## Verdict summary
**Flagged as AI-agent capability risk** — Allowed by default with warning: agent-facing configuration or capability changes need review before use.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Warn-only AI-agent capability risk
- **Public report status:** Published
- **Threat category:** AI-agent capability abuse
- **Selected version:** 0.3.11
- **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: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy.

The package has a CLI entry point without an install lifecycle hook. Agent configuration changes occur through explicit Grum setup or init behavior, so this is a warning-level agent capability rather than an install-time attack.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Suspicious
- **Recorded analysis confidence:** 83.0%
- **Started:** 2026-10-07T03:25:05.948Z

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:** Explicit Grum initialization can configure Cursor or Codex in the current repository. No confirmed malicious attack surface was established; the behavior is user-invoked setup.

- **Trigger:** A user runs the Grum setup or init command.

- **Impact:** The repository's supported agent integration is enabled; source inspection did not establish covert execution or data theft.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-07T03:25:46.889Z

### AI review details

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

- **Mechanism:** Initialization writes agent hook and MCP configuration and a repository rule pointer, subject to setup and project-link checks.

- **Rationale:** The package has a CLI entry point without an install lifecycle hook. Agent configuration changes occur through explicit Grum setup or init behavior, so this is a warning-level agent capability rather than an install-time attack.

- **Files touched:** grum.mjs

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 83.0%

- **Recommended action:** downgrade\_to\_warn

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for warning:** The manifest exposes a user-run CLI and has no install lifecycle hook., The flagged agent integration is a Cursor rule path used by Grum., The init command accepts Cursor or Codex and requires a linked project unless explicitly run local-only., Cursor initialization writes hook and MCP configuration files in the repository.

- **Evidence against:** Setup requires an explicit command or interactive confirmation; no unconsented npm-time agent configuration mutation is shown., The inspected integration is first-party Grum setup, and no malicious payload execution or credential exfiltration was established.
