## 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:** 1.63.2
- **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 package has an explicit CLI path that modifies agent configuration, which warrants a warning under the agent capability policy. Its npm postinstall is limited to repairing an existing opted-in wrapper and printing setup guidance, so the inspected sources do not support blocking it as an install-time control hijack.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Suspicious
- **Recorded analysis confidence:** 86.0%

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 explicit \`hippo init\` command can add Hippo behavior to detected agent instruction files and install user-level hooks. This is an agent configuration capability, but the inspected code does not establish an attack or install-time control hijack.

- **Trigger:** A user runs \`hippo init\` without disabling integrations.

- **Impact:** Agent behavior can be affected by the added instructions and hooks. No concrete malicious effect was identified.

- **Evidence paths:** dist/cli/init.js, dist/cli/setup.js

- **Review source:** ai\_review

- **Reviewed:** 2026-10-07T20:28:18.908Z

### AI review details

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

- **Mechanism:** The command detects installed agents, patches existing instruction files, and installs user-level hooks; a flag disables these integrations.

- **Rationale:** The package has an explicit CLI path that modifies agent configuration, which warrants a warning under the agent capability policy. Its npm postinstall is limited to repairing an existing opted-in wrapper and printing setup guidance, so the inspected sources do not support blocking it as an install-time control hijack.

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

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 86.0%

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

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for warning:** Running \`hippo init\` invokes automatic agent integration setup unless the user disables it., The integration detects existing agent markers and may patch their instruction files and install user-level hooks., The postinstall routine is limited to repairing an already-installed Codex wrapper and printing setup nudges., The scheduler’s daily maintenance runs Hippo commands in registered workspaces containing \`.hippo\`.

- **Evidence against:** The postinstall script does not install first-time agent configuration; the configuration changes are reached through the CLI init command., Instruction-file patching skips files that do not already exist.

## Affected versions and remediation
