hippo-memory@1.63.2

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 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.

Static reason

One or more suspicious static signals were detected.

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.

Mechanism

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

AI rationale

Evidence

dist/cli/init.jsdist/cli/setup.jsdist/scheduler.jsdist/cli/shared.js

Decision evidence

public snapshot

AI called this Suspicious at 86.0% confidence as Dangerous Capability with medium false-positive risk.

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.
