a prompted provider key through the package's worker API and uses it with the configured coding backend; no independent attack behavior was established.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Clean
- **Recorded analysis confidence:** 96.0%
- **Started:** 2026-10-18T13:45:20.803Z

The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs.

## Security analysis

### Published attack-surface review

- **Summary:** No concrete attack was identified. The inspected lifecycle and runtime behaviors support CLI setup and configured model use.

- **Trigger:** The PATH helper runs during npm postinstall; coding-key handling occurs after the user supplies a provider key and a worker job requests it.

- **Impact:** No malicious effect was established from the inspected source.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-18T13:47:07.887Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** The installer conditionally adds the global npm bin directory to an eligible shell profile. The runtime stores a prompted key through the worker API and uses it with the configured coding endpoint.

- **Rationale:** The postinstall hook is limited to a conditional global PATH convenience. The flagged credential flow stores a prompted provider key through the package's worker API and uses it with the configured coding backend; no independent attack behavior was established.

- **Network endpoints:** https://chat-api-v2.gucli.com

### Review decision

- **Verdict:** Clean

- **Confidence:** 96.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** package.json runs install-path.mjs at postinstall; it only adds a marker-wrapped global npm bin PATH entry when the install context qualifies and that directory is missing from PATH., The terminal prompts for a coding-provider key and stores it through the worker-authenticated API. Jobs retrieve the key by job ID and use it with the configured coding backend; the provider URL is entered by the user and validated., Project hooks and MCP servers are gated on approval. The REPL reports pending project configuration and shows the approval commands., mongo-native.mjs defines MongoDB setup steps using Homebrew's mongodb-community package., proxy-dispatcher.mjs routes a request through a proxy only when the configured routing check passes., agent-stop.mjs sends a stop signal to a child process and escalates after a grace period.

```javascript
L161: if (!brew) return false;
L162: return (await run(brew, ["trust", "--help"], { env: { ...process.env, HOMEBREW_NO_AUTO_UPDATE: "1" } })) === 0;

- **Path:** gu-cli.mjs
- **Public source:** [View source](<https://unpkg.com/@tiens.nguyen/gu-cli@1.0.846/gu-cli.mjs>)

Manifest-reachable source sends a prompted API credential to a fixed unofficial gateway and persists the redirection.

Public source snippet (untrusted):

```javascript
Manifest-reachable source captures an API credential, sends it to a fixed unofficial gateway, and persists that redirection in agent or shell configuration.
gu-cli.mjs:
import { mkdir, mkdtemp, readFile, rm, stat, unlink, writeFile } from "node:fs/promises";
import { writeFileSync, unlinkSync } from "node:fs";
await writeFile(
// an API key we deliberately don't hold, so an unauthenticated probe returns 401 and
const { createInterface } = await import("node:readline/promises");

Public source snippet (untrusted):

```javascript
L19: import { mkdir, mkdtemp, readFile, rm, stat, unlink, writeFile } from "node:fs/promises";
L20: import { execFile as execFileCallback, spawn } from "node:child_process";
L21: import { createHash, randomUUID } from "node:crypto";

Source reaches cloud instance metadata or link-local credential endpoints.

Public source snippet (untrusted):

```javascript
L12: * a log means the box. 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. So this keeps the path and mirrors the API's normalizeOpenAiV1Root
...
L47: if (a === 169 && b === 254) return "link-local"; // includes 169.254.169.254 (IMDS)

sizeBytes = 4248
magicHex = [redacted]
```

### 19. Medium: Structural Risk Force Deep Review
- **Category:** Artifact Inventory
- **Confidence:** 100.0%

Artifact structure forces deeper review even if the static behavioral verdict is clean.
