## Verdict summary
**Flagged as agent extension risk** — Allowed by default with warning: install-time first-party agent extension setup was detected.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Warn-only agent extension risk
- **Public report status:** Published
- **Threat category:** Agent extension lifecycle risk
- **Selected version:** 0.9.2
- **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 source confirms automatic postinstall setup of package-owned agent guidance, which merits a warning under the agent integration policy. The inspected behavior does not support a malicious verdict or publish block.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Suspicious
- **Recorded analysis confidence:** 89.0%
- **Started:** 2026-10-11T18:10:41.688Z

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:** The postinstall hook automatically installs package-owned coding-agent guidance in the user's agent directory. This is a guarded warning-level agent setup behavior; no concrete malicious action was identified.

- **Trigger:** Installing the package with npm triggers its postinstall script.

- **Impact:** The installed guidance can influence later coding-agent sessions; the inspected code does not establish a foreign or broad agent control-surface takeover.

- **Evidence paths:** package.json, scripts/install-agents.mjs, global/AGENTS.md

- **Review source:** ai\_review

- **Reviewed:** 2026-10-11T18:11:22.371Z

### AI review details

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

- **Mechanism:** The script copies the bundled AGENTS.md into ~/.pi/agent/AGENTS.md when the file is missing or differs, and initializes a default theme setting when needed.

- **Rationale:** The source confirms automatic postinstall setup of package-owned agent guidance, which merits a warning under the agent integration policy. The inspected behavior does not support a malicious verdict or publish block.

- **Files touched:** scripts/install-agents.mjs, global/AGENTS.md

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 89.0%

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

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for warning:** The package runs scripts/install-agents.mjs during postinstall., That installer copies bundled guidance to the current user's .pi/agent/AGENTS.md when it is absent or differs., The bundled file describes itself as behavioral guidance for coding agents, making this a first-party agent setup with an automatic install trigger.

- **Evidence against:** The installer writes only the package's bundled guidance to that agent file and initializes a missing theme setting; inspected code showed no foreign agent configuration target., The flagged browser test is explicitly an end-to-end test, and the browser automation files inspect or control Chrome through its DevTools interface.
