## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 25 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:** 2.16.3
- **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 lifecycle hook performs a bounded Jujutsu installation, while the reviewed runtime behavior is consistent with Rudder's workspace, agent, and telemetry features. Similarity and network scanner hints did not establish malicious behavior in the inspected source.

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

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 malicious attack surface was identified in the inspected source. The postinstall hook provisions jj, and cloud credential staging occurs within Rudder's cloud workspace flow.

- **Trigger:** Package installation invokes postinstall; cloud snapshot behavior is activated through cloud workspace commands.

- **Impact:** The inspected behavior supports package setup and remote workspace use; no concrete attack was established.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-16T01:16:46.178Z

### AI review details

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

- **Mechanism:** The hook checks for jj and may invoke brew or cargo to install it. Cloud commands stage a workspace snapshot and send it through the Rudder Cloud client.

- **Rationale:** The lifecycle hook performs a bounded Jujutsu installation, while the reviewed runtime behavior is consistent with Rudder's workspace, agent, and telemetry features. Similarity and network scanner hints did not establish malicious behavior in the inspected source.

### Review decision

- **Verdict:** Clean

- **Confidence:** 93.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** package.json invokes a postinstall script that skips when configured to do so or when jj is present, and otherwise installs the Jujutsu tool., Cloud workspace commands build and send snapshots through the Rudder Cloud client; credential staging is part of that flow to prepare the remote agent workspace., The indicated Claude and Codex integration locations read local conversation and model data., Scheduled improvement setup is an explicit command, and its defaults require review before publishing a release., Improvement collection redacts error excerpts, and feedback text is scrubbed before sending., Other reviewed behavior is scoped to Rudder's home directory, a token-guarded loopback board, and updating this package.

## Affected versions and remediation

This report applies to @viraatdas/rudder@2.16.3.

- Review the evidence and your use of @viraatdas/rudder@2.16.3 before allowing it. Restrict the permissions described in this report.
- Choose an independently verified alternative or release. This report does not establish that other versions are safe.
