## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 14 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:** 4.5.136
- **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 manifest has no install lifecycle scripts, and the flagged agent-path code classifies repository paths rather than changing agent configuration. The CLI telemetry is limited to basic usage fields, can be disabled, and no concrete attack behavior was found.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Clean
- **Recorded analysis confidence:** 92.0%
- **Started:** 2026-10-18T14:45:34.430Z

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 attack was identified in the inspected source. The automatic outbound behavior found is low-detail CLI usage telemetry to the Hub endpoint.

- **Trigger:** Running a CLI command triggers its pre-action hook; setting MMI\_TELEMETRY=off disables the telemetry request.

- **Impact:** The inspected telemetry payload contains no credentials or file contents, and no agent configuration takeover or other attack was identified.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-18T14:47:25.035Z

### AI review details

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

- **Mechanism:** The request posts the command name, client version, CI status, and operating system to the Hub telemetry route.

- **Rationale:** The manifest has no install lifecycle scripts, and the flagged agent-path code classifies repository paths rather than changing agent configuration. The CLI telemetry is limited to basic usage fields, can be disabled, and no concrete attack behavior was found.

- **Network endpoints:** https://tqxxwzftic.execute-api.eu-central-1.amazonaws.com/telemetry/cli-call

### Review decision

- **Verdict:** Clean

- **Confidence:** 92.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** package.json declares no install lifecycle scripts, so package installation does not trigger the bundled CLI., The flagged agent paths are used to classify repository paths; this code does not write agent configuration., CLI telemetry sends the command name, client version, CI status, and operating system; MMI\_TELEMETRY=off disables it., The pre-action hook sends telemetry when a CLI command runs., Plugin repair is exposed as an explicit plugin-heal command.

- **Evidence against:** Usage telemetry is enabled by default, but its inspected payload contains no credentials or file contents.
