Make your agent's memory work like a brain. Hippo is long-term memory for coding agents.

AI Security Review

scanned 15d ago · by lpm-firewall-ai

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.

Static reason

One or more suspicious static signals were detected.

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.

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.

AI rationale

Evidence

package.jsondist/postinstall.jsdist/cli/init.jsdist/cli/setup.jsdist/scheduler.jsdist/cli/shared.js

Decision evidence

public snapshot

AI called this Suspicious at 81.0% confidence as Dangerous Capability with medium false-positive risk.

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.
