## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 11 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:** 0.18.14
- **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 setup command, and the flagged git code is a bounded sparse documentation clone. Source inspection found no concrete malicious behavior.

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 a Playwright browser, while runtime fetchers retrieve documentation supplied through their APIs.

- **Trigger:** Package installation downloads Chromium; callers must invoke documentation sync or fetch APIs for network activity.

- **Impact:** No unconsented data collection, control-surface mutation, or destructive action was found.

- **Review source:** ai\_review

- **Reviewed:** 2026-09-15T06:52:22.767Z

### AI review details

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

- **Mechanism:** Package-aligned browser setup and documentation retrieval.

- **Rationale:** The postinstall hook is a transparent Playwright browser setup command, and the flagged git code is a bounded sparse documentation clone. Source inspection found no concrete malicious behavior.

### Review decision

- **Verdict:** Clean

- **Confidence:** 94.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** Install hook runs Playwright's Chromium installer., Git helper invokes git only to sparse-clone configured GitHub documentation paths.

- **Evidence against:** No self-dependency or hidden lifecycle chain is present., Network access is in exported, user-invoked documentation fetch functions., No credential harvesting, exfiltration, shell evaluation, agent-control writes, or stealth persistence was found.

Public source snippet (untrusted):

```javascript
matchType = previous_version_dangerous_delta
matchedPackage = @devflow-tools/knowledge-engine@0.18.20
matchedIdentity = npm:[redacted]:0.18.20
similarity = 0.767
summary = stored previous version shares package body but lacks this dangerous source file
