## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 16 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:** 1.53.0
- **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 static alerts map to package-aligned agent integration and scheduled maintenance. Source inspection indicates setup is an explicit CLI action and install-time Codex integration is repair-only for a prior opt-in, so no malicious behavior is established.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Clean
- **Recorded analysis confidence:** 79.0%
- **Started:** 2026-10-07T20:26:47.867Z

- **Download time:** 511 ms
- **Static scan time:** 3867 ms
- **AI review time:** 27328 ms
- **Total time:** 31709 ms

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:** Agent hook and plugin configuration can be installed by the CLI, and an opted-in Codex wrapper can be repaired during package installation. No confirmed malicious attack surface was established from the inspected behavior.

- **Trigger:** Explicit invocation of \`hippo setup\` or installation when a user already opted into the Codex wrapper.

- **Impact:** Agent behavior can be extended through installed hooks or plugins, with configuration initiated by the user; the inspected install path does not establish unconsented setup.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-07T20:27:19.576Z

### AI review details

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

- **Mechanism:** The CLI configures detected agent integrations; postinstall only repairs the existing Codex wrapper and prints setup nudges.

- **Rationale:** The static alerts map to package-aligned agent integration and scheduled maintenance. Source inspection indicates setup is an explicit CLI action and install-time Codex integration is repair-only for a prior opt-in, so no malicious behavior is established.

- **Files touched:** package.json, scripts/postinstall.cjs, dist/postinstall.js, dist/cli.js, dist/hooks.js

### Review decision

- **Verdict:** Clean

- **Confidence:** 79.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** The package postinstall runs a local helper; the helper describes Codex wrapper repair as limited to users who previously opted in., The CLI includes configuration targets for several coding agents, and setup calls the hook installation functions., Scheduler behavior stores registered workspaces and runs Hippo maintenance commands against workspaces containing a \`.hippo\` directory., Embedding provider code reads the configured provider settings; the inspected source did not establish credential forwarding to an unrelated endpoint.

- **Evidence against:** The postinstall helper does not perform first-time agent setup; it prints setup nudges and repairs an existing opted-in Codex wrapper., Agent configuration installation is available through the explicit \`hippo setup\` command., The reviewed capture, hook declaration, and hook implementation excerpts did not establish malicious behavior.
