## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 10 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:** 0.18.19
- **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 a transparent Playwright browser download, and the inspected network and subprocess logic is scoped to documentation ingestion. No concrete malicious behavior or self-dependent lifecycle chain was found.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Clean
- **Recorded analysis confidence:** 93.0%

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 malicious attack surface was established. Installation only requests Playwright's Chromium provisioning; documentation retrieval occurs through exported runtime functions.

- **Trigger:** Package installation for browser provisioning, or an application calling documentation-ingestion APIs.

- **Impact:** Downloads a browser at install time and retrieves requested documentation at runtime.

- **Review source:** ai\_review

- **Reviewed:** 2026-09-09T11:45:35.408Z

### AI review details

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

- **Mechanism:** Playwright browser provisioning and explicit documentation retrieval.

- **Rationale:** The postinstall hook is a transparent Playwright browser download, and the inspected network and subprocess logic is scoped to documentation ingestion. No concrete malicious behavior or self-dependent lifecycle chain was found.

### Review decision

- **Verdict:** Clean

- **Confidence:** 93.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** The package has a postinstall hook that invokes Playwright to provision Chromium., Runtime code can fetch documentation from Context7 when its exported fetch function is called.

- **Evidence against:** The lifecycle hook contains no package code, shell chaining, environment access, or project-file mutation., No self-dependency, credential harvesting, exfiltration, dynamic code execution, or persistence logic was found., Network and git operations are explicit documentation-ingestion functions, not import-time execution.

- **Confidence:** 65.0%

Package source contains URL literals.

### 8. Medium: Structural Risk Force Deep Review
- **Category:** Artifact Inventory
- **Confidence:** 70.0%

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

### 9. Low: Suspicious Lifecycle Evidence
- **Category:** Manifest
- **Confidence:** 93.0%
- **Path:** package.json
- **Public source:** [View source](<https://unpkg.com/@devflow-tools/knowledge-engine@0.18.19/package.json>)

The package has a postinstall hook that invokes Playwright to provision Chromium.

Public source snippet (untrusted):

```json
"scripts": {
    "build": "tsc -b",
    "test": "node ../../node_modules/.bin/vitest run",
    "typecheck": "tsc --noEmit",
    "clean": "rm -rf dist",
    "postinstall": "playwright install chromium || true"
  },
```

### 10. Low: Ai Review Evidence
- **Category:** Ai Review
- **Confidence:** 93.0%
- **Path:** dist/context7-fetcher.js
- **Public source:** [View source](<https://unpkg.com/@devflow-tools/knowledge-engine@0.18.19/dist/context7-fetcher.js>)

Public source snippet (untrusted):

```javascript
export async function fetchFromContext7(context7Id, pluginName) {
    const topics = TOPIC_QUERIES[pluginName];
    if (!topics || topics.length === 0)
        return [];
    const results = [];
    const seen = new Set();
    for (const topic of topics) {
        try {
            const url = `${CONTEXT7_API}?libraryId=${encodeURIComponent(context7Id)}&query=${encodeURIComponent(topic)}&type=txt`;
            const response = await fetch(url);
            if (!response.ok)
                continue;
            const text = await response.text();
            if (!text || text.length < 100)
```
