## 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:** 0.21.31
- **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.

Source inspection found no concrete attack behavior, but global postinstall can acquire a native executable automatically, so residual lifecycle risk remains. Agent configuration locations inspected were test fixtures or read-only discovery, not install-time mutation.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Suspicious
- **Recorded analysis confidence:** 73.0%
- **Started:** 2026-10-22T19:42:16.691Z

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 was identified. A global npm install can download and cache the package’s native runtime during postinstall, which leaves a lifecycle-time executable acquisition risk.

- **Trigger:** Installing the package globally through npm on a supported platform, unless native auto-fetch is disabled or the runtime is already cached.

- **Impact:** A package-selected native executable is acquired during global installation; the inspected source does not establish malicious payload behavior.

- **Evidence paths:** dist/scripts/postinstall.js, dist/cli/native-assets.js

- **Review source:** ai\_review

- **Reviewed:** 2026-10-22T19:43:29.766Z

### AI review details

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

- **Mechanism:** The postinstall path requests a release manifest, downloads a selected native archive, checks its size and SHA-256, then extracts and caches its binary.

- **Rationale:** Source inspection found no concrete attack behavior, but global postinstall can acquire a native executable automatically, so residual lifecycle risk remains. Agent configuration locations inspected were test fixtures or read-only discovery, not install-time mutation.

- **Files touched:** dist/scripts/postinstall.js, dist/cli/native-assets.js

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 73.0%

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

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for warning:** The postinstall hook runs only for global installs; local installs return without work., A global install automatically hydrates a native runtime from release assets, creating a lifecycle-time executable acquisition path., The downloaded archive is checked against the release manifest’s size and SHA-256 before extraction and caching., Native agent files are generated under user or project Codex directories, while agent management is exposed through explicit CLI commands., The inspected agent configuration target locations are test fixtures or read-only configuration discovery.

- **Evidence against:** The source inspected here does not establish credential collection, unrelated data transfer, consumer policy changes, or unconsented agent configuration mutation.

## Affected versions and remediation
