## 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:** 1.63.1
- **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 automatic repair of an existing Codex wrapper is a guarded integration lifecycle risk that warrants a warning. The inspected sources do not establish broad control-surface mutation or another concrete attack.

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 install hook can attempt a repair of an existing Codex wrapper; the inspected code limits this to the wrapper path and also prints opt-in setup guidance. The CLI separately adds integrations and daily scheduling when invoked.

- **Trigger:** Installing the package triggers postinstall; running hippo init or hippo setup activates CLI integrations.

- **Impact:** An existing Codex wrapper may be changed during installation. The inspected source does not establish unconsented broad agent configuration changes or credential exposure.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-07T20:28:45.824Z

### AI review details

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

- **Mechanism:** Postinstall calls the Codex wrapper repair function. The CLI detects existing agent configuration and offers or applies hooks, while setup supports dry-run and scheduling controls.

- **Rationale:** The automatic repair of an existing Codex wrapper is a guarded integration lifecycle risk that warrants a warning. The inspected sources do not establish broad control-surface mutation or another concrete attack.

- **Files touched:** package.json, dist/postinstall.js, dist/cli/init.js, dist/cli/setup.js, dist/scheduler.js, dist/cli/shared.js

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 81.0%

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

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for warning:** package.json runs a package-local postinstall script., Postinstall attempts to repair an already installed Codex wrapper and prints setup guidance., The init detector recognizes existing agent configuration files; init is an explicit CLI flow., hippo setup detects integrations and supports dry-run; scheduling can be skipped., Workspace registration stores normalized project paths in the package registry., The daily schedule is configured through CLI setup code.

- **Evidence against:** The package has an install-time hook that can modify an existing Codex launcher wrapper, leaving a guarded integration risk.
