## 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:** 1.0.843
- **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.

Source inspection found a postinstall PATH adjustment and explicit project integration approvals, with no confirmed attack behavior. The suspicious scanner labels were not sufficient to establish an attack.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Clean
- **Recorded analysis confidence:** 83.0%
- **Started:** 2026-10-17T05:47:34.174Z

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 confirmed attack surface was identified. The install hook performs a narrow PATH setup, and project agent integrations use explicit approvals.

- **Trigger:** Package installation triggers the PATH setup; project hooks and MCP servers require later user approval before running.

- **Impact:** The inspected behavior supports normal CLI setup and gated agent integrations; no concrete credential theft, unconsented agent control, or other attack was established.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-17T05:48:19.284Z

### AI review details

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

- **Mechanism:** The installer adds a marked global-bin PATH entry only when absent. Project hook and MCP settings are read, while approval state is stored in user settings.

- **Rationale:** Source inspection found a postinstall PATH adjustment and explicit project integration approvals, with no confirmed attack behavior. The suspicious scanner labels were not sufficient to establish an attack.

### Review decision

- **Verdict:** Clean

- **Confidence:** 83.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** package.json runs install-path.mjs at postinstall; that code skips changes when the global bin is already on PATH and otherwise adds a marked PATH entry to a shell startup file., hooks-config.mjs requires folder-specific approval for project hooks and keeps that approval in user settings; its cited settings path is a path helper., mcp-config.mjs requires per-folder, per-server approval before project MCP servers run; its cited path is a project configuration path helper., gu-repl.mjs is the terminal agent entrypoint; gu-cli.mjs documents explicit worker-key and API-base configuration. The inspected source showed ordinary provider and worker requests, with no confirmed credential redirect to a package-selected unrelated recipient., mongo-native.mjs, coding-provider-setup.mjs, proxy-dispatcher.mjs, and agent-stop.mjs describe local database setup, user-configured model providers, per-request proxy routing, and stopping runaway agents; no concrete attack behavior was established.

- **Evidence against:** The postinstall does make a persistent shell PATH edit when needed, but the inspected code limits it to the global executable directory and marks it for idempotent setup., Scanner labels for credential redirection and dynamic execution were not borne out by the inspected source excerpts; those labels alone do not establish an attack.

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

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";

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)

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.
