## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 12 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:** 0.3.26
- **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 scanner’s process and network signals correspond to CLI features visible in the bundled source, and the manifest declares no install hook. Agent setup is user-invoked and asks for confirmation; the inspected source showed no concrete malicious behavior.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Clean
- **Recorded analysis confidence:** 94.0%

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 concrete attack surface was identified in the inspected source. The package provides a repository design-check CLI with explicit agent setup and Grum service integration.

- **Trigger:** A user invokes the grum CLI; agent configuration changes occur through its init/setup flow.

- **Impact:** No unauthorized configuration change, unrelated credential disclosure, or other concrete attack impact was established.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-14T04:02:40.279Z

### AI review details

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

- **Mechanism:** The CLI checks repository files, can write agent hook and MCP configuration during setup, and sends authenticated API requests to app.grum.so.

- **Rationale:** The scanner’s process and network signals correspond to CLI features visible in the bundled source, and the manifest declares no install hook. Agent setup is user-invoked and asks for confirmation; the inspected source showed no concrete malicious behavior.

- **Files touched:** grum.mjs

- **Network endpoints:** app.grum.so

### Review decision

- **Verdict:** Clean

- **Confidence:** 94.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** package.json identifies a repository design-check CLI and points its executable to grum.mjs; the inspected manifest has no lifecycle hook., The flagged source location lists a Cursor rule path used by the design-check logic; it does not perform an agent configuration write., Agent setup prompts the user to confirm or decline before proceeding., The init path writes agent hook and MCP configuration files when that command is invoked., The CLI sends authenticated API requests to its fixed Grum service origin, app.grum.so., The command dispatcher exposes init as an explicit CLI command.

- **Evidence against:** No install-time execution is declared in package.json., The inspected network and process calls fit the CLI’s repository checks, browser capture, Grum authentication, and explicit setup functions; no unrelated credential transfer or concrete attack behavior was identified.

## Affected versions and remediation
